Reader Tom from Boise, ID sent me this fix for a failed RC24/26 fuel pump. The 2d-gen fuel pump is unique in that it has 90-degree curved inlet & outlet pipes, necessary to allow the fuel lines to clear the coolant overflow tank. The later VFRs are mounted in a more accessible location, allowing straight inlet/outlets. Trouble is, the curved-piped pumps are NLA from Honda and not available on the aftermarket.
Tom's solution is to simply source some 3/8-inch (10mm) 90-degree rubber fittings and clamp everything in place. I've accomplished the same thing with shortened brass 90-degree fittings, but the rubber fittings are a simpler solution. This fix will allow use of the later OEM pumps or their aftermarket replacements. NOTE: the later pump wiring is reversed from the earlier connectors. You'll need to splice the original connector onto the newer style pump wiring.

Tom's initial problem was fuel spewing from the crimped metal seam in the middle of the pump. He opened the crimp and disassembled the pump, locating a failed o-ring which he thinks may fix the leaking. Tom elected to go with the new pump, but replacing this gasket might be another approach.
