Anybody has any ideas where I can find the rubber sealer/grommet for the filler neck in the plastic gas tank? This is for an 87 D150

 

Yeah, good luck with that. I pulled my tank last summer and the grommet was crap on the outside top. Dry rotted as hell. Without that bubble lip on the outside, it becomes a dirt and crud collector. After searching the parts stores, internet, and probably 30 trucks in the boneyard with every one of them in the same condition, I gave up and bought an extra one from the junkyard and fabbed it. I took the nice inside tapered part and cut it off with some extra to form a male end to go into the old one backwards. IMO the tapered part should have been on the outside as well from the factory cause the tapered cone will shed dirt and water better. Anyway, after cutting the ugly part off the original, I inverted the extra one and permatex'd them together to seal it. Ugly but functional.

hey guys,i got my tank grommet from the dealer for my 93 d150.
it should be still be availible,if the dealer does not have one in stock they can tell you what other dealer has it.

 

Well, between what to Autozone guy told me and everything I read about what a challenge it can be to find one of these, I found one at my local dealer for $18.

 

I don't know if I'm more surprised to know that the dealer has it in stock or more surprised that it's less than fifty bucks. In any case, I need to visit the dealer too. Thanks Aje...
