Gas Cap • The Dodge Challenger Message Board

by **Marcus** » 13 Aug 2001 23:57

Im having trouble installing my flip top gas cap.the one that says fuel on it.see I have 2 of them each are just a bit diffrent,one opens from left one from right,also one has a what seems to be a spacer,it just seems to stick out too far from car,and it doesn't seal the hole for sure,now my other one has no spacer on it but it does has the spring seal for the hole,but is not even close to fitting on the car at all,is there a special way to mount these caps,am I missing mounting stuff,maybe a install picture would help if anyone has it.

first off marcus one is a repro the other is real(the repro people made theirs open the wrong way i also heard the trim ring didnt fit right) i had one on my last challenger and i am trying to remember which way it opened im pretty sure it was toward the rear of the car, the trim ring should fit the opening and the 4 screws that mount it are inside hope this is a start ..will you let me know which is the real one and the fake i am looking for another flip-top for my current challenger

1969 Barracudas had a similar looking flip open top but it opened out the wrong way. Perhaps it is one of those.

What do you think of the gas cap that is flush with the body of the car? Does it look better than the traditional flip-top gas cap? I believe I have the one of those key lock gas caps that I got at an AL'S Auto Supplies store, now bought out buy Schucks Auto Parts, for a '78 Challenger, I think, surprisingly it fit better that the one that was on the car when I bought the car from my brother, which leaked when you filled the tank more than halfway because it did not seal the funnel properly. I never did get a chance to test the new cap with a full tank when the car began its long depressing, but not depressing because the car was falling apart from the lack of maintenance, which it wasn't, but because I could no longer drive the beautiful and most impressive car that I have ever driven, as you can imagine, mates.

joel...lol so what are you trying to say*my best jim carey impression*

by **Joel** » 16 Aug 2001 7:08

Was what I said funny? Well, I was trying to say is that the old cap that came with the car leaked when you went around a corner hard. The one that I replaced the crappy cap with fit very well, but did not get a chance to see if it sealed well enough to keep the gas from leaking out on a hard and sharp curve. Before I had a chance to test the new cap, the muck at the bottom of the tank began to stir up once again and I finally got sick of it and bought my dads Dodge Dakota until I could get a new tank and fix the entire front end. I want to have a 100% correct cap to use on my car, is the main point that I was getting at. Sorry to disappoint you Frank!

78 Challenger beautiful? (not) Why bother with a gas cap try a new car. Any Challenger over 74 shouldn't have the name badge!!!!!!

by **Marcus** » 17 Aug 2001 0:34

sorry guys this doesn't help me as much as I wanted it to,or as much as this board usually does,anyone else have info about the mounting process of the cap from the filler tube?

by **frank** » 17 Aug 2001 4:57

i c now joel... well marcus did you get any instructions with these caps or buy them used? i think i would try calling yr 1 or try your local dodge dealership and talk to some old mechanics or look for someone at a car show that has one explain your situation and ask to see thiers?

by **dave-r** » 17 Aug 2001 7:43

Marcus. It should be straight forward to mount the gas cap. It sounds to me like neither one is correct for your Challenger. The flip open top does not seal the filler tube. There is a small diameter screw on-cap when you lift the lid.

Like I said. At least one of your caps will be from a 1969 'cuda and will not fit. I suspect the other is wrong too as it should be straight forward and obvious how it fits.

The stainless steel trim ring goes over the opening first. Then the flip cap just offers up to the opening and attaches with four sheet metal screws. The screw-in cap then fits over the filler hole and you shut the lid.

I can't remember which way the damn thing opens on a Challenger. I think the hinge is on the left but as this is from memory you had better wait until I get home to check unless someone else can do that first.

by **dave-r** » 17 Aug 2001 7:45

Changed my mind. I think it opens to the right!

I will have to look!

by **jen** » 17 Aug 2001 13:14

It opens to the right.

by **dave-r** » 17 Aug 2001 13:25

Oh that was it! I was confused because I dress to the left!

How come you can get things to work and I just get nothing. The ISP must prefer blondes!

Ah so my memory was right! first time for everything.i must have missed that marcus's filler tube has trouble sealing is this right marcus? excellent pics jen&dave.

by **dave-r** » 20 Aug 2001 7:25

The screw-on filler neck cap in the photo above is not the original one. My mate Linda managed to loose the original one first time she filled up....

What can I say "perfect responces",pictures tell 1,000 words.I have it all figured now,I have the inner extention but don't have the chrome trim ring.and I didn't know that this didn't seal off the tube,now I see this is just a fancy cover to a small cap,thanks all so much for your help.once again this site helps out big.

by **dodgefreak** » 28 Mar 2005 11:24

maybe the same problem here? any know how to fix this?
there was a small ring included, but how can i "lower" the complete cap? or is this normal? also : it does'nt seal the fuel tank...

all tips are welcome!

by **dave-r** » 28 Mar 2005 13:10

Don't know why yours is sticking out so much but see the previous pages of this thread for the tank sealing thing. There is a small inner cap!

by **dodgefreak** » 28 Mar 2005 17:45

dave, the sealing of the tank is'nt the biggest problem, many ways to fix that, but the sticking out problem... i'll email yearone to day, maybe they have a solution...

by **dave-r** » 28 Mar 2005 21:05

If I get a chance tomorrow i will take a few photos/measurements of mine so you can compare.

You also need the steel ring to go around the sheet metal opening.

by **dave-r** » 29 Mar 2005 20:41

Here is a photo of my original flip cap and also a side view showing how much better it looks with the trim ring in place. Sorry the car is not here to show it fitted.

I think looking at yours now that yours is OK. It just needs the trim ring.

Is the fuel filler tube correctly mounted? The flange on the tube is supposed be placed on the inside of the body (if I have understood it correctly....).

(It will not add/reduce many inches but it is maybe enough!?)

thanx dave for the reliefing pictures... will mount the trim ring tomorrow and take some pics... i looked so weird without the trim ring...

thanx again!

The problem (if it was sticking out too much) might have been due to the rear quarter being a replacement.
