Topic: Electric Fuel Pump Conversion Questions

[Plainview]

Hey gang,

Going to convert my '84 to an electric pump.

1) Where is the pump located on the 22RE equipped '85 - '88 trucks?  I'm guessing it's back by the fuel tank.  It's not an in-tank pump is it?  (My Google-fu has failed me here.)

2) Would an OEM style pump make sense, or a lower pressure style?  I'm just feeding my Weber 32/36 and have a pressure regulator set to 4 psi currently.

2a) Any suggestions on which pump to run would be appreciated.

I will run an oil pressure switch for safety.

on 22re, pump is in the tank. I'm sure an inline electric pump with regulator would work http://www.summitracing.com/parts/atx-e8012s?seid=srese1&gclid=CPekvpvPr8wCFQFsfgodzV4P7A

I would just run an external pump at low pressure.... the fuel injected pump, that is in the tank runs a lot higher pressure

Thanks guys.  Its odd that I couldn't find any online pics of a 22RE fuel pump...

And yeah, makes sense to run a basic, low pressure pump as I'm stepping it down to 3-4 psi for the carb anyway.

would be the in tank pump for the EFI








here is an electric, low pressure pump

you can probably find something a lot cheaper than LCE on like Jegs or Summit

I'm not sure why you would get rid of the manual pump that a 22r comes with. They work great. If you do decide to go with an electric pump for whatever reason. Go to the parts house. Get a universal low pressure electric fuel pump (mr. Gasket has one for like $35). Get a pressure regulator as well. Set it to around 7 psi and go for it.

All that said. Been there done it, hated it. Nothing works as well as the oem pump.

I agree I like a mechanical pump too.  OEM will be best though some of the aftermarket ones are JUNK!!

I'm gonna buck convention here, but I've run electric pumps since I bought my truck in 99 and run the beloved (garbage) weber carb.  Tried different styles and different locations, and the cheap diaphram ones will leave you stuck, which sucked cause I had them mounted right outside the tank.  I've been using a holley red for about 10 years without issue.  Well, I did have issue with it starving for fuel when I tried running a regulator, but have since ditched that and it's been fine since.  And this one came out of the supposed bad pile of pumps off a generator at work, so 

Mine is currently in the engine bay across from the carb, but should be closer to the tank.  The majority of them are designed as pushers and should be run as near the source of fuel as possible.  The oem pumps always failed on the generators I used to work on cause there was often over 10 feet of hose running to the fuel tank, and some were over 2 feet deep and took a lot to get the fuel moving.  Issues were much less when I started mounting the holley pumps as near the tank as possible.
