Does any one have any new ones to sell?? The parts stores raped me and i need multiples. Thanks!

Have you tried to order online from a parts warehouse? I think, but am not sure, that holley also uses teh same exact diaphram design in thier units. You might be able to order them from summit or jegs. Call them and see

If you find a source that doesn't want you to buy the WHOLE rebuild kit for $50 then please let me know. I'd like to get a couple extra for my dual TBI BBC project.
If I don't find out soon I might just look into an external regulator. Probably easier that way.
Holley's part number #512-1 , might try calling Summit Racing.

Rochester TB1220 all 5.0/5.7 bodies.

complete kit with reg diafram, o-rings, gaskets is $30 postage paid to you.

email me at oneandoutgonospam@msn.com for payment details/phone number.
