Drdialtone Posted February 28, 2011 Report Posted February 28, 2011 My 47 Special Deluxe Club Coupe appears to have a slow leak at the bottom of the gas tank (around the drain plug). Questions: 1 is this just a sealant fix? 2 can a gas tank be revitalized? 3 are the gas tanks advertised on eBay a better route? My P15 is a driver, so I'm not too much concerned about original equipment if a new tank is better. Also, the gas gauge is always on full. Bad sending unit perhaps? Thanks! Quote
1940plymouth Posted February 28, 2011 Report Posted February 28, 2011 I have used the two part epoxy on my gas tank, so far so good Quote
Young Ed Posted February 28, 2011 Report Posted February 28, 2011 I had my tank sealed by gas tank renu. If you feel you can handle a little bit of improvising to make it fit I'd say a new one would be cheaper for you. Quote
BobT-47P15 Posted February 28, 2011 Report Posted February 28, 2011 I personally don't care for those plain looking kind of square tanks made by one company. (Tanks, Inc maybe) They work OK, but don't look close to original. I think there is some other outfit that makes a more original looking tank, but it may cost more. I also wonder on occasion what later model tanks might work (Perhaps with some modification) in the old Mopars. I doubt anyone has been inclined to research this. Quote

No they do not look like the OEM tanks Bob, but they are well made, install very easily, have the applicable holes for the sender, and no need for that ferule in the gas line at the tank. These tanks have a roll over valve that also acts as an air valve too. The tanks do not look bad, they are new, either in SS or metal, sure beats a rusty cruddy old tank, and who sees it unless you bend over to have a looksy.... Quote
suntennis Posted February 28, 2011 Report Posted February 28, 2011 If the leak is from the the drain plug, gas can spread out about the plug as opposed to just dripping from the plug. I had this problem so I tightened the plug which made it leak more. My problem was the gasket on the drain plug and was fixed by making one out of some good gasket material. To drain the tank, I used a large container and loosened the plug only enough to drain some gas and drained only about two gallons at a time unti.l empty. Quote
Drdialtone Posted February 28, 2011 Author Report Posted February 28, 2011 Thanks, I am inclined to get the new one since I have no idea how the "inside" of the existing tank is... could have 64 years of crud, right? And SS is the better choice? Quote
Drdialtone Posted February 28, 2011 Author Report Posted February 28, 2011 Thanks for the advice on the drain plug gasket... from your description, I have the same symptoms - not a drop but rather an ooze around the plug. Quote
Drdialtone Posted February 28, 2011 Author Report Posted February 28, 2011 Oh, and any advice on the gas gauge? Maybe the float unit is stuck at the top? Or perhaps this is electrical? Quote
Andydodge Posted February 28, 2011 Report Posted February 28, 2011 If the guage is always on full maybe the float is either holed or the cork is RS, I'd check the sender unit first for anything that doesn't look right, also most radiator shops should be able to repair/pressure test the fuel tank........andyd Quote
busycoupe Posted February 28, 2011 Report Posted February 28, 2011 I had my gas tank repaired at a local radiator shop. Mine was actually cracked near the top corner. He kept it over a week to let it air out before working on it, but it came out great. He cleaned it out and tested it when done. It was kind of pricey, $200, but it was a substantial repair; and I still have the original tank. Dave Quote
oldodge41 Posted February 28, 2011 Report Posted February 28, 2011 At some point in time before I bought my car someone had made a repair around the drain plug with what appears to be an epoxy type product. When I put gas in it oozed as well. I was going to remove the epoxy and redo it but Dad suggested making a new gasket for the plug first. It worked and has never been a problem since. Quote
E.L Lane's 48 Posted March 1, 2011 Report Posted March 1, 2011 Try these links. This is the route I went and I am pretty satisfied with the result. Easy install. http://cgi.ebay.com/ebaymotors/Universal-Alloy-Steel-Truck-Gas-Fuel-Tank-street-rod-_W0QQcmdZViewItemQQhashZitem53dd64e754QQitemZ360196663124QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories http://cgi.ebay.com/ebaymotors/45-46-47-48-DODGE-CHRYSLER-PLYMOUTH-GAS-SENDING-UNIT-_W0QQcmdZViewItemQQhashZitem4cf379b1f9QQitemZ330502353401QQptZVintageQ5fCarQ5fTruckQ5fPartsQ5fAccessories Ask the seller of the tank for a 60 degree filler tube instead of the 45 degree. It is required for the correct fitment of tank. The sending unit works with the original guage. Quote
Drdialtone Posted March 1, 2011 Author Report Posted March 1, 2011 Thanks! Buying new may be the best course; one less thing to fiddle with I suppose. Appreciate the links! Quote
BobT-47P15 Posted March 1, 2011 Report Posted March 1, 2011 That new tank sending unit mentioned by E L Lane (on ebay) sounds like a respectable deal. If I didn't have a fairly new sender, I'd be interested in that one. Along with the possible bad float, the windings and conacts inside get worn on the originals. Quote
