Fuel Pump High Performance Upgrade? (Page 1/1) |

I was looking through fuel pump applications on Rock Auto and I'm a bit confused. I found the following:
Using Delphi Pumps across the board:
Fiero V6 = FE0039: GP = 26, max pressure=87, PSI=50 https://www.rockauto.com/en...9208&pt=6256&jsn=607
87-91 Sunbird L4 Turbo = FE0113: GP = 20, max pressure=71, PSI=44 https://www.rockauto.com/en...0852&pt=6256&jsn=671
89 Trans Am V6 Turbo = FE0110: GP = 22, max pressure=70, PSI=44 https://www.rockauto.com/en...1571&pt=6256&jsn=549
1) So what am I missing here? Why is a Fiero fuel pump higher rated than a trans am turbo?
2) Why are the Sunbird Turbo (2.0L) and Trans Am Turbo (3.1L) nearly the same?
3) What pump are people that are turboing their stock 2.8L going to or is there even a need if the stock Fiero pump flows more than a stock Trans Am turbo pump?

It would appear the Delphi FE0039 is a little overkill for the application. Not sure why it's spec'd for that. But it should be good for about 220 HP, on a turbocharged engine. If you need more than that, the Delphi FE0114 also fits in the Fiero sender unit. And it's rated for 35 GPH (good for about 300 HP in your application). You'll have to trim the rubber pad under the pump a little, to make it fit.

I installed the EP381 pump (it dropped in without mods) in my Fiero, and it's been working fine with a turboed stock V6. Stock regulator and fuel lines as well.
It is suggested to perform the hot-wire mod, so that your new pump is supplied with full voltage: http://www.gmtuners.com/fiero/hot_wire.htm[This message has been edited by pmbrunelle (edited 07-06-2021).]

Is it a Delphi issue? I was just using Delphi because the other GM pumps weren't available to compare. So the stock GM pump for the V6 Fiero is a much lower capacity than the V6 3.1 GM pump?
What pump are 3.8SC guys using?

Couldn't find anything from them on RockAuto. What are the GP #s for those two? And what's the HP rating?

I couldn't agree more - especially if you are going to use E85!
