Hi All,
Can anyone tell me what the fuel pressure should be at the fuel rail?
I have an ajustable releif valve and want to set it up properly.

Thanks Bill

A quick google search of the Bosch L-Jetronic Injection system gives this:



35 +/- 1.4 psi.

This is for a Porsche, but I think the Ford 2.9 V6 Efi system is pretty much the same.
The fuel pump is similar anyway. wink
