Fass Fuel System

[LowFly]

Adding a lift pump closer to the fuel tank will only reduce the amount of cavitation, it will not eliminate it. Remember after air/vapor is removed from fuel a net positive pressure must be maintained to prevent cavitation, so a pump close to the fuel tank will not eliminate cavitation. By adding a fuel pump, depending on the volume, cavitation could also be increased putting more air/vapor to your injection pump and injectors. Also remember, usually the number 1 source for air in fuel is agitation, the longer you travel the more air that is present in fuel. This is why a chassis dyno does not report the true horsepower while the vehicle is in motion!

Lawyer fees

I am sorry that I have to splash my feelings all over this web site, but!!!

I ,just like many others can see what is happening here. :-{}

I believe that if you two quit the legal battle, you would'nt need so much money to fill your lawyers pockets. And then you would be able to sell your product at a much lower price, and you would sell more, and, in the end, you would be happier knowing that you did'nt do something detrimental to a close relative, that would most likely follow to the grave. "That is when sorry will really be felt!!!" Because, how do you make amends then?

The Lawyers will not be able to help you when all the real damage is done. But they will be at home hugging their families with their fists full of cash, (that used to be yours), and they won't feel your anguish.

Furthermore, your time and money can be better spent on improving your product, or products, and the whole world would be better off then.

Oh yeah, how did it feel when you were both working on the prototype? The feeling can be had again. I believe that you both have great minds, and, I wish you both the best.

I am glad you are have good luck with the Fuel Preporator it is a good product. I am sorry we can not just give units away,



Brad Ekstam

I didn't ask for nuthin' for free. I asked for 5. 9 dyno numbers, offered to DO IT FOR YOU, and then BUY your product IF it does what you claim for HP.



Don't make me out to be a moocher.

All I hear is "entrained air, entrained air, blah blah, blah"



Show me the NUMBERS on a BOMBed 5. 9 and I'll SHOW YOU THE MONEY!

 

[Murle]

Well My mind is made up.



I just got off the phone talking to Brad at DPP. Ordered my FASS system. Had a good talk with Brad and liked the way he talked and the way he thinks.



I have read a lot about the FASS and so far I have not heard one negitive thing for a users of this product. That tell me a lot.



Thats, Brad for taking the time and talking to me about the FASS.

how the electric part stays alive--theory

OH, I finally figgered out how this electric lift pump is different from the dozens of carters that we as a group have been trying to make work.



It doesn't have "entrained air" going through it! Hence it will last forever.



Well, nobody else is offering a theory. I've been following LP theory and application on this board since May of 02. Relocate, replace, add pusher, gravity feed from in-bed tank, line upgrade, drill banjos, chuck banjos, which carter, what fails on the carter, pressure regulation, etc.



Apparently nobody but the MFG know what electric pump powers these things. That's good. That means that none of our boys have had to cut one open out of frustration yet.



see new poll.

 

[GIT-R-DONE]

For those that want to know: I am going to get my FASS installed soon. I do have the base of dyno numbers to go by as I just had it done recently at Fall Brawl at Kauffmans. I have done no other mods to the truck since the last dyno, so... ... after the install, I am making the trip back down, just to see for myself what the numbers are. I want to know if there is any difference in the system or not. I will not , however, install both products as I don't have the money or time to experiment with it in this way. The only thing different will be the weather for the dyno, I figure thats the best way is the same dyno for the comparison.

I will keep you posed as to what the results are when I am done.



This is installed , not for horsepower results, but for reliability. I have been curious to find out also, plus I get to see some of my new friends in the chocolate town area too Thanks Don

 

[WadePatton]

Fantastic!



Same dyno, different day, no other mods will be just what we're after here. Hope it really turns the numbers.



And we'll just have to guess as to the weather thing.



Of course I was going to do it same DAY, same dyno. But I have other testing/tuning to do anyway.



THANKS Don!

Hey Brad, go check the poll. We've read it all, now we want NUMBERS. Speaking of numbers there are $10,000 worth of YES's there and a pile of MAYBE's ($6,600). We're not waiting until the next issue of TDR.

STOCK LP

Well I took the top off my LP and found that the impellers are quite sturdy looking and dont appear to be the problem. my Lp sounded like it was laboring and was sporatic. upon disassembly the shaft was hard to turn. like I said b-4 the prob has got to be in the electric motor portion of the pump, weak, poor quality whatever who cares. dodge doesnt care. I do not think it would matter if the thing was pumping quervo gold it would still fail. so now here is the fix that we have all been wanting and waiting for. who cares if it adds any horse power or not I would bet everything i own that I cant hurt. How about peace of mind.

The dyno topic finally got to me I am going to contact the expert in Sacramento and see if I can dyno and then install at his shop and then re dyno, BTW I got the Fass system today, VERY NICE well built in every aspect, real nice piece.

 

[WadePatton]

No one has dissected a FASS pump yet.

Is it not electric?

Does it not have the same internal components as a stock carter?



Telling us that the OEM carter is crappy is not new business. Tell us HOW and WHY the electric fuel pump used in the FASS is different---BESIDES being in a fancy housing with all sorts of other goodies and features.

 

[Jetson]

Too bad it won't work on people with entrained air, or then again maybe it will. :--)

 

[jwinnie]

I have a question as I have never seen a FASS setup firsthand.

Is there some type of vent or return line to the tank? I figure with all this "air" being removed from the fuel (be it a small amount) it has to build up and go somewhere right??

TIA,



John

 

[LowFly]

Yes, there is a return line back to the fuel tank.



Brad

 

[Hohn]

I think I may have been one of the first TDR guys to see the FASS in person. It was last Feb at A&M diesel in Macon GA. Allen was looking to install it on his CTD-- said it was VERY highly regarded, and he was trying to figure out how to mount it up.



i need to call them and see what his results where. BTW-- Based largely on MY advice, A&M now advertises in the TDR mag. Good shop- great guys. unfortunately, they thought 275s were hot injectors! Imagine the look when i showed them DD2s!



I will have to go back there when I go EDM/twins



A&M-- Great guys, great service. Sold me my EZ for $490, and they're a SMALL shop... .....

I know these filtration systems don't actually change the timing, but that is one of the benifits they are claiming.

When a fuel timing box is designed, do the manufacturers (eg Edge) base their numbers on actual or theory.



Lets see if I can explain what I'm thinking here... .

(Assuming this air/fuel theory is correct)



In stock form the CTDs timing is a little retarded than what DC engineers had probally expected. So timing boxes are designed to advance the fueling. They are using theory and actual CTDs with a stock fuel setup to make their boxes.

Now, we add an aftermarket fuel supply setup, that is going to advance the timing a little more (that is what is being claimed, right).

So, for those of us running fuel timing boxes. Is this going to put us over the edge (no pun intended). Hohn, I know how you feel about the EZ.

What do ya think? Just thought I'd throw that out there.

 

[JTBMC]

I dont think the FASS advances or causes the timing to advance on the VP, sense it is pluged into the stock lift pump harness, I could be wrong.

What happened to Ted Jannettys FASS post that was here early this morning.

[LowFly]

Removing air from fuel will advance the time of any diesel engine. It will not advance the timing beyond what the timing of that engine is set at. The barrell and plungers simply compress fuel, once the fuel reaches a predetermined pressure fuel is then released into the cylinder. Air/vapor in fuel simply delays/retards the timing of when fuel is injected into the cylinder, the same way air in your brake lines delays the braking action. Any time you introduce air into a hydraulic system the air delays what ever action you want. All fuel injection systems on all makes of diesels engines are hydraulic systems. The reason engine manufactures do not have problems with air/vapor in fuel is due to several reasons:



1. The fuel tank in the test cell is usually at least 12 feet above the engine, this provides a positive flow eliminating cavitation.

2. The fuel tank is completely stationary, not agitating the fuel.

3. The hot return fuel is usually going to another tank.



I think this will answer some of the questions???

Preporator wrote: First,the effect: Air and fuel vapor, as is any gas, is compressible. Because of this, when it is carried into the fuel injector, it delays the pressure build-up which delays the injection. This retarded injection timing effects the diesel just as retarded ignition timing effects the gas engine, slow or spongy throttle, low power, rough idle, excessive exhaust emissions and increased fuel consumption.



Sounds like thats what he is saying to me.

Did it get deleted? Moderator? I'd be interested in his comments.

Brad,

You just confirmed what I was thinking. Maybe it's not enough of an advance to make it worth talking about, but I think the only question left unanwsered is: Do the aftermarket fuel boxes set the timing to limit considering the delay caused by air in fuel? And if so, will adding a Fass or Prep advance it too far.

Again, probally not worth talking about, but thought I'd mention it.



EDIT: Too far -- with a timing box installed
