One of those lines is likely the fuel pressure regulator line, which returns fuel to the gas tank if the pressure is too high. The incoming fuel line should feed into the Throttle Body Injector.

If the engine does not start, after changing the fuel filter, focus on the Ignition Control Module.

OK. Will do.

OK. Back on the job. Put on new fuel filter. Not any better. Please look at the two pics I have posted. Shouldn't I be gettting fuel at that point? As you can see, there is not a drop. Could I have a blocked fuel line?Attachment 46524Attachment 46525

You definitely should have fuel at that point. Try disconnecting the line at the filter and blowing compressed air through it.

TX, is there anything between the filter and the point I show in the photo where the fuel line enters the injector body (or whatever it's called)? Is that just one line all the way, or there is another part that I cannot see?

It should be one line all the way.

OK. I'll finally have some time on Saturday. I'm going to blow out the fuel line to the tank, and then see what I'm getting out of that line.

I seem to be getting a good flow of fuel all the way to the top of the filter. I've posted a pic of the where two lines enter the carb/f-inj. Which one is the main fuel line, the one on the left or right? The one on the right is a little larger.

One is likely the fuel pressure regulator return line to the gas tank. My guess is that the one on the right is the incoming line, but you need to see which one goes to the gas tank. Why don't you disconnect the fuel line at the filter and blow compressed air forward, after taking a rag and covering the lines. This should answer your question.

Will do.

Giving up on it, Tex. Going to have it towed to my mechanic. I'll let you know what it turns out to be.

Thank you.

Turned out to be the fuel injector. I considered replacing that but decided it was a little beyond what I wanted to do. Thanks for your advice. It was good to have.

Made the ultimate repair. Sold the truck!
