Default Fuel Pump

I have to replace my fuel pump on my 69 350/350. At the bottom of my pump, there are 3 fittings, supply, output and RETURN. I think the return is an emission device or maybe at one point it was a California vett with all the other devices removed. All the pumps I find on line only have two fittings, supply and output. 1. Do I need the 1/4 in return? 2. If I do need it where, can I find a pump with the return fitting?.
I've checked a lot of corvette parts sites with no success. Thanks!

1969 350/350 came with only 2 lines on the pump. The return line connected to the fuel filter which had 2 outlets a 3/8" and a 1/4". The 1/4" had a short hose connected to a pipe which ran down to the frame rail where the return line is located. If you have a 3 port pump it is wrong. Google GF432 fuel filter.

Do you think your Corvette was originally set up like this?:

That's correct for a 69 350/350 but the poster doesn't appear to be aware of that.

I think it was. This is my third 69 vette and the other two were exactly like the drawing. Ive had this one for ten years and it came without the filter shown. .I can not find the pictured fuel pump on line.

Then you don't want a 69 pump. You want a 70
