I'm curious about this one myself. I *DO* get a hiss when I open the fuel cap.
It appears that I've solved my problem. At least the symptoms (stalling) have gone away with a PMD replacement. I bought the D-Tech one from pmdcable.com along with extension and heatsink, mounting it behind the...
Okay, read about 10 times, I understand it all in theory now. I will do the PMD relocation and fuel filter replacement next week and will do fuel pressure test like you say. I might also try the fuel pressure test described in that thread regarding highway speed psi, idle psi, hard acceleration...
When you say fuel cap, do you literally mean the cap on the fuel tank? Or do you mean the cap on the fuel filter? The fuel filter cap doesn't mention diesel, but I can't see how it would be the wrong one. The fuel tank cap does say "diesel only" and yes I get a vacuum-sucking sound when I remove...
Wow okay I have some work ahead of me. Thank you very much for taking the time to assist with another newb. I will put in an order for DTech from pmdcable.com tomorrow and skip the veggie mechanic appointment. I have a friend who is pretty handy with auto repair, maybe I can lean on him for a hand.
Yeah, I'm figuring that out now. I'm switching to B5 as of today. As an aside, are any newer trucks (2004+) just great for B99?
Your recommendations sound like something I would need to learn to do. How do I check the fuel pressure out of the drain and at the IP inlet line?
It looks like i need to take of the manifold to get access to it. Am I right there? The whole PMD area is really buried. Do you know of any threads on this forum that are step-by-step replacements?
I've spent a couple hours on the forums here, learning about PMDs and I think that's my problem. I'm not mechanically inclined, but I am good with tools (carpentry mostly) and generally fearless. I've taken the truck into a diesel mechanic (Parkrose Truck and Auto in Portland Oregon) and they...
