Engine/Transmission (1998.5 - 2002) ONE MORE TIME, the ultimate fix for OEM lift pump

[Whitmore]

I want to try one more time to let all TDR Buddies know how to fix the OEM lift pump problems, should we installe a pusher? NO IMHO, many many are using this and it does work and deffinatly alot better than the OEM crap set-up... ... ... ... I am not trying to bash the pusher but IMHO it is only second best.

Please take a look at this if you want alot less trouble with your fuel system



... ... . back up a minute and think outside of the box, I did this and it works well and it will help your OEM lift so it wont have to work as hard, prolly get much better life from it too.

Get a in-bed auxillary tank and all the accessories for your aux tank, IE; level gage, supply port, return port and one more port if possible but not manditory, now use an 8 AN fitting and get a SS braided line to feed your oem lift pump , leave the lift in its original location, then take the return line from the VP and install it to the return port, wire in a level gage to the cab so you can monitor level at all times, OK now buy a small frame mount pump from the local auto store and mount it on the frame by the OEM tank port , hook it up so you can transfer fuel from OEM tank to new Aux tank, If you have no port available for this you can "T" into the return line from the VP. One more step to help out would be to do a SS 8AN line from OEM lift pump to the VP 44... ... ... ... ... ... DUDE you will never be sorry for this bomb... ... ... ... . Kevin



P. S. I cant understand that with all the OEM lift pump problems why others dont do this mod, think of it ... ... ..... with this mod the lift will have Possitive head pressure instead of a Vaccumn In other words why keep trying to make a fuel system work that was doomed before the first one was built!!!!!!!!!!!!!!!!!!!!!!!!!!!



Please please get away from the OEM set-up it is crap , Remember one thing ... ... ... ... If you polish a turd ... ... ... ..... it is STILL a polished turd... ... ... ... ... Kevin

Kev, I think it's a great mod. to try. Problem is many dont want to give up the bed space for the aux. tank, or the $$$ and time to do this mod. It really is very similar to Csutttons aero pump mod. , a true gravity feed to the transfer pump. I'm glad it's working for ya for sure !!! Also glad to see you back on the board .

Kevin, I always heard that you couldn't spit shine a turd. :-laf

 

[Sky]

yea what bigsaint said.

whitmore--Big Saint hit it on the head--bed space for some of us cannot be spared--for those who can spare it, it's a no brainer to use an in bed tank for true gravity feed, the other option is my setup for true gravity feed--been going for 14 months now with untold shutdowns and startups---chris

 

[WadePatton]

That's all fine and dandy, but I've got no use for an extra tank.



I'll just keep popping LP's on for $150 a throw.

 

[dresslered]

Dang, it sounded like such an easy mod too! I forgot that I carry a huge slide-in which would pose a bit of a problem. I guess I will continue to take all the downhill routes.

 

[Bigsaint]

Sham Shame, everyone knows your name

David, David,David... . in your case you just need to throw the transfer tank on top of the Bigfoot, for EXTREME GRAVITY FEED !

I'm really surprised you didn't think of that, being an engineer and all

I bet I'd just love the new center of gravity as well. Can you say whoaaaaa! Lean baby, lean! :--)

RE: Spit Shine....

Hey John,



Let it dry in the hot sun for a few days first

Yep, industrial diesels have been using this system for decades. Go into an engine room and look up in the rafters - you'll probably see a "day tank" feeding each engine, or a large common day tank feeding all of them. The diesel fuel is pumped from the outdoor storage tank to the day tank by a transfer pump. This pump is controlled by a level controller in the day tank. The day tank provides a positive head to the inlet of the injection pumps (or, if used, the engine-driven low pressure supply pump); the same system is used on common rail engines to supply the common rail high pressure pump, again with or without a low pressure supply pump.

Hey Bigsaint -

Hey Scott, how's your lift pump making out ? I see smokindiesel.com offers the kit that you have on your truck. I'm looking for a permanent fix for mine before it goes south.

 

[Ncostello]

Why cant someone just design a lift pump that works for 200,000 miles. My 84 F-150 6-cyl has the original fuel pump at 198,000 miles. Kinda sad that a lift pump will last only 10K, 20K... maybe a 100K. The worst part about the whole deal is who knows when they will quit... or destroy a injector pump. Its depressing when you look a the rest of this great engine.

 

[Bigsaint]

So far so go, Rattlebox. Been on for 5 months now. Just towed something for the 1st time, psi's still good to go under a fairly heavy load.
