Reply to "Exhaust"

I kept smelling gas from the MG TD replica I'm working on. Tracked it to the filler cap, which was ill-fitting. Closer inspection revealed it was ovoid. Pulled the tank, drained it, let it sit upside down in the sunshine for a couple of weeks, then blew fresh air through it with my shop vac for several hours. Applied my trusty tailpipe expander, it opened up cracks in the weld. Ordered a filler neck that looked like it would fit from Summit Racing. Cut the old neck at the weld point, it was all cold joint and fell apart. That's what you get when you try to weld a tank filled with water. Fit the new neck to the tank and brazed it in. Tricky because it's  much thicker than the sheet metal. Not my prettiest work, but it's sealed and looks okay with paint applied. Added a vent because the new cap isn't vented. Haven't got it installed because I'm still working on patching and sealing the firewall.IMG_20200728_104930933_HDRIMG_20200728_124918398IMG_20200728_132225104IMG_20200728_174027842_HDRIMG_20200729_070345218IMG_20200729_115847329_HDR
