Whats the best way to get fuel to dual carbs? I have been running a sigle carb so this will be new to me. Do i use a Y connector or something?

If your using Webers, they have connections on the carbs to feed a fuel line to another, or opposite carb. The tee connections are, so to speak, on each carb.

They do?

I have 2 44IDF sets that don't...
Perhaps IDAs do?
YMMV I guess.

I used flared fittings for brake lines, 3 barbed nipples screw into a "T" center, leak proof as hell, allows size adaptions, and about $10. The only thing better would be all Swagelok stuff... If I won the lottery.

(rather than rewriting that, I used brake line for all the gas line, including the fittings, and used brass components to make a "T"... baaahckthpt.)

(They could sell the brass stuff cheap enough---there would be a market IMHO)

(3/8"//10mm line from pump, 8mm line to carbs)

Dellortos have the 2 barb inlet on one carb, IDFs do not, You need a fuel line T, get a good one (Brass, not plastic) for about $10.

From what I've been told you are better off running a fuel line T or Y and running a seperate feed to each carb. In extreme application the carb the fuel line goes through first can rob the second carb of fuel... Not a good thing as one side of the engine could run lean.
Also, the float chamber of the carb the fuel goes to first will fill up first, once its full it will start to fill the other one.....

My IDF's have one inlet and two pipes on the left carb (when looking into the engine bay) and one on the right carb.
Its just a fuel banjo, then can be purchased as singles or twins.

Hope thats of some help...

I just put on dual Kadrons - here's my fuel path - fuel line hose clamped to outlet of stock fuel pump to a brass tee close to the left carb, short fuel line hose from the tee to the left carb, longer fuel line from the other end of the tee to the right carb.

The only tee I could find was a female/female/female pipe thread tee, into which I screwed in three pipe thread/barb fittings.
