What part number(s) does it show for the 1967 L-78 fuel pump including anything shown in the revision block?

It is in the cold garage, but I will look and post later today.

My underlying interest is in trying to figure out how the 40170 "morphed" into the 40358. If I can find the original application of the 40358 I MIGHT be able to figure it out.

1967 Chevelle UPC L78 Sheet A5 Item #6 6440470 Pump Asm-fuel. Nothing at all in the revision block. I can send you a scan to your email address when I next go to work on Wednesday.

Re: 1966 Chevelle AIM

I had and I have, and the work has just been completed on this one after owning it for over 30 years.

[ATTACH=CONFIG]43695[/ATTACH][ATTACH=CONFIG]43697[/ATTACH][ATTACH=CONFIG]43696[/ATTACH]

In our younger days my brother and I owned literally dozens of Chevelles (Usually, but not always, serially. This made our parents less than happy for a variety of reasons.) Back when they were just used cars. That is a long story for another place and time, but I grew to love 1967 Chevelles. Over thirty years ago I dragged this one out of the south side of Chicago from the garage of the original owner. Of course it didn't look like this back then. I expect this will be my last one.

Terry, that is a beautiful Chevelle. I like that color combination. My dad had a '64 Impala 2 door, Daytona blue with bright blue interior (and port-o-walls). It was the best looking car he ever bought new. Way back when a friend's parents bought him a '67 Chevelle SS 396/375, 4 speed, 4.10, Bolero red/black for HS graduation. The incentive was if he would get serious, improve his grades and go to college they would buy him the car. It was 'quick"! His room mate had an L-88 Corvette. I got a radio with built in alarm for graduation and I still have it. I would rather had a Chevelle 396 or L-88.

Re: 1966 Chevelle AIM

Joe,

The 6440358 fuel pump is listed in my 1966 Chev. AIM (UPC L72, sheet A4).

My 1966 Chev. Parts Catalog (Oct. 1965) lists GM # 6416459 as the fuel pump for the 1966 Pass w/SHP 427.

GM # 6416459 = AC 40358 = 6440358

GM # 6415961 = AC 40193 = 6440193 in same AIM (UPC L35,L36, sheet A8)

GM # 6415748 = AC 40170

Having either of those big blocks would have been better than the alarm, on the other hand the alarm probably proved more useful in collage.

That is the original exterior color (in BC/CC) but the interior was a different color to start. It also had a vinyl top to start, along with a 327 Powerglide. I still have the original trans and engine -- both rebuilt.

Re: 1966 Chevelle AIM

The 1965 Chevelle AIM lists fuel pump # 6440248 for the 396 engine (L37).
The 1966 Chevelle AIM lists fuel pump # 6440193 for the 396 engine (L35,L34,L78)
In the revision record 6440248 was changed to 6440193 on 8-7-65 (or maybe 8-2-65).

The 1966 Chevrolet AIM lists fuel pump 6440193 for the 396 engine (L35,L36).
The 1966 Chevrolet AIM lists fuel pump 6440358 for the 427 engine (L72).

The rebuilt 40358 fuel on Ebay has a 2-digit date code ("7A", "IA", or something else) stamped just before the "40358" but I can not make out the digits because of the media blasting.

Re: 1966 Chevelle AIM

Thanks to all. I feel pretty confident we now know the GM part number associated with the AC 40358 type number. From the information you all have provided it looks like the 40358 pump was PRODUCTION for 1966 Chevrolet with L-72 and, according to some references, SERVICE for 1966 Chevelle with L-34 and L-78. This is also generally consistent with the unconfirmed information I had found earlier.

Just how the 40358 came to be supplied in AC Delco boxes labeled 40170 and GM #6415748 is still unclear. However, a "clue" might be found in the 1989 edition of the AC Delco fuel pump catalog which I posted in the other thread (titled "fuel pump rebuilding kits"). In this catalog, it showed the above-referenced applications being SERVICED by AC #40170. I expect that by that time the real "40170" had "morphed" into actually being the 40358. It does seem unlikely to me that a real 40170 (i.e. a screw-type pump) would have been supplied as SERVICE for an application originally using a Unitec style pump. But, who knows? Perhaps, the cataloging of the 40170 for the aforementioned applications was an error and it was "corrected" by making the 40170 "become" a 40358.

By the way, I wonder what the difference was between a 40358 and a 40193?

Apparently the inlets are in different locations.

Yup, that's what it looks like. The fitting orientation on the 40358 I have is also more-or-less the same as that shown in the AIM for the 40358.
