Hello  good people may i have some comments about the best gas cap for my clipper Spence

I do not know if this is the answer you are looking for, but in my recent study on trying to resolve my running problem.  The manual from Dodge indicates that the fuel system requires a non-vented gas cap.  If this is true it seems that the replacement air in the tank must be brought in to the tank through the emission canister. otherwise there would be a vacuum in the gas tank and the fuel pump would not be able to pull gas from the tank.  what'd think.

dear kj   my gaS CAP INFORMATION IS WHEN YOU FILL THE TANK PUT IT BACK ON . HOPEFULLY SOME OF THE HIGHLY SKILLED MECHINICS WILL RESPOND TO OUR INQUIRIES . EARTHLING CALLING OUTER SPACE , GAS CAP SPECIALIST COME IN PLEASE.

From my experience, the vented cap works best.  However, if you have to pass the emissions test in your zip code area, you'll probably have to have a non-vented cap to get through that.  Good Luck

The evap. canister, under the pass. side is supposed to allow air into the gas tank through the dome on top of the tank.  Air in, nothing out.  If it's working properly, which allows the use of a non-vented cap.  In some cases, mine for one, the one way feature of the dome failed and allowed gas to flow up to the canister and onto the ground after filling the tank.  Since I was in the desert at the time, I clamped off the line to the canister and unscrewed the cap enough to allow the tank to vent.  Some people plug the canister line and use a vented gas cap then switch over when it's time to smog.  I'm not suggesting that anyone do this, since it solves the problem of venting gas tanks. but some people do.

Spence. Look in the tips & tricks forum archives.Bottom of page one. One of the pages has a list of part numbers for many items. The gas cap might be listed.

OK Bob,

Are you following me around?  Holy smokes, Our Clippers are falling apart at the same rate!

My gas cap key stopped working three months ago, so I took the old cap to Hawley's (A local auto parts store for those non Washington State types) and it was replaced with an almost identical new cap.

brand new clipper locking fuel cap. Advance auto stores, $15.00, Made by STANT, works great.

Hiyya Bob.   I know you follow posts, so you know I had a ton of venting issues too.  Like an idiot, I threw my charcoal canister away and plugged the line, after it dumped fuel alla time filling up.... which turned out to just be a kinked vent line in the filler neck.  The regular (unvented) caps allowed all kinds of pressure to build in my tank, and I'd get a huge "whoosh" every time I took the cap off.  I never could find a "vented" cap, so I just drilled a tiny 1/16" hole through the cap.... end of problem.
