When I originally got my truck the fuel heater had a little bit of a leak through the electrical connector on the outside. I cleaned it up, filled with JB weld and it quit leaking.
I figured that I should fix that permanently at some point, so I bought a 1/2" tap and pipe plug, and a new fuel filter. Several months passed and when I finally got around to removing the fuel filter, I forgot to keep the stainless plate as a spacer when reinstalling the brass thing that the fuel filter threads on to. I chucked it unfortunately, and the trash just got picked up this afternoon. (pic is from tech section of oilburners)
After doing this (and omitting the spacer) I noticed the truck was intermittently acting like it was getting some air in the fuel lines when running. Particularly after the truck was hot, I would occasionally get some light surging at idle, and intermittently, when under acceleration the truck would sometimes act like it all of a sudden had a lot of power, or the power was surging. No fuel leaks from the filter area however.
Today I took the filter off and started thinking about how I could have screwed up. I decided to look back at the tech forum thread and boom.. noticed I forgot this step.
I'm not sure how missing the spacer could cause air intrusion as the filter seals just fine, but obviously this is something I screwed up, and the truck did not do this before I changed the filter and installed the brass plug.
Thoughts? I'm guessing I need to find another fuel heater stainless spacer, or would a simple hardware store washer work?
Another thing, I do not have an o-ring on the brass filter thing. I definitely did not remove one so I guess it did not come with one. I note in pics of some new filter assemblies that there may be an o-ring here and there appears to be a notch in the threaded brass thing for an o-ring. (see link)
