Fuel pump/Line size question

I haven't posted here much at all, I am mostly on the S10v8.org site. I have a problem with my electric fuel pump and it's pressure. The pump is an Aeromotive and I bought it used and now finding out it puts out way too much pressure for my fuel lines. The lines are 3/8 from pump to regulator and 5/16 return back to the cell. Pressure coming off regulator is at 8 and cannot be adjusted down at all.

Aeromotive tech said I would need 1/2 lines to and from for that pump. Well the pump has a leaking seal so I need to replace it. I would like to keep the fuel lines I have, I am looking at some of the Carter pumps.

Does anyone have a suggestion for a pump that would work for me? Engine is a stock 350 Vortec engine with a Holley 600 single pumper. I would use a mechanical pump but the engine does not have the rod hole on it.

Sorry if it seems like I am a "One hit wonder' but I am in need of some advice.

Thanks
Mike

a carter pump will be fine.. or a holley
or warboro, some late 80's early ford trucks with dual tanks have pump on frame rail.. that work, but you'll need a regulator to bring it down to 5-6psi..
you have a return line so I'd get a pump that will do 15-18 psi and regulate it with a regulator but not a deadhead type. you want one that returns the extra fuel to the tank..
the pump you have is overkill.. and most likely a drag race only(read short term use)
part..

A carter P4070 is just right. no regulator or return line is needed either.

Thanks for the help, still haven't decided but the Carter seems like the best bet. I'm just a little cautious, seems like when I get one thing done lately something else goes wrong.
