Trying to find out pump output for an AC Delco fuel pump EP386. Will this feed the GEN III type engines? I think it needs around 45-55 psi? Don't want to do this over again.
Found one at Rock Auto for like $55. Found some other places online like getgmparts.com for $36. Is this for real? anyone ever used them? reccomendations?

Thanks

That pump will not work. It is rated at 14.5-30 g/s at 83 kPa which is 12 PSI

It is used for the old (1980-1996) throttle body systems

What do I need? I've been told guys have used walbro 240 0r 255. Found the 255 on ebay. What should expect to pay? Ebay is around $100 - about right? Is this going to fit into a stock sending unit hanger? What about the wiring? Will the stock GM sending unit wiring fit the WalBro pump?

Thanks

What car or Fuel Tank is this going into ?

Racetronix is a good source for the Walbro pumps and also wiring harness and kits.

03-up gen III 4.8 or 5.3 INTO 84 Chevy SWB originally 250 cu in 6 & 3 spd

Not sure what connector/wiring the stock sending unit will have since it was a 6
Thinking about using an '87 FI sending unit w/ the - Walbro 255 pump-stock tank. Looking at Rock Auto's Spectra OEM style sending unit - part# FG05M. Trying to figure out if this pump will fit stock hanger & wiring on the OEM sender.

that spectra part looks correct. Just make sure you get the one for what side tank you are using.

a pump for the 96-97' chevy pickups does put out enough pressure and will fit into an existing old style gm sending unit that was used with most tbi equipped vehicles.

The EP-381 is what you need.
