Not to hijack the thread, but I have a 4-port dual carb. regulator...How would I plumb in a return line with this regulator? I have ran it as is with 2 ports plugged.I want to switch to e85 and would like to have a return line. The internals have already been changed to run e85, but if i need a different regulator, so be it.
Check with the mfg. If the black fitting is the inlet then it looks like you just have four outlets and no return line but maybe there is something else going on that I don't see.
