Hey guys, does anyone know what the correct part number would be for a 2 line pump in a 70 W30? One line in, 1 return. It is one of the last pieces i need for my correct build. I cant seem to find anything online with the correct part number so hopefully someone can help me out. I am looking to purchase a NOS pump with the correct number on it so if anyone has one, please message me. Thanks!

 

40736

 

I believe that 40736 is an aftermarket part number.

The original factory-installed AC Delco pump for 1970 W-30s was 6440712. But good luck finding one.

 

The OEM pumps are not ethanol compatible. Carter makes an Olds pump that is compatible It has the return line and I have it on my 66 442 and it works great.

For what it's worth, the pump pictured in your link does not have the same inlet and outlet configuration as the original for a 1970 W-30. Maybe it's correct for '66, and maybe it can be made to work for a '70, but the connections will need modification.

 

Yes, the correct part number that i need is 40712. If anyone has one, please let me know. Thanks so much!
