Fuel Pump Drain Plug Problem..maybe

[smuesse]

In another thread i wrote how my truck just started messing up. One of the suggestions is that my fram mounted fuel pump may be going bad. Saturday I installed the new design drain plug. I havnt drove it very much since then, maybe 80 miles. Now it wont hardly move and coughs up black smoke. My question is could the new design drain plug that has the long stem on it cause a problem when its put in the pump that would make it not pump fuel correctly?

I have the drain plug on order. I can't imagine it causing the problem. We will have to read on for others who have the new plug. It sure looks handy.

If you think the plug may be a problem, switch it back. I can't see how it would cause an issue since it's in the water seperator and not the pump itself.

It's not the drain plug unless you didn't get it tightened and then you'd have a huge leak. Have you checked your EGR valve? It's possibly stuck open and may need to be cleaned or replaced. Use Carb cleaner to clean it with NOT BRAKE CLEANER.

Yall are right. I found a layout of the pump and there is nothing for the drain plug to touch.
