fuel log vs line to each bowl

given the choice of a fuel log or a fuel line from the regulator to each bowl, is there any difference or advantage over one setup or the other?

I like to run a fuel line to each bowl but just my opinion

Re: fuel log vs line to each bowl

Fuel line to each bowl for sure!

If you ever tune you can take the bowls off individually with separate lines -- you don't even have to disconnect the fuel line from the bowl.

Fuel logs do look cool though.

Re: fuel log vs line to each bowl

Also is he talking about a fuel log dual feed unit OR a "REGULATOR MANIFOLD"

Some people call a Regulator Manifold a fuel log

Re: fuel log vs line to each bowl

That appears to be a "dual feed line" and not a log but the pic is so small

This is what I consider a fuel log

Re: fuel log vs line to each bowl

Main reason to run a log (not really what you have pictured), is if you run a return line and bypass regulator. This way the regulator is completely out of the fuels path to the carb. The regulator is on the outlet side of the log.

As long it's not the "double flying trapezes" strung out & over from the fenderwell, it's worth a million.

Is that so important? And if so, then why?What is the benefit? And how can the regulator actually keep the fuel pressure that's entering the bowls under 8 PSI if the regulator is not in path leading to the bowls?

^^^^ it's a bypass regulator on the end of a log.

Bypass regulators control pressure by varying the amount of fuel going back to the tank. On a regular bypass regulator the fuel is technically going to the carbs prior to going to (actually through) the regulator.

Here on my setup it's the same thing as a fuel log. Fuel goes in the side under the "A" symbol, goes to each bowl unrestricted, once 8 psi is reached going to each bowl the pressure pushes up on the diaphram and there is a check ball on the bottom that unseats to allow fuel to return to the tank.



i prefer the above instead of a log so you can make jet changes easier. I can leave the lines going to the bowl attached.
