i,m in the final stages of the engine rebuild and currently hooking up the fuel supply to the carbs. the way i had it set up on the 40 idf was from pressure regulator to first carb then from carb # 1 to carb # 2. some folks say that i should come off the regulator to a "tee" and supply both carbs equally...the new carbs are the 44 idf... does it make a difference one way or the other ?
another thing, i want to do something with the extra fuel line, the return line. some say to keep it intact to be used as a back up line, some say to cap it off at the tank. i want to keep the clutter out of the engine bay so i need to hide it or get rid of it altogether...
Simple answer...
Tee off to the carbs after the pressure regulator.

so you are saying that carb #1 could starve carb # 2?
I would use the Mallory fuel pressure regulator w/return to the tank. Fresh cold fuel to the carbs.
Other than that, pressure reg..."T"......lines to each carb.
cap off the smaller fuel line at the tank. Snip it off or pull it out. Chances are in a year it will have so much crap in it you DON'T want to run gas in it anyway. or be so dry rotten it won't hold gas.
Yes,
also install a pressure gauge after the regulater, before the tee.

On mine - Holley regulator with 2 outlets, one to each carb, pressure gauge on fitting next to regulator.
Looks cool with braided stainless lines too, wooooo
the fuel pressure gauge is in hand and will be installed after the regulator....what kind of pressure will i be looking at?...
what i did was use a rotery pump that i didnt have to put a regulator on.with webers volume is key if you ever drive it hard.IMHO also less items to put in line it looks cleaner.i run 4.5 psi to my IDFs

i ditched the return line.
i went P. Regulator ----- Tee ------one line to each carb
no more than 3.5psi to the carbs

Mallory reg feeds in the bottom and out the sides to each carb and then the return out the front. |
