Cliff's Quadrajet Parts and Rebuild Kits

Did you use your original tank?

I used the original tank, but it was a pain getting everything to fit. A tank for 175 that's made for an in tank pump would be easier.

Dualquad, Tanks Inc. makes a tank for a 69 Chevelle for $175. It's ready for an electric pump.
You can use theirs or buy your own. I think this is your best bet. You'll spend more time and money welding up you existing tank.

I wonder if they continued to produce marine carburetors after 1990?

The last original Rochester Quadrajet carburetors were produced around 1990.
This end of production applied to both automotive and marine applications, as electronic fuel injection systems became the standard.

If you bought a new replacement Delco/Rochester Quadrajet for 1990-88 Buick, Cadillac, Chevrolet Oldsmobile or Pontiac you would have a 24-5092.
24-5092 is stamped 17111994 and it replaced 17088115.

Info from 1997 ACDelco Carburetion Catalog.

Cadman-iac,

Thanks for your reply! To explain what I'm trying to do, sometime around May of this year my son and I started a project to identify all Qjets produced since 1965. At present we have identified in the neighborhood of 1270 different Qjet numbers with over 1900 different applications including some from Australia. In order to do this I purchased several Delco Rochester "9" Parts and Service manuals(aka the Big Book). They covered the range from before the Qjet in 1965 to 1989. These are directly from the manufacturer and as close as one can come to direct confirmation of the numbers/applications as I can do.
So I was looking for that elusive 1990 last application index sheet(it may not even exist) to finish my database.
I appreciate your insights into the usage of the 17088152 carb as It helps clarify my understanding of  it's application and it helped clarify that it was the highest numbered automotive Qjet used(not the last number used as I originally believed), that appears to be 17088115 or the highest numbered Qjet used 17089112 Mercruiser Marine.

Hope this helps.

P.S. I'm partial to Cadillac carbs. I'm running a modified 17057230 on my 1972 Super Cheyenne.
