Engine/Transmission (1998.5 - 2002) Lift Pump Alternative ?

[Stroker Smoker]

Someone help me out here, After replacing the lift pump on dad's truck I got to thinking. Why couldn't someone use a mechanical fuel pump from a 12v to feed the VP44, they have great reliability even when used with a heavily modified engine.



Some possible problems that I thought about would be no lobe on the cam, and no mounting boss on the side of the engine.



Just a thought

Many vendors have addressed these issues and have complete kits.



I will have this setup on my truck in the next few weeks.



Other things to consider are the spacer behind the 12V pump, all the lines to hook up to the old system along with the proper fittings, pump itself, cam, tappets, smiles, misc bolts, smiles, never having to watch the gauge again, smiles, watching the gauge gain pressure as you stomp it, more smiles, you get the point.

I really want to go with an after market pump after I have the VP44 replaced (mine's on it's death bed) but worry about supplying enough fuel with the exsisting lines, tank module, etc. .

Does anyone remember the thread posted here where the guy bored a large hole in the fuel tank and installed a nice bulkhead fitting with 1/2 inch nipple to feed the pump from the bottom of the tank. That seems like a much better way to go. I just can't find that thread. There were a lot of pictures attached to show how he did it.

I don't know which pump (FASS or Airdog) I'll go with. . but want to supply the fuel from the bottom of the tank and by-pass the internal fuel module altogether.

Thanks for the replys. I already know about the aftermarket fuel systems. A fuel pressure gauge is on the way to monitor the new pump. We weren't worried about the lift pump since the truck is nearly stock, But I guess we were wrong. At least it was covered by warranty.



I was just thinking that a mechanical fuel pump is relatively cheap and greatly reliable. There are a large number of 12v trucks with hundreds of thousands of miles on the stock lift/supply fuel pump. Plus it is one less piece of electronics to depend on.

A while ago...

In my thread called "Operation Lift Pump Longevity"... TxDieselKid had a link to a bottom sump kit that was very nice. Scroll down this page of the thread and you'll see it and the link to the distributor.
