no the guy i bought it from said he just did that before i got it but should do it so i will know myself put new fuel filter in it the new lift pump was to run between 5 to 9 lbs thats when i was told bout the 15lb one hurting my injection pump

when you replace it make sure you do with AC Delco. dont get anyone else, i put one in my white truck and it lasted 2 weeks, the ac delco still works.

"at idle should be around 9 to 12 psi
normal driving 7 to 9 psi
foot to the floor 3.5 to 6 psi"
