Fuel Pump

[Scary John]

Hello guys, new on here asking for a little help with a fuel pump.
I have a 1963 Convertible and the fuel pump was dead. I ordered a replacement rebuilt pump but it doesn't have the dimple on the side for the retaining bolt to locate into. Does anyone have a pump that they could measure from the base of the housing to the dimple for me? No I can't measure the old one as one of my friends has thrown it in the trash two weeks ago and it's long gone. I'm thinking that if I locate it too far in the pushrod will over stretch the diaphragms
Thanks in advance

"REBUILT" --- I'm not aware of any rebuilts, just new at this point in time.

Recently someone else bought a "new" fuel pump without the retaining "dimple". It's a defect.

If you purchased the pump from a Corvair vendor they will replace it. I'd request a replacement since yours is not correct.

Likely a garbage pump from Rock Auto. Have seen a few of these in photos. It is kind of hard to drill a cone shaped hole anyway. Send it back and buy a real pump from a Corvair specific vendor or convert to electric.
