Fuel return flow ? 1979 2f (1 Viewer)

[kellervernon]

just got my 79 2f up an running after complete rebuild.
at idle the return line is returning fuel at a rate of appxmly
gallon per minute. is this a normal flow?
at present I do not have the tank installed (gozzard tub build working on fuel cell placement)
so fuel is directly from plastic jerry can and fuel return plumped to a separate container.
set up to I can simply adjust timing and carburetor fuel mixture etc. and run the engine for an hour.
I was impressed at the fuel flow . I would never have know how much fuel is returned
if I hadnt had this makeshift setup.

thoughts on fuel flow? thanks

Is the fuel level in the float bowl correct? If so, I wouldn’t worry about it. Ive never had a reason to measure the return flow rate, but yours doesn’t sound absurd.

Under full throttle there will be no return, all used

Flat level seems correct per FSM. should there be a continuous flow? Even as the throttle is higher there is still

Under full throttle there will be no return, all used

thats what i was wondering. I should see a slower flow in return as throttle increases.
what if I do not?

just joking with you mate, but i guess it would slow a little, unless the increased rpm made it pump more. I have never checked one but if its running fine i would not be too concerned.

Guess that makes sense. Thanks all.
