I’m building a pair of fiberglass wing tanks and looking for the fuel tank fittings. Have searched Spruce, Wag, Amazon, Summit Racing, etc. with too many options. Anyone have specific advice on fittings/kits/attachments for fiberglass wing tanks that they have used?
There are various ways of doing that, but I cut out some 1/4" aluminum plate (same thickness as the tank walls), drilled and tapped an NPT hole in it, and sandwiched the plate in a matching cutout in the tank walls, then put several layers of fiberglass cloth over the plate and walls inside and out to make it part of the tank wall (or bottom). Cover the NPT hole before glassing with electrical tape to keep epoxy out of the threads. That worked fine for me. There are other store-bought solutions that have o-rings and such, but this was cheap, quick, and required no shipping charges.
While we're on the subject, hopefully you used some kind of epoxy on the internal glass that is impervious to ethanol so you can burn auto fuel. The commonly used West epoxy is supposed to be fuel-proof, and there are vinylesters that are also (but they sure do stink up the shop!). I can send some part numbers later, if you'd like....
