396 fuel pump

[Bill W.]

Does anyone know the actual date the 40248 fuel pump was last used on a 396 and a 40366 was used in its place ? I know #16120 had a 40248 . What should #17346 built May 12 have ? When I bought it 1980 it had a 40366 but it also had a Chevelle block in it at the time .

Bill,

Are you sure there was a change in fuel pumps for the 65 Corvette 396 during the production year?

My 1965 Chevrolet Parts Catalog (May 1965) lists GM # 6415962 as the GM part number for the 65 Corvette (396) fuel pump. The number listed in the 65 Corvette AIM is 6440248 (an AC part #) (See UPC L78, C1). Logic tells that GM # 6415962 = AC # 6440248 = AC # 40248 but I have no actual written evidence to prove it.

My 1966 & 1967 Chevrolet Parts Catalogs (Oct. 1965 & May 1967) also list GM part number 6415962 for the 65 Corvette (396) fuel pump as well as GM # 6416245 for the 66 Corvette (427) fuel pump. The number listed in the 1966 Corvette AIM is 6440366 (an AC part #)(See UPC L36, A2). I know that GM # 6416245 = AC # 40366 = AC # 6440366.

GM # 6415962 (AC # 40248, I assume) was still available over the counter until August 1967 as per Chevrolet Parts History and was replaced with GM # 6416245 (AC # 6440366 or 40366).

I have seen a photo of an original 66 Corvette (427) AC fuel pump that was stamped "AF 40366" (possibly owned by Wayne if I remember correctly) where the "AF" = January 1966. The "40248" AC pumps may or may not have a 2-letter date code stamped on them. I did a lot of research on AC fuel pumps with and without stamped date codes a few years ago.

Re: 396 fuel pump

Dave . Ok this question is for any one who has a 396 with "the " original fuel pump . What is the number of the pump 40248 or 40366 and your vin or date built .
Is there a way of dating a 40366 pump ?

Bill,

I will get back you on the 396 fuel pump part number that is on VIN 22161. I know it a bit later than yours but it was on the engine when we disassembled it in 2004.
