W-31 Fuel Pump/Fuel Line Pics Needed

Anyone have a picture or two they could post of a factory W-31 fuel pump mounted to the car as well as the metal fuel line from the pump to the carb?

Need a pic of the W-31 fuel pump as well if anyone has it. Also, is the AC Delco part number for the '70 W-31 '40713' or '40711'?

Thx

I'm not sure I'd say that. Both the automatic and manual '70 W-31 used fuel pump 6440772. The only other applications to use that pump were, of all things, the 2-bbl 350 in A- and B-cars with automatic trans and A/C. According to the Engine Assembly Manual, the 4-bbl A/C cars used the '713 pump, just like all the other 350s.

I don't have engine assembly manuals for '68 or '69, so I don't know. You'd have to look at Olds parts catalog listings, which are not always 100% the same as what was installed in the factory.
