davemfox Posted March 25, 2021 Posted March 25, 2021 (edited) Has anyone had a problem with the fuel tap bolts that hold it onto the underside of the tank leaking fuel (the brass coloured one in the below pic)? It's not a lot, more like a smear over a couple of minutes. It's only one bolt too, the other side is dry as is the rest of the fuel tap... Dave Edited March 25, 2021 by davemfox Quote
TonyGee Posted March 25, 2021 Posted March 25, 2021 i use 6mm dowty seals on mine, never had a leak yet Quote
eddiegsx Posted March 25, 2021 Posted March 25, 2021 Good call off tonygee with the dowty seals, I also put a smear of fuel resistant sealant on the threads just to make certain. Quote
Danm54 Posted March 25, 2021 Posted March 25, 2021 Is that a new fuel tap or just a very clean old one? Mine is leaking so needs a rebuild but if they're available new it might be a better option, price depending. Quote
davemfox Posted March 26, 2021 Author Posted March 26, 2021 Thanks guys Fuel resistant sealant - are we talking Loctite 243, or is there something else out there? @Danm54 it's a year old fuel tap. I went through a couple of rebuild kits and couldn't get it to stop leaking out of the on/res/pri tap bit. They're not cheap... Dave Quote

Dave Thanks Dave, that's where mine is leaking from, it's always been tricky to get it on res so I'll have a look for a new tap, get it sorted for the summer. Quote

Dave Any fuel resistant sealant should do the trick Dave, there's numerous ones on the market but I personally try to avoid the cheaper products if possible. The idea came to me a while back as a mate of mine had the same issues as you and it took him ages to find the leak, it was making its way down the bolt threads as it turned out. Quote
Captain Chaos Posted March 26, 2021 Posted March 26, 2021 that's why there are seals under the bolts from the factory Quote

Dave I use Blue Hylomar on screw threads on tanks exposed to petrol, e.g. those holding an aircraft cap to the tank. Quote
davemfox Posted April 21, 2021 Author Posted April 21, 2021 I got some M6 dowty seals and that looks to have cured it. Dave 1 Quote
Joseph Posted April 23, 2021 Posted April 23, 2021 Talking of rebuild kits, i am in the process of aiming for success in rebuilding mine. I took it apart, noting screw and spring postions etc But noticed that one of the membranes has a hole in it (as does the original one, but not expecting that, i'm wondering what orientation this hole must take ? Rather surprised that there is this hole at all but it looks standard ? Quote
