Engine/Transmission (1998.5 - 2002) Satisfied with aftermarket lift pump setup?

[Gary - K7GLD]

This poll is intended only for users of *commercially available aftermarket* LP setups (FASS, RASP, etc. ), and will hopefully assist in arriving at some indications as to their real-life ability to deliver the trouble-free system operation their users bought them for, as opposed to the home-brew setups such as added Carter pusher pumps.



It might also possibly give some indication as to actually how many users of aftermarket systems there ARE on this board - a very helpful factor in arriving at failures/problems-per-hundred units...



Be perfectly honest, if a condition exists you would complain about with a stock setup, report it here if the aftermarket setup does it.

Hope this counts, I have the 8 psi carter mounted near the tank with the stock pump still in it's original location. 19psi idle / 15 cruise / 10 WOT. No problems so far and it only cost $100 with all the parts. I couldn't be happier Oo.

FASS pickup mod.

The FASS system I installed last year is working fine.

I have good pressure which is why I bought it, 14psi idle, 13 psi cruise, 11-12 psi wot. Having read many threads on this site I feel the pickup in the tank is part of the problem. I plan on modifing the pickup as some have done on this site, there is a ton of information out there! The stock pickup is restrictive and I beleive that is part of the reason that I get a gurgling noise out of the FASS. Many members have mentioned this in posts about fuel module modifications. The weather is a bit on the cool side now to be dropping the tank to remove and modify the module , it is on my things to do list this spring!

I've had the FASS for almost A year now. The thing I like about it is , it keeps the fuel warm enuff so that it doesn't gell up on me. I always try to run as much #2 fuel as possible in the winter. I very seldom run anything blended.



A couple of weeks ago it was -25 degrees below and I had my truck running in the back yard , so I felt the pump and filters with my hand and I could feel that they were warm enuff so that I didn't have to worry about troubles. Even with strait #2 fuel in the tank , it runs trouble free in this miserable weather. My engine warms up faster with #2 fuel , and it makes A noticeable difference in power output.



The thing I HATE about this FASS system , is the fact of having to shut the engine off when I fuel up. It's either that , or I get A bath with fuel if I don't...

I just installed a FASS system and they have changed the location of the fuel return line. They have it located in the filler tube hose not the vent line as they used to. Maybe you could get the piece that installs in the filler tube to let you have the engine running when you fill the tank. I am pretty sure you can get the part by itself. The part number is RM-1002.

Fass, very satisfied, constant fuel psi at 15, idles more smooth.



CMAC... -25 below, in Virgina?? Wind chill only effects exposed skin.

Air Dog, works great!

 

[GKinney]

F. A. S. S. very happy with it especially after installing the 1/2" suction pipe in tank!! My advice to fass owners... . junk the stock module!!!

I believe it said Virginia MINNESOTA... ...

 

[CMAC]

Thank you mopars1 for the part number and info. I was unaware of this change and that part is on the must have list for me now.



AKDrifter , just so you know our Minnesota state record was set on Febuary 2 , 1996 at -62 degrees below zero!!! I remember it like it was yesterday...

Almost one year on FASS. Not one single problem, and constant 20psi idle-WOT.

 

[Mad Bomber]

Fass since last June. Problem with P/U assembley, I dropped the tank,cut screens out P/U assembly,problems sovled.



Chuck E. this is really a must do and works great.

 

[The Lockguy]

I have a F. A. S. S. system and it made a big difference in the idle and WOT. Couldn't be happier. I will probably do the tank mod. but, at the present time, it works fine.

I've had the FASS 95 gph version for about 3 weeks/1500 miles. I bought it as a LP replacement and VP longevity aid.



Pros:

- It works flawlessly in terms of performance; truck runs as strong as ever and idles more smoothly (it honestly does - I'm not just repeating other's claims).



- I personally believe it's a better pump in a better system, and while only time will tell the tale of reliability/longevity, I think having it's own by-pass to the tank makes life easier and more stable for the pump.



Cons:

- I still have a minor leak which I'm afraid is coming from the unit itself (I've re-done all my connections to/from the unit and it still leaks, thought it's so slow it's hard to tell where from). I have to drop the unit and I'm not happy about spending another day bathed in #2.



- The location under the bed in front of the rear wheel bothers me. The unit is constantly wet and filthy, and while maybe this is fine, I don't like it. I'm going to get the factory fender liners that were left off the '02s and see if that helps.



Tips:

- Search here and elsewhere and read before you install. Important tips like clamping the suction line directly to the fuel tank, discarding the kit-provided quick-connect, will save you a lot a time.



- Be careful where you route your fuel lines, and inspect after a few hundred miles to see if there's any chaffing, etc. Remember that your bed in soft-mounted to the frame, so it can move relative to the frame. Don't mount the unit so high that the bed will hit it if you dump a yard of gravel in back (or in my case, a cord of wood), and make sure no fuel lines get pinched in such a case.

The better idle claim is sorta hard to explain, unless the system that was replaced was VERY poor or non-functional - PSI is PSI, regardless of whether it comes from a FASS, RASP , OR the stock setup - the VP-44 sure doesn't know the difference!

Have had the Airdog since July, works great.

The FASS is doing it's job, removing air, allowing for more consistant injection events. Maybe. Or more likely I think the factory quick-connect at the tank was letting air into the stock system, and now, post FASS install, my line is clamped right to the tank. So that hose clamp that came w/ the FASS is responsible for quieting my idle. Maybe a $. 79 hose clamp is the cure for all 24V fuel system woes!

At some point in time, I'd like to substitute a section of clear hose between my last fuel filter and the VP-44 to at least try to visually see what the fuel flow looks like at that point...

 

[BRUTUS]

The AirDog preporator has performed as expected for the past six months. Reading today's posts reminded me to check and drain the water/fuel separator for the first time. When I opened the drain, about an ounce of fuel came out and then the flow stopped. I then started the engine thinking that the pump would allow more drainage from the filter... BAD idea!

The engine stopped in a few seconds and won't start again.

I left a message for Charlie Ekstam to help me out of my dilemma tomorrow, until then, any advice or suggestions?

Would two ounces of fuel out of the system cause it to pump air? Bumping the key/starter to activate the pump is no help.

Try cracking the injector lines and cranking the motor to bleed any air that may be in there.
