I need help on installing the inline fuel pump for my drag 3 kit..i believe its a bouch fuel pump..what end of the fuel pump goes to the fuel rail and what end goes to the fuel filter..How do i know if it working properly,and install correctly.plmk thanks

 

uh, i thought mine said, in and out...but i could be wrong....anyways, the bottom of the fuel pump should be connected to the fuel filter side , and the top (the side with the connection terminals) is the side going to the fuel rail. it should be marked, positive, and negative....you will hear it buzzing....just make sure you wiring it up right otherwise you will be starving your motor from fuel!

 

if it's connected to your firewall, and it'll be hideously loud Bzzzzzzzzzzzz. turn on the blinkers to hear BzzzBzzzBzzzBzzz, it's kinda funny.

 

Yeah I know, when I had mine it, everyone thought my engine had a bomb in it. Everyone was always asking whats wrong with my car.

My inline fuel pump said in and out also. It was an Airtex though, I didn't know Drag kits could even come with a Bosch pump.

 

my airtec didnt say in and out... it say fuel with arrow ->
