okay, im in the middle of a swap from my v6 to a v8 i was wondering is the fuel pumps between the two have an significant differences

if possible instead of pulling down the gas tank and changing out the fuel pump i was wondering if its possible to keep the fuel pump thats already in place an use it with no problems?

bump, anyone?

Are you keeping a return style fuel system or are you going with a returnless system? If staying return and not using a 98 ecm then your pump should work for mild performance. If your gonna have a returnless system then you need a new pump, and lines.

I didn't realize you were doing this on a 2000 v6, Is that system a return style?

oh im sorry i didnt clarify the year, my mistake!

im swapping to a 4.6L from a 2000 GT same year as mine i have the GT fuel pump but i was wondering if i can just keep my original in, nd as for the fuel system? im not sure

thanks for the help so far!

Are you using the ecm from the car the motor came out of? If so then you'll need to use the pump out of the gt unless your v6 was a returnless system. Return style pumps and returnless ecms don't play well together.

yes im using the computer from the GT, im not a complete idiot when it comes to cars but the ecm is referred to as the computer also right?

im trying to find out what type of fuel system i have in my car but google isnt helping ><


EDIT: after reading for a bit i found out 99-04 have the returnless system so im assuming im in the clear?

just to be safe i would put the gt pump in. when your doing work on a car i always do everything properly, it may take longer than shortcuts, but i know that the work i did was correct.
