Engine/Transmission (1998.5 - 2002) FASS or not?

[blacksheepdiesel]

steved,



steve, steve, steve. I assume that is your name?



The TDR has an incredible feature called a search function. It seems as though you want to disagree with anything I say and discount my sources so may I suggest you use the search function to find the answer to your question. Please permit me to go so far as to suggest using the words "FASS" and "Fuel Preporator".



Oh, you may also want to search for "cavitation. "



Godspeed,

Trent

I have read those, and I still didn't understand how we get from "no air" to "some air"... cavitaion is something totally different, you are actually pulling a negative pressure or vaccum...



But I guess that was too much to ask.



I researched the FASS threads last year before I bought my FASS (the reason I didn't buy one of the "others" that were available at that time), and I have kept pretty involved in FASS threads since then to be aware of any shortcomings.



Again, I'm sorry it was too much to ask for an explaination.

steved,



Steve, I guess you missed the fact that I addressed my original post in this thread to SilverSage. He had asked questions and had not received answers to all those q's so I was simply trying to help the guy out. BTW, his questions were the result of the main FASS shortcoming, poor customer service after the sale.



Once again you choose to not believe anything I say or the sources I refer to. Therefore I choose to not answer your question. You are a free man, Steve, and if you want to choose to disbelieve certain things it is fully your right to do so. You are also free to choose to keep your disbelief private and it is apparent that you frequently choose to not do so.







SMoules,



It has not been my desire to hijack this thread, I was simply attempting to help out a fellow Cummins man.



Godspeed,

Trent

The fact is the FASS threads you refer did not answer my questions... I know exactly which threads you refer and while some people might take it as a grain of salt, I don't understand the outcome. Actually those threads are more the FASS/Airdog father/son arguments.



And sorry that I'm not SilverSage, I guess I asked a question that you can give an answer to someone else, but not explain that answer to someone wanting more info.



It isn't that I don't believe their answer, just that I'm not able to follow the logic based on what I know and understand.



Again, I'm sorry I troubled you with such a difficult question...

My E-mail has been down all this morning and out of the office half the day yesterday. I am working to get the issue fixed with my e-mail. Sorry, i did not recieve a new notice on this thread.









1. Is there a good, safe way to plump the FASS right to the injection pump?

First off, what part number do you have? We have 2 differant kits. Ones that use the stock LP and ones that dont. If you have a 150/150-1009 then no. You can not make this work. Your system will not push 45 PSI needed. If you have the 150/95-1009, then yes. You can convert this kit. You can push the pressure. ALSO you can use a SBC fuel pump block off plate to cover the pump hole on the block if you take the stock pump out. You will need to relocate the injector return line to the stock IP return line. This is low pressure and easy to do.



2. Will it harm the injection pump or performance?



No..... both kits will work great with your truck.



3. Is there a regulator that would help?



Regulator is in the FASS. BUT again, but max pressure is depedant on what kit you have.



4. Does the FASS really have a fuel heater?



Yes. You have to plump heater hoses to the FASS to take advantage of the engine heat. BUT honestly, i really dont see a need for it if you run additives in the winter like you should if you are below zero on a constant basis.



5. Is it safe/good to remove the pre-heater/strainer & lift pump, I can cut a plate to cover the hole.



Its safe if you have the FASS. BUT again, this all depends on what kit you have.



6. If its bad to remove the mechanical lift pump can I eliminate the pre-heater strainer and go from FASS into the lift pump. (making a shim to keep the lift pump the correct distance away) If this is so what about the factory fuel/water separator?

Isn’t simple better??



See #4 on page 13 If this is the kit you have... . this is how it should be installed. If it isnt, it wasnt installed correctly.

I have a 150/95-DO-94-98 (95GPH) going into a P7100

The Serial Number you gave me on the other thread shows to be a 150 GPH. You can tell real quick: Look for a "A" or "B" stamped onto the motor base.



A = 150 GPH

B = 95 GPH

Not to add to the Fass bash, But I have to agree with the service issue, or lack of. Having a pressure issue with my own,(and the performance of the truck reflect's it) The basic answer I recieved is it must be your FP gauge or something else, it can't be a FASS PUMP issue.

NO sir. I only suggest checking all the other options first before we condemn the FASS/HPFP. I suggest the others ideas because i see TONS of fuel pressure gauges mess up, even more isolators, and suction restrictions on the pump pick up that cause pressure issues. My goal is to have the issue thoroughly checked out before i go off and send out a replacement pump that will do the exact same thing when installed. I am an ex-mechanic. I never liked throwing parts at a problem. If we can figure out the issue before we get that far, saves everyone time and money. If your FASS/HPFP is in need of repair, and all other options are exhausted, by all means, we will fix it under wnty or otherwise.

 

[dknoch]

Hey, just a heads up, I had a warranty denied for a vp-44 because I had a FASS on it. Total BS, but another dealer was able to repair it under warranty. Just letting you know. Good luck!

If this ever happens..... please get it in writing. We are very interested in this.

I am not condemning the Fass pump, but like I said the dyno sheet reflect's what the FP gauge is showing me. Pump, maybe, or possibly something else. But what would it hurt to throw an 18-20psi spring at it, at the cost of cent's to Fass? To me it's all about the support after the sale of a product that keep's me coming back. Where I am headed as far as performance goes, I'm sure I am going to have to upgrade pump's. But the question is, where do I go from here. Thank's for your time.

Hey... I got no issues sending a spring to fix a problem. My thing is that the springs rarely cause problems. I have had maybe 2 ever give me fits (SteveD was one and his was very weird). So based on that info that I have to my disposal, this is why I suggest the things I suggest. Even a cents add up to dollars. Its going back to that whole "throwing parts at a problem" thing. Every situation is differant (AND some not). And must be handled as such. I dont like talking to people more than once over the same issue if i can help it. Fix it right the first time... .....

 

[BBRam]

I very well know about dollar's and cent's. I have spent plenty in a short period of time with a goal in mind. Now that everything should be in place, something is just not playing well with other's. And believe me, I am crossing every avenue to correct it.

OK then..... mind giving me a link to you issue here on TDR? Im having a hard time remembering the problem you were having.....



Nevermind, Found it... .



Like i said, all i asked you to do is check a few things out for me. You never got back to me and let me know what you found. I dont have ANY issue sending a spring... but i want to work with someone that will give me some effort back in my direction to solve a problem. Again... your issue did not sound like a spring issue. I can send you a spring... . but im pretty sure you will have the same problem. Like i said, contact your selling dealer... . and i will get you that spring you are wanting to try.

 

[CrewCabDiesel]

Before you get too carried away check your power connections on your Edge comp. I had the same problem and the P216 code was due to a loose ground wire on my Edge comp. It was recommended to me to run a direct ground wire from the battery to the Edge and I haven't had any problems since, that was around 140,000 miles ago and knock on wood, I have the same VP44 still at 203,000 miles . Also the edge connections to the positive is a joke and I would also soldier the positive connection to a switched circuit. I pulled a 10 gauge ground wire from the main battery to hook the edge and other toys up to.

Hope this helps

I think it would be very simple and easy to eliminate the lift pump just pull it off and pull the rod that contacts the cam out, reistall pump and voila not functioning lift pump. You don't need a fuel heater if you are running the proper grade of diesel ie winter in winter or add conditioner. If I had the bucks I would run and FASS on my truck my brother's '01 runs awesome, more power, smoother idle and better fuel economy with real filters. We also have one on an old 855 Cummins which now hardly smokes and has more hp. Simple, effective, but is too pricey. I'm still having troubles with my 12v and I wish a could try and FASS to see if it would help. If you want good help with installing a FASS phone Piers or Pittsburgh Diesel those guys know their stuff.

I'm waiting on a rail pressure gauge, and a dual feed line to go onto the rail. These will allow me to moniter what is going on in there, while eliminating a pressure relief valve issue. Like i said, I am covering all avenues. This is my daily driver, and I have been busy with other things also. I want to tackle everything at one time, so that is why I would like to have all of the pieces together. As far as the Fass pump itself, I would really doubt that is my problem. But droping to 6lbs bother's me, when other's do not. At 70mph it is bouncing back and fourth bettween 15 and 13. I appreciate your help, that mean's something to me, and I am not out to rob anyone. THANK'S, BRIAN

 

[LowFly]

Hey... . shoot me your SN. I want to run it. I had an issue with a pump with Low pressure on a Dodge that some how the dealer he got it from used a D-max kit..... which is set up with a softer spring... ... . worth a shot at least.....

Suggestion: leave all your stock LP and filter in place. Hook up the FASS the way its supposed to be, but leave all the stock equipment in place.



Reason: when the FASS leaves you stranded on the road, or for some reason it quits, you at least have a way to get back home. You wont find these parts at a truck stop and waiting for customer service out on the road is not fun. Good Luck
