electric fuel pump question
 

no, not my race car... back to my suburban. i am going to put a fuel pickup in the bottom of the tank, and plumb it like my race car with an electric pump and regulator. plan is to put both in rear of vehicle...
here are my questions...
1. with say 7lbs of pressure should i still go through my mechanical pump ?
2. what pump would you guys recommend, remember flow is not as important as a pump that will survive 10-12 hours of continious running (i am going to belle rose straight thru!)

thanks,
captain jack

p.s. if this does not fix it i will have a 1991 suburban with less than 100,000 mile on it, brand new motor, brand new fuel system and absolutley no rust anywhere for sale ... DAMN CHEAP

Re: electric fuel pump question
 

if it were me, i'd use an OEM/Delphi pump in the tank...notice the "oem" part of this, not airtex or another aftermarket piece of...
you ARE still running the stock throttle body efi for the truck, i'm assuming..?

Re: electric fuel pump question
 

I wouldn't use any aftermarket, or parts store replacement pump. Only genuine AC Delco. Btw, 7 psi is way low. 1991 TBI system needs 10 to 14 psi to run well. 12 to 14 preferred, especially for towing.

Be careful with the A/C delco stuff.Not the same old A/Cdelco we are used to.Take a look at Walbro or Ractronics they might have something for you

Re: electric fuel pump question
 

Don't know if you have a shop, or not. I made the mistake of installing too many Walbro pumps. Had to pay too many wrecker bills over failed Walbro pumps. I stopped buying that crap, and out of my pocket bought AC Delco pumps to replace them. I have had no comebacks with OEM plumps. Walbro was OEM for Chrysler, don't know if they still are. Chrysler had way too many pump failures also. From past experiences at my shop, I would never trust or recommend a Walbro pump.

Re: electric fuel pump question
 

Delco doesn't make their own pumps,actually Delco makes very few of their own parts. They contract out to suppliers such as Carter,Raybestos,National, BCA etc for many parts and get a lot of "mileage" out of marketing them under the AC Delco name. I have been in the parts business for more than 25 years and had managed an AC Delco distributorship for almost 10 years,before moving to NAPA.

Re: electric fuel pump question
 

I didn't buy AC pumps from parts stores, I ordered pumps from the GM dealer. Ford pumps from the Ford dealer. I avoided that kind of work on Chrysler products, since the local Chrysler dealership's parts departments did not deliver and their discounts weren't deep enough to make it worth the trouble of someone having to drive across town to pick them up. Ditto International Trucks. Haven't done that kind of work at all for a few years now.

Last pump I bought from NAPA said Walbro right on it. Forget now who's name was on the box. Bendix, Borg Warner, and non-GM AC Delco pumps were re-boxed Walbro also.

Re: electric fuel pump question
 

Yes Walbro had some issues but offered warranty on even out of date products.It was only on a few # s.I have also noticed A/C Delco from the dealer can be different than parts stores??Good info here.I have Walbro pumps in both my cars with no issues.Racetronics also makes some nice stuff.
