Fuel pumps started leaking badly around O-rings when I adjusted fuel pressure up to 37psi (engine not running). Pooled up in fuselage. Need to fix before I try running again. Gas is cheap, but not that cheap. I'll try copper washers on the pressure (output) side instead of the o-rings. > <hdhnppaldlddbemj.jpg> > Yes, I know, not pretty.
