    Subject: Re: in-line fuel filters - can you recommend any?
    From: Sacha <uuccio@gmail.com>
    Hi Guy What do you think of the idea of gluing aluminum welding flanges to the out side of the tank using two-part epoxy resin/glue or some other adhesive. Wou ld it work? Once the flanges are glued i could drill holes in the tank and then screw t he finger strainers/fuel drains in place. The flange for the fuel port could be cut so that it can sit lower down.

This makes it very difficult to secondarily reinforce, since it's h ard to get enough bond area for the reinforcement. Best would be to adhere a tapered 1/4" thick G-10 tapping plate where you want the exit, then cover t hat with about 10 plies of 8oz fiberglass, tapering or sequencing so that th e edges taper. This would give you a little less than 1/2" to tap into for the NPT finger strainers. (If you want to just glue a tapping plate ext ernally, you'll have to extend well onto the tank sidewall to get enough adh erence area to enable you do drill and tap the plate. Unfortunately the dril ling and/or tapping process usually pries the tapping plate off the tank any way. Been there...) > > Bulkhead fittings usually make you move well away from the edge/corner of t he tank, making you loose capacity.
