Low Fuel Pressure

Number 2 is definitely vapor. I can't see where the other lines go but i would suspect the one with the repair is the feed. It will be larger line than the return usually. As you can see, these lines are plastic and cannot be pinched. You will have to find another way. Our fuel pressure kits come with a lot of adapters than can usually be used.

OK, that's not good news.

We have to do some electrical tests now to make sure we are not losing any current to the pump. You are going to need a digital voltmeter and some long jumper wires so we can do a voltage drop test.

You need a digital voltmeter that read in tenths of a volt and jumper wires that will reach the battery in one direction and the tank in the other direction.

You can watch this video to learn how to do voltage drop testing. At the pump, the gray wire is the power feed and the larger black wire is the ground for the pump.
