Default 87 Renix 4.0 fuel pressure question

So guys, I just got a quick question. So my 87 loses pressure at the fuel rail after it sits for awhile. I think the check valve is fine and the regulator is fine, but I think the injectors might be leaking. Anyways, I'm thinking about buying fuel injectors and want to make sure I need to buy some before I do. I am going to test to see if they're leaking onto paper towles on Thursday.



My original question is that the fuel rail should have pressure to it even after the jeep has been sitting for a few hours, right? To keep it "primed."

Yep.

Contact Programbo here on Cherokee Forum and get some Volvo 746 injectors.

I'm already talking to someone about buying them, I was just trying to make sure that my understanding was right. I'll see what kind he has, then I might hit up Programbo to look at his. Thanks.
