YKC sierra roadster fuel tank & sender seal
Hi guys, my YKC Sierra based raodster car continues to improve, new clutch, new carb and now I find, if not before, the fuel sender sensor fitting to the tank is leaking. There was always a slight whiff of fuel about the car but having got rid of the leaky Weber carb we have traced a leak now from the fuel tank sender.
I have tried to seal it with Mylomar, a new cork gasket, a new butyl rubber gasket but it still leaks. Not having built the car I have no idea where the tank came from, whether it was a YKC adapted part or whether the builder obtained his own. In the YKC generic build manual it says it is an escort tank, earlier posts suggest it is an escort van tank, whatever. I have tried to reseal the sender without removing the tank. I have examined the tank in situ with torch and a mirror to assess the appearance. I do not like the appearance of what I can see. The sender flange on the tank appears to have been brazed into place before fitting as does the filler pipe neck from the tank to the filler cap and inlet. After brazing, both the flange and the filler pipe appear to have been "finished" with a good dose of resin filler to smooth them off. This makes me suspect a less than satisfactory approach to the finish of this item.
Can anyone answer the following questions please a. If you built your car, was the tank of a similar cobbled up finish if it was a YKC item? b. If you fitted the tank yourself, was it fitted before the rear tub? c. Has anyone had the same problem, I know other types of roadster have had a similar leak. If you have, how did you fix it? d. Has anyone removed a tank post construction? e. The only simple way I can see out of this is to clean up the flange with the sender in place, degrease, grit paper lightly and cover the whole assembly in a good dollop of resin paste, post Chernobyl fashion?(this may seal the joint but potentially renders the sender inaccessible)
Any other suggestions welcome, thanks for looking, Patrick
