Looking for dual carb fuel setups. Would love to see type/routing of fuel lines, how you ran them, how you set up your linkage, where you installed your fuel pump, filter and regulator (if any).

Thanks!

couple of things...

were not talking fuel injection here.
especially in the -6 with the PMO rails, all the fuel has to do is flow (downhill) into a bowl. The floats shut that off when they are full. No need to distribute it evenly.... just need to keep some in the bowl, and you'll know it if you can't keep that done. Even with 3lbs of fuel pressure there is still plenty of fuel to return to the tank after filling the bowls. (I've got Wideband sheets to show I'm not running my bowls dry.... maybe if it was a 3.6 I would (doubt it), but its pretty effective for me.

the -4 carb doesn't really have a convienient way to go from one to the next and that a part of the reason my plumbing was different when I ran a -4

by having the fuel flow past one carb, it assures circulation and cooler fuel.
having fuel sit above the motor where heat is radiating into it is not a good thing.
in fact as you'll notice in my picture on page 1, we bothered to heat rap our stainless lines every inch of their travel after exiting the firewall. (hot zone)

Modern fuels Suck even as low as at 100 degree's F
fuel injection pressures can mask this.... (and is the reason modern cars don't vapor lock.

but carbs and especially carbs at 5000 ft don't mask it as well. (altitude reduces cooling or air density you know) Most of the SCCA guys in colorado run cool cans on their fuel in the hot engine bays. Check out the mazda guys sometime if you don't believe me.

but heck..
you don't like it thats fine with me.
thats the beauty of free will.
