My fuel cell only has -10 outlets. Magnafuel shows a -12 line between the fuel cell and pump. Would it starve the pump if I only ran a -10 line between the cell and pump. Car is a 67 Firebird with a 496- makes about 800hp. Might put a 200-300 shot of N20 on top of it at some point, using a Y-fitting to feed the carb and the solenoids

I used -10 to the Magnafuel 500 pump as that's what was in the car already from a previously failed pump.. Has been fine @ 700ish

The suction hose to that pump needs to be -12. So does the vent. Anything less will starve that pump and lessen its life. Whats the bid deal. Cut off the -10 bung for the suction and weld on a -12. Then get a roll over -12 vent valve and drill a hole and put that in. Make dam sure the return has the right size hose and fittings and goes to the bottom of the tank too. That pump moves a shit load of fuel. It will aerate the fuel bad if you don't put the return to the bottom.

Nice, I didn't want you to hurt that monster.
I'm old, I still use antique Holley's & BG's on all my cars, didn't know it had one.

Just noticed this part. Don't use a Y fitting. Put your regulators on a fuel log to give them a little volume of pressurized fuel to take the hit better. Get a triple hole at least. Gives you room for the fittings on the regulators and you can drill and tap a plug in the middle for a gauge. That way you can see log pressure, carb pressure and nitrous pressure in one spot.

We still run a Holley Dominator carb too. Wouldn't have it any other way. The MF pro star 500 is a carb pump. We run a Aeromotive A3000 on ours, but basically the same setup. Several of my friends run the MF 500.
