Pump choice??
I use the Eliminator series Aeromotive pump, regulator and filter. The guys at Aeromotive tell me it'll work on the street.
I have a NEW Weldon, in the box, in stock. They are expensive!
I don't recall the exact net on it, but as I remember, it was in the $500 range..
As for the return line. It's about a 3/8" OD and has serious restrictions at the fittings for the filter and at the ft end near the engine. These restrictions are where the o'ring seals fit..
I am using the stock tank and have the -6 return line AN fitting welded to the upper corner of the dr side of the tank. It has a steel tube extending down into the fuel along the side of the tank. This cuts down on foaming the fuel caused by blowing it out into the air in the tank.
As for the pickup, I have a -12 bulkhead fitting in the bottom of the tank that picks up fuel in the plastic baffle area that's in all GN tanks..
Seems to work ok. I have a data logger on the car that monitors fuel press. and it shows a steady PSI during a run..
On the engine, I have large bore rails that are individually fed w/ -8 from a manifold. The rear of the rails are plumbed to the reg and then back to the tank.
The elec. feed is a relay system wired w/ #10 wire and I have added several grounds also. The relay is triggered by the stock pump wire, thru the FAST system
HTH,
