NOS 1971 Z/28 fuel pump

[Camaroresto]

I have no idea what the part number is. Car has smog and the return line. Thanks!

That's Chevrolet #6470423...aka AC #40726.
These are fairly common.I just sold two NOS for $50ea.
It's the same pump shared on the line by a multitude of Chevrolet & GMC 2bbl.& 4bbl. Small block Cars & Trucks beginning in 1970 as well as the years after it.It was soon superseded by Chevrolet #6470779 sometime during 1974-5,but still went by #40726 to AC.
AC soon superseded their number to reflect AC #40987 sometime before 1980.

Dang it! I am always late! I want it to be correct. If you come across any more let me know. Thanks!

71 Z-28's did not have a return line, it should have a single 3/8" fuel line. Also, all 71 Z-28's came with smog. If my memeory is correct, the original pump is part #67K40726. Good luck with your search.

I guess I was thinking about the lines at the tank/charcoal cannister. It only has the one line i think

1) How difficult to judge or read the 40726 when installed in the car

2) I have two 40726 that I need cosmetic rebuild .............Where/Who/What ???

3) I have an NOS 40727 in AC Box but dont know when mfg

Where can I see chart to learn mfg date codes

4) What was correct for my 70 L-78 (01C Camaro) ???

Should be a date stamp on one of the box flaps, either top or bottom. You may have to unfold the box a little.

I spoke to Paul at Goat Hill Classics...........

He takes old original correct castings that have the A/C embossed on side and correct weep holes etc and restamps
them to create 40726 pumps and other numbers. He sells these to Heart Beat City, Paragon and many
other vendors.....Evidently most of the restoration industry is pleased with these (???)

I see this above &quot;recreation&quot; on EBAY for $170.00

I have TWO Original 40726 pumps.......One is stamped CI 40726 (which Goat Hill said is 69' and older)
and the other is stamped 197J 40726 (which looks like a Julian date plus the &quot;J&quot; ????

Both need Cosmetic Restoration. Goat Hill only does a full dissassembly and resto for $137.50

Can somebody comment on my two pump dates and their possible value as cores OR as restored Originals (after I send them to GOAT HILL)

[CamarosRus]

Anybody do a correct cosmetic exterior resto on A/C Fuel Pumps without dissassembly ??

[WILMASBOYL78]

I had 4 or 5 of the #726 pumps done by Goat Hill....they turned out great.

Tom, Are you saying you had Original 4726 restored by GOAT HILL
or youve bought the recreated restamped 4726 A/C Delco Pumps???

I would think IF the recreated/restamped 4726 (and other numbers)
are made from the same basic castings as ORIGINAL 4726's
they would &quot;look&quot; identical !!!!

[WILMASBOYL78]

I had original pumps that I gave to him at Carlisle [maybe 10 years ago]....he restored them and shipped them back to me.
