Any advice on stiff fuel tap? is nos and works fine but i reckon this crappy fuel plus hot weather is causing stiff operation,any lubes out there that work?Ta Paul J

I'd be concerned that ethanol has made the seals swell........

My thoughts as well Mark,do use a so called Ethanol additive to annul effects of the stuff,have used the red rubber grease and seems effective,up to yet..
