Good info thanks Jeff! As far as the insulator is concerned there doesn't appear to be any difference (naked eye), there may be a material difference....not sure.
I'm going to pick up the new toyota insulator tomorrow to see if there is $21 worth the difference.
there doesn't appear to be a good way to get the insulator off without cracking it. When I rebuilt my 2f I cracked the one that was on there as well.
I reassembled with HI-Tack in hopes of preserving the one that I bought to replace the first one that I cracked....no luck
Hopefully, I'll never have to change this one.
I'll be sure and post up if this fuel pump gives me any fits.
