mine runs fine at idle but dies under load

 

stll having same issue i replaced the ip and she still dies under load idk what else to do i guess try the tsv

 

Replaced the tank selector valve I'm out of ideas please help

 

Have you installed clear fuel lines from the pump to the filter? Look at the fuel pump it has a weep hole, see if it's leaking.

 

i have narrowed it down it's between the valve and the pickup

 

im having the same exact problem with my 92 runs and idles for days but dies when u drive it. im stumped. new orings and rubber lines and the return caps. any ideas? if one injecvtor leaks will it cause it to die or miss?

 

best advice i have is buy a electric fuel pump from the auto parts store and work your way down the truck conecting it in different places when you connect it hit the schrader valve on the fuel filter and check for air you can narrow it down very easy that way my air leak was the fuel pickup somewhere its sucking air so im gonna pressure test it and find out

when you connect the electric pump you need to pull fuel from an alternate source other than the tank
