Hello, New to the forum and trying to correct some issues from past owners on a Corvette I bought. It's a 70 350/350. All stock and numbers match.

It had an electric fuel pump with rubber lines and I want to go back stock. I ordered a pump to carb hard line and then a fuel pump. The hard line is made to attach to the front of the pump but the fuel outlet on the pump faces to the rear. Which part is wrong?

Also, it looks like the pump should have a feed line from the tank and a return line, is that correct?

This seems like it should be very simple but I'm having a heck of a time getting the right parts that will match up and be correct. I greatly appreciate any help on this.

Kind of went through this while changing my BB pump

68 and 69 pumps had the outlet pointing towards the front. (not sure about a return but I don't think so)

70-76 pointed towards the rear (with return line)

LT1 pumps pointed to the front (no return line)

I think your missing this little brass fitting.

The 70 assembly instruction manual (AIM) will show you everything you need and list the old, original part numbers.

Thank you very much for the info and the fast responses. From what you've told me I realize the first piece I got (pump to carb line) was wrong. Then I tried matching the pump to that and got further away from correct. New line is on the way now and I'll have this car going soon.

Where can I get an assembly instruction manual? It sounds like a great tool to have.

Thanks again

I got mine from Greg's Automotive in Santa Ynez, CA

Several of the supporting vendors here sell them.

Assembly Instruction Manual, which was the reference document for the Corvette assembly factory workers. Make sure you get one for your year. It takes a bit of getting used to the way the book is laid out (as needed for the various work stations in the plant). But, once you understand it, it becomes a VERY useful tool (indispensible, IMO).

Be aware that only the parts assembled at the vehicle factory are shown in detail in the AIM. Sub-assemblies (like door assemblies, steering sub-assemblies, engines, transmissions) are only designated by their sub-assembly P/N and no detail for that sub is shown in the AIM. But, for what it is, it's a wonderful asset to the DIY C3 owner.

Hi sdho,
WELCOME!
1970 350/350 NICE!
In addition to the Assembly Manual you might want to consider buying the GM 1970 Chassis Service Manual, too. It contains very different information than the AIM, but is very helpful too.
Regards,
Alan
