Adding a fuel pump

[jmeador88]

I have a stock 94' gt (3.73 gears). I plan on adding longtubes, underdrive pullys and intake this spring. My question is I have a Holley blue fuel pump just laying in a box and I have thought about putting this on my car. My questions, can you leave your in the tank fuel pump and add this also? I know it probably will not help power wise since i still have stock injectors, but i figured it wouldnt hurt anything either. I kinda just wanted to stick it on there because if I run into a good deal on a supercharger I will have the fuel il need for bigger injectors? What are your guys thoughts?

I think the blue pump is for carb applications. It won't work for you, it will not deliver fuel at a high enough pressure for fuel injection.
Get a 255 intank for now and add a 255 inline when you add the supercharger.

The holley blue is 110 gph at 14psi. I got to thinking if I put a 255lph pump in line, wont it starve my factory in tank pump? Sorry for the questions havent messed alot with fuel pumps on a gas burner much, espeacially fuel injected.

Im running my setup like i suggested with no issues. I believe the inline will push the fuel and not starve the intank pump.

blue is a carb pump. 14psi isn't enough you need 40

no need to run two pumps unless you need the volume and today there are plenty of intank pumps that can feed a 500 rwhp motor
