L69 Tri-carb Photos & Info

[bocoogto]

I rebuild a lot of Pontiac Tripowers, but now someone has asked me to rebuild a '66 Olds Tri-carb setup. Can anyone on this board post some photos of setups with original fuel lines, linkage, etc.? Do they actually use copper lines for the front and rear carbs?

I found this, it belongs to a member of the ROP board, and yes its showing copper looking lines in this restoration.

Thank you, Don. It's the third photo I've seen with copper 5/16" lines to the end carbs and aluminum to the center from the fuel filter bowl.

Does anyone know if the GF48 glass fuel filter that has no drilled and tapped hole in the center of the housing is the same as the one that does? It appears that the Chevrolet ones don't have the 1/4" tapped hole. Is there enough stock to drill and tap a hole there on one without? The ones with the holes are a little pricey.

The fuel bowl is not a gf48 st all. The original was a gf 422, impossible to find, but a guy who sells the carb tags on Ebay sell a repo for $300.00 if I remember correctly, I have one, its very nice. An orginal if you find one will cost you $800.00 to $1200.00. Also the carbs fuel lines are available from him.

I got the fuel lines and linkage from a Pontiac supplier I know in Ohio. They are very well done. I have some original Olds linkage and fuel lines that someone had put on a '66 Pontiac Tripower I bought on eBay. Repros compare very favorably. This is the setup I'm building for someone with a '66 442.

Too bad about the fuel filter. The GF 48 looks exactly like the Olds unit, but there is no tapped hole for mounting on the topside. There must be a better way than $300.

If the repro L69 manifold happens, there will be a lot of Tri-carb 442's around. He has tried several times on eBay, but no one has yet met his reserve of over $400. Maybe he will decide not to go ahead with the project.

I see the recast L 69 manifold on Ebay all the time, if I could figure out how to post a picture or two I would of some substitutes that are close for the fuel bowl. A 62 starfire and early like 63 Caddy both without AC are what a lot of people use but they are not 3/8 inlet and outlet like the olds one is, they are 5/16 and then you have to get brass adapters to make them work. This is the guy that sells the fuel bowl, plus the clamps, bracket and other items.

I found it one EBAY!

There is one for a 50's Chevrolet/Corvette application that does have 3/8" inlet and outlet. It does not have a tapped hole on top, though.

The threaded fuel bowl has a neck on it that is raised about an inch over the top of the fuel bowl. That is where the threads are and why the GF 48 won't work, it dosen't have that extra material.

The line from the fuel filter to the fuel block is steel, coated just like brake line. The curves on the copper lines in the photo are incorrect, but Mike Siedlik is now reproducing lines that are correct. Same for the bends in the line from the fuel pump to the filter--it was steel and straight with both the ends bent about 45 deg. Resto pieces Ii have seen were wrong until Siedlik began doing them.
