DIY air bleed screw for filter changes

[Gunfreak25]

Can a guy TEE in a petcock on the output side of the firewall filter where it goes to the injection pump? Sort of a cheap DIY air bleed valve to work in conjunction with the spin on filter and electric lift pump upgrade most of us do. Should work in theory correct? Being that is is the highest point in the system.

You could, but GM has provided a bleeder valve at the top of the filter housing already. On the top of the filter housing on the passenger side there is a black round valve. It has a cross shape on it. There is a small line coming out near it. When you change your filter, turn this valve counter clock wise about 1/2 turn. Then disconnect the big pink wire on your injector pump. Then crank the engine until fuel comes out of the little line by the valve. Then close the valve and reinstall the big pink wire. Then start the engine and let it idle a bit. Check for leaks.

To clarify I have a Napa spin on head with no air bleed provision. Sounds like it will work as intended though.

Then yes, A tee with a ball valve would work perfect.
