Hi,

I am in need of a replacement fuel pump for my 92 GTA I have done some searching and have found the AC delco unit #EP381 what is the opinions on this one or should i ante up and get a Holley/ edelbrock/ walbro unit? Car is not stock and is making in excess of 400 crank hp opinions thanks GTA.....

 

I wouldn't use a stock replacement pump with an exstensively modified engine. I run dual external pumps on mine. I started out with a new OE in tank with an inline boost pump but the in tank died after a few years and no more in tank fuel pumps for me. I drop enough fuel tanks at work to suit me and I hate in tank fuel pumps. If you want a good in tank pump, think about an Aeromotive FI pump. They can be in tank mounted and will easily feed your motor. They can also be mounted externally inline. Their smaller FI pump will feed 700hp. Its the one I use.

 

Thanks for the reply...

Do you have a Part/ model number for it? Also what else do i need to purchase for the install? does / will it use the stock sock or does the Pump arrive as a kit thanks GTA....

 

I would use a Walbro 255 pump. You can have one shipped to your door for a little over $100 and it will suppport 600+ hp.
