I'd solve the failed leak down and replace the twisted line.

 

We want to help you, but you need to do what we are telling you
. it will be cheaper in the long run

 

I'm going to replace the fuel pressure regulator today and clean my EGR valve and give it a gasket with the mesh screen.

 

Whats the pricing and names of those fuel line pieces?

 

I`m done

 

For what? I'm doing all I can with what I can afford. What your telling me, I'm doing, along with the others I mentioned. I'm doing the best I can.

 

What was the fuel pressure and leak down reading at the filter?

 

Turn key on, 60psi. turn key off, doesn't hold, drops to 20psi within 10 seconds. What year and models fuel pressure regulators are interchangeable for my 95 jimmy?

 

Those results mean the fuel pump isn't performing up to specs. The pump can't supply enough fuel to rev the engine.

 

Could this be my problem? It's the fuel line from the fuel pump to fuel filter and it's twisted
