Hi,

I have a 71 impala with a 400 small block, and I'm trying to locate a fuel pump.

The problem is that the fuel pump on the car is not like the ones availble from the local parts store.

The one on the car has 2 imputs with a larger housing, like a marine fuel pump. I think one of the lines is recovery return. My local Chevy dealer only shows parts as far back as 76.

I could put a regular pump on it but then I have an extra line to contend with.

Has anyone seen one of these before, and if so where can one be bought?

Thanks for all replies.

^^^^ Check this link i think this is the pump your looking for. if you try to find it another parts store i put it in as a 1970 camaro with a 5.7L 350 with a 4bbl carb.

 

my 1970 Monte carlo has the same thing.
though at some point the previous owners simply put a bolt on the return line to cap it off.
in 19 yrs Ive had the car- its not been a problem.
I think it was some return line for unused fuel or something.

 

Twizzle12,

That's it exactly. I searched the napaonline as well as my local NAPA store and they had never seen one. Thanks.

rbarrious,

I had a 1978 Mark Twain boat with a 3L 4 cylinder GM engine that had a similar fuel pump. I thought it was used because if the diaphram failed then the bildge wounldn't fill up withfuel.

This car isa driver and I like to carry a few spare parts, so I wanted to able locate one. I figuired I could buy any Chevy small block pump and make it work. I'm just picking about having correct parts.

Thanks again for all replies.
