RE: [Chevelle-List] Fuel pump BE CAREFUL, READ THIS
Replies to this message are sent to The Chevelle Mailing List I found out that SBC pumps do not work on a BBC. When installing the SBC pump using the BBC fuel pump pushrod I noted that the pump would fit flat against the engine with no tension from the pushrod. Normally you cannot hold the pump totally against the block without using a wrench to tighten it to there. The arm on the BBC pump sticks into the block a little farther than the SB pump. I speculate that it would make a lot of noise for sure, probably would work but not very well for a short time, and eventually wreck the cam lobe or pump or both.

Replies to this message are sent to The Chevelle Mailing List Be careful!! BBC and SBC fuel pumps are totaly different. They are by no means interchangible. Dammage will result. do not interchange them. Sean From: Jim R Hunter [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: [Chevelle-List] Fuel pump identification?

Dale McIntosh ACES #1709/TC #92 Gold 67 SS/67 Elky http://www.dalesplace.com Does anyone know if fuel pumps have part numbers stamped on them and if I could find/read one while the pump is still on the car? The reason I need to know is this: I'm not sure what year/style pump I currently have, so before I pull my current fuel pump off to replace it I want to have the correct replacement on hand. The reason for the mystery is this: I have a 69 SS396 with a '72 402 engine a 69 Q-jet in it. Also, instead of a 3-piece pump to carburetor line, I have a single piece pump-to-carburetor fuel line. After looking at the pump photos in an older Year One catalog, my pump visually appears to have a shape like the 1971-1972 big block fuel pump that they sell (as opposed to the shape of the 1969 big block fuel pump that they sell). So, I'm leaning towards ordering a 1971-1972 pump, but before I do so I'm wondering if I could expect to find a decodable ID number that would be visible to me if I were to scrape off what looks like decades worth of grease and grime on the pump while it is on the car. As always, thanks in advance for all the help I get on this list!
