To answer your Question about a bigger Pump..this all depends on the Size/hp Motor you have ?
1- 650 hp down you just can't beat Old Faithful ( Holley Blue )..
2- you can buy the O-ring kits On-Line to rebuild the BG for a low price of $9.99. My old Vette had a BG400 and it leaked after sitting a few years.. i rebuilt it with this fit and it ran perfect ( no-leaks afterward)
3- I am MAGNAFUEL all the way...DANG best Fuel pump I EVER had..i run the Pro-star 500..(good for 2000 hp).....Most engies can handle the smaller pump.
