Setting up fuel lines questions with external AFPR.

[turboclam]

Coming from the tank I'll have a -8.

Was thinking to dual feed from there (-6) to the front of the Champion rails.

The regulator is an Aeromotive with (2) -6 bypass? With a -8 return.

Can I screw the AFPR to the back of the passenger rail and just tie in the other rail to it?

I've seen them mounted several different ways but a bit confused.

I'll primarily be running pump gas and Alky and in the 6-700 hp range. Stage II, TA heads 71hpq bb.

Oh, will also be using a TR6 in stock location.

Thanks

My opinion is to build and assemble any mods with the most simple and easy way as possible, and this applies very much to the fuel system and lines.

Mounting the cumbersome aftermarket fuel regulator on the rails is something I avoid at all costs. I want to minimize the number of fittings especially when plumbing fuel lines on and around the engine, and want the regulator in a remote, off the engine, but accessible location.

I have used dual feed supply lines to the rails many times, but when I split the line I still use -8 from the Y to both rails.

A -6 return line is more than adequate for your application.

Most engine fires I know of personally, but never mine, usually are caused by fuel leaks which is why I strive to keep things simple.

My -8 supply line at the rear of the intake and the return also, no Y block is even used!

Supply fuel is transferred to the other side by a line at the front of the intake, and the Aeromotive regulator is mounted on the frame.

Does not get any "simpler" than this!
