Is there a site out there or has anyone create a list that they can share? I’ve done some searching but haven’t found a list. Would be nice to have a list in hand when I go to a swap meet.
Thanks,

the complete fuel pump assembly is group 3.900
i checked the GMpartWiki for the years 47-53 which is the generation of trucks i have.
i found only 3 pumps listed, AC-429 -9798 and -9832 for that year range on trucks:
Straight in/out connections:
37-51 ALL, (body casting no. 1523089) (AC.429). 1523429
newer Angle in/out connections for use retroactively on older models:
37-54 ALL, 55 COMM. UTIL. (1st Ser.) (angle outlet)(AC-9798 or AC-9832) 5592627
with
37-51 ALL, ELBOW, inverted flared tube (5/16-20 deg.) 3707972*
*NOTE: This special 20 deg. angle fitting provides for installations of part 5592627 on 1937-51 models without bending the fuel lines. | | | | | Joined: Aug 2018 Posts: 1,004 'Bolter | | 'Bolter Joined: Aug 2018 Posts: 1,004 | I’d love to see an example of that special 20 degree fitting so that you didn’t have to bend the fuel lines with the newer angled pump
Was that part every used in practice or did everyone just bend the fuel lines?

part 3707972 explicitly to NOT bend the fuel lines is listed in the 1957 parts book.
37-51 ALL, ELBOW, inverted flared tube (5/16-20 deg.) 3707972*
*NOTE: This special 20 deg. angle fitting provides for installations of part 5592627 on 1937-51 models without bending the fuel lines.
edit: i have also found this special elbow listed in the 1954 parts book
wonder why a GM service bulletin would suggest to bend the fuel lines if a special part was made so that you didn't have to bend the fuel lines | | | | | Joined: May 2022 Posts: 70 'Bolter | | 'Bolter Joined: May 2022 Posts: 70 | All,
Great information! Just what I was seeking to learn.
Bouymaker - special thanks for the photos. I too have seen a fair amount of “fake NOS” in original boxes when hunting for Henry’s flathead V8 parts but I know what I’m looking for. The Chevy realm is new to me. The photos are a tremendous help.
Thanks,
