The rebuild kit I bought had one rubber valve, the main diaphram with rod, and the upper gasket. No o-rings (I do have those). Do I need both the rubber valves (part #7) to do the job or is it safe to reuse the best of the two inside? When I tried to post it with a pasted-in .jpg image of the pump diagram, it gave me this message: "You are not allowed to use that image extension on this community."

I bought a shelf-queen Nikki fuel pump which looks like it is from around 1971-2 and is probably for a B210 etc. It looks the same as my original one on the 1971 FairladyZ, except for the actuating arm and lower casting. I'm wondering, without tearing it apart, if the guts (diaphram, rubber valves, etc) are the same as the one off the Z. If they are, I might be able to save my original pump by swapping in the parts. Don't want to tear it apart if the guts won't interchange; could sell it to someone wanting a "new condition" B210 pump ... Anybody been into these pumps? Thanks!!
