fuel pump install, help needed

**Ernies Imports** · 02-03-2008, 08:05 PM

All right, my 93 hi jet stalls out everytime I step on the gas.

I believe its my fuel pump because I have replaced everything else that could be wrong.

I would like to use an electric one from napa, sooo... do I leave the old one on and just plug the ends of it, then hook up the new one to the hoses ?
Or do I have to remove the old one?

Also what pump should I buy at napa, anyone ever done this before?

Also do I wire it into the key switch ?

Im good with diesel tractor engines , this is my first mini problem, so any advise is greatly appreciated

93 Hijet - 5 sp- 4x4 -air- ex cab- blue-660

Had a 9500 combine with a facet pump and our trencher also has this style. Both are diesel and have 1000+ hours each and no problems. Simple reliable pump and simple hookup. Be sure inlet side is filtered.

Hi jet,
which one do I use for my application on the truck ?

I know this probably won't help much but one would need to know the pressure required on the inlet side of the carb. I was just givng insight on the pump style that has been trouble free for us. Too much pressure may cause flooding. A carb mechanic should be able to suggest flow and pressure numbers for you.
Can you crank the engine with the pump to carb line off and get good fuel flow?
Have you checked the fuel filter?
I know, but I just needed to ask.

Hijet, I changed the fuel filter 3x already, new spark plugs, air cleaner. checked the dist cap, xx antifreeze, synthetic oil ect....

I just need to now which pump to buy.

It runs great when I first start it, then after it warms up, it still idels ok, my problem is when I put it in first gear I have to pump the pedal to get the rpms up so it will take off, or it just bogs down, then it has little power, and it bucks a little at 24 mph unless i pump the pedal for more fuel.

Other than that its a great little truck, (when it runs)

any suggestions ?

We put a Napa 3-4 psi pump on a Suzuki. Just have to hook up the hot wire, & ground to the frame. It's worked well so far.

Yep. That sounds like a fuel pump problem. As far as removing the old one. Is it external or is it in the tank. I would think you would want to remove the old one, although it may work just fine if you leave it in place.

Greg its external on top of the engine

Oh. That would make it a mechanical pump (not electric). I would bypass it but leave it in place unless you can have a plate made to cover the hole. Just don't mount the electric pump near the engine or exhaust. You need to keep it cool as possible. Connect it to the ignition (so it turns on and off with the key). I would temporarily install it in a convenient location and wire it up hot to see if it even relieves your issue before you get in there and make a day out of it.
