What is the best way to upgrade my lift pump? I be leave my stock pump is gone now and there a Chrysler one in my tank

---AutoMerged DoublePost---

A shop did all that work for me so I'm not sure how that all worked out

 

get a fass titanium and a draw straw 5 from vulcan performance...

draw straw 5 is made to replace the in tank pump and installs directly into the fuel canister. be sure to get the fitting to put the fass return line in the canister as well to avoid 1/4 tank issues.

 

Or you can get a sump instead of a draw straw.

 

I would never recommend a sump for someone with an in-tank lift pump.

1. they have to drop the tank and unhook that pump anyway.
2. sumps are NOT road legal
3. giant hole in the bottom of the tank.
4. sumps only delay 1/4 tank issues to 1/8th tank. they still suffer from fuel slosh.

draw straw 5 on the other hand.

1. made to retrofit into the in-tank pump canisters
2. 50%-150% cheaper than a sump
3. eliminates 1/4 tank issues completely if return line is located at the canister
4. legal for use on public highways
5. no hole in the tank at all.


I run the modified liberty module in mine which is essentially the same thing..
holds solid pressure with no fluctuations or drops/spikes in pressure even when the fuel empty light is on and the needle is in the red while intentionally trying to make fuel slosh happen... fill up was 34 gallons after the test.

would love to see a sump try that...

blue line with the 08-JIC fittings is the 1/2" draw straw 5, blue line with the QC fitting is the airdog150 return line, and the black QC line is the VP44 return line

start of the test...

 

I did some reaserch an I am deffinetly getting an air dog kit, do I need the 100 or 150 tho? I might up grade my chip to an edge juice next year , if that matters

 

the edge j\w attitude cts is a good choice been running mine for 3 years now i believe, an overall good programer to have in my opinion.. i went ahead and put the AirDog150 on my truck at the same time i put the edge on havent had any trouble with either of em. good luck with your choices

 

new airdogs are nothing like the old ones...there are more airdog and raptor failure threads on cummins forum now than I can count

airdog used to be a great pump years ago, but in the last couple years they have had nothing but problems with pump seals leaking diesel into the electric motors, pressure regulators not holding pressure, air leaks in the new quick connect fittings, etc...

FASS has had none of these problems and is still using JIC fittings like airdog used to use back when they were still a good pump.

I would love to root for airdog, as I have a 4+ year old airdog150 pump that is still going strong, but after the original owner sold the company and their product quality immediately falling off a cliff, plus how they have been treating their customers lately...just can't stand behind them anymore.

 

Ok thanks for the heads up ill go with FASS fur shur. What size is appropriate for me tho? The 95 gph or 125 gph (45psi)

 

if you plan on under 500hp than 95GPH, if you plan on over 500hp in the future, than 150GPH. and you don't want a 45psi regulator unless you are going to be running a p7100 injection pump.

you want a 17psi regulator. 14-20psi is a safe range for the vp44.. up to 25psi is still fine to run. I wouldn't try pushing 45psi through...you will never get the truck to start at that kind of pressure.

 

I was thinking 95 gph as well. I'll probly never even come close to 400 hp. Why wouldn't it start ???
