Gas Cap for 1989 MoHo

[noiva]

My gas cap needs replacing. Does anyone know where to buy one that will match whatever Airstream was using in 1989? Should I just take the old one to my friendly NAPA store, or is there a specific one I should use?

Thanks for any help,

You can find replacements at PepBoys....they seem to have a large selection of replacement caps with differing thread depths, etc. I think they even have one that is made of metal and matches the original.

I replaced mine after leaving the original on the bumper once after a fill up.

Steve,

Thanks so much! That's even closer for me than NAPA. I'll get that done this weekend. I'm certain I'm actually evaporating a fairly large amount of gas just sitting in the heat. Has anyone else experienced that? Hopefully, the new cap will not only replace my broken one, but slow down the evaporation. My old one works, but is coming apart with each removal, and the rubber O-ring is cracked. Again, thanks.

Tim, is it the screw-on type, or the single cam, push-and-twist type?

It's the screw-on type that clicks when it bottoms on the threads. In other words, it's a two-part construction.

Pretty simple screw in type on my rig. They actually are vented. Take the old one in with you to compare the threads.
