delivered the honda yesterday. i think that it may have been pure cooincidence that these both failed around the same time.
the truck had 177k. before he was stationed here, he had been stationed at 1/2 dozen places around the country. seems just age on that one.
the honda uses a returnless fuel system. the pressure regulator is mounted on the fuelpump module inside the fuel tank. upon removing that yesterday, i could see the little plastic clip that holds the regulator in place had cracked, allowing the regulator to shift just enough to displace the rubber o-ring, causing it to leak, thus dropping pressure. the honda runs on 40-47psi. this car had 39psi when started, and slowly dropped to 30psi. funny thins is that it felt fine while driving it.
installed the new fuelpump module(BTW....if any of you in the field get one of these, they're cheaper from honda, and they're the entire module assembly, not just the pump.), and pressure came right back up to 45psi.
