filler tube on my '64 Bonneville is leaking, slow drip since last thursday after fill up to top, but has stopped at this point, O ring must have swelled back up!!! ran tank about half full for a few weeks which was a bad idea evidently!

have O ring coming & my question is can filler tube be removed without dropping tank ????? looks like it might come off enough to clean up & install new O ring, maybe!!

thanks for any info

If the tank aria looks like the rest of the car, it probably would not take an hour to remove tank. This would give you and opportunity to closely check for cracks in the tank or problem with vapor vents.
Or send out to tank/radiator shop for pressure test or repair. IMO.

Even a small fuel leak could be disastrous.

As I remember it can be changed without dropping it.You can look from under and see where it goes in.Tom

dropped tank to inspect inside it was clean like new !! amazing after 52 yrs. O ring change was rough being under body coating made filler tube removal hard had to clean at top & around tank opening & after cleaning it went back together a lot easier !! changed sending unit & of course new one was bad, it went to 1/4 mark only so Ames is sending another !! will be able to change without dropping tank which made my day !! will see next week maybe !!!

Are you 100% new sending unit is bad and not a gauge issue? You should be able to hook an ohm meter to it and see what it says on half, full, and empty to get a good idea if it's working. If it's putting out the right resistance, then there's a different issue.

the gauge is good checked As per instuctions, it pegs to full when tested & worked with old sending unit which was just all over the place & never steady,full to half to 3/4 back to full ect. it had a better ohm reading than the new one, Matt at Ames tested one @ 33+ ohms & sent it out to me , should get it in a few days !!!
