Engine/Transmission (1994 - 1998) Electric fuel pump

[Bevis Malkin]

Will a truck run if I connect an electric fuel pump directly to the p pump

The answer to your question is yes, IF it’s the right pump.

However, you can’t get a more dependable and efficient pump then the original mechanical pump.

not to hi-jack, but I'd love to hear your opinion on best electric pump for the 12 valves BigPapa...I really dont like how burried the fuel delivery system/filter is on 2nd gen 12 valves...would love to have an upgrade that gets to live on the frame rail or something...

 

[BigPapa]

Unless you're at 500-600hp or more, an electric lift pump isn't an upgrade at all. As I said, you can't beat the dependability or fuel supply of the mechanical pump.

Unless you are part of a small percentage of Dodge/Cummins owners who own trucks until the wheels fall off it is entirely possible you will never have to replace the $110 stock pump. I change mine at 300,000 miles as preventative maintenance. The $500+ FASS pumps do not have nearly the same expected life. They, as well as AirDogs are not an upgrade in any sense of the word.

Cool thanks, embarrassing as it may be, I've killed 2 lift pumps in the last 30k, but I believe its because of the way my waste oil system is set up...

I've only got about 180 k on my 97. I thought I had a fuel pump issue once and went ahead and ordered a replacement for it. Turned out not to be the pump so I still have a stock fuel pump standing by. I'm with GAmes, it's darned hard to beat the stock pump!

I have seen some threads about getting guide bolts for putting the pump back in place. It is difficult to push it in place, and start the stock bolts.

If you own a tap and die set, it really is simple to make your own on the cheap. I gauged the stock bolts, took a 3" 1/4/20 bolt, and ran the proper die down to about 1/2-3/4". It doesn't have to actually hold anything, just guide it into place. You shove it in, start the other stock bolt until it's snug, pull out the guide and replace it with the stock one, you're done. I found that to work very easily.....OK, and I'm cheap!

yeah, I installed studs on mine after the first replacement, so much nicer.

 

[BigPapa]

No need to make studs from bolts. I bought an exhaust stud kit at O’Reilly’s that had several 8mm studs and nuts in it. They were a bit longer than necessary but it was no problem. MUCH easier to install the pump with studs.

If you’re going through the mechanical pumps like that, you’ll be throwing your money away with an electric pump. Are you figuring your replacement parts and labor costs into your “savings” from alternative fuels?

Tell us about it if you don't mind.
