I have a replacement fuel pump as at the time could not find a "rebuild kit" for the 1972 FJ40. It was leaking like a sieve when I started it up. Assume bad diaphragm. Someone also told be to change my oil as the fuel can leak back into the case through the fuel pump access.
So, here is what I got. Can't find a Youtube "how to rebuild" for the FJ40. I can now find an original Toyota diaphragm but unsure how to release the diaphragm "T" stem from the metal collar and rubber lower seal. See pictures below. No tear or hole in the diaphragm but there is contamination in the lower part of the chamber meaning something coming down through the diaphragm or something coming in from the case fuel pump access hole.
Below is the fuel pump and a fuel pump rebuild kit. I can only find the original Toyota OEM diaphragm with the "T" stem. None of the "other" rebuild components.
