I have a 94 Civic Coupe ex with a Greddy kit with intercooler running 5psi, I am scare to run anymore boost without any fuel inrichment. I was going to get a Intank 255 Fuel pump from APE. I hear alot of Inline Fuel pump but I have one question, Do the stock fuel pump stay or I have to get rid of it with the inline or they both work together.

 

stock stays.
