i bought one brand new installed it exactly as the bg tech said with a -10 an lin into the bg filter into the pump a -8 line out a -8 line for a tank vent and using a bg step down box i had a total of 30 miles and a few 1/4 mile passes and it started poring fuel out the weep hole. almost started a big fire
sent it back to bg. they would no way shape or form stand behind thier product. they said the motor was bad. they did not know what caused it i talk to sevral people at bg they refused to do anything about it. cost me 120.00 to have it fixed and shiped back to me i then sold it the step down box at a swap meet
i then bought a magna flow 275 pump new from them. been running it three years with flawless resaults. after the price of the pump and the step down box it is cheaper to buy a magna flow pump.
right now got mallory 140 a gal in 35 seconds ,,no my nos side holley blue 45 seconds ,,thats why a need to knoe what the bg flows,,,,im runing 10,s on motor 408
if i rember right i did flow test my bg i thing it filled a can in 25 sec.
my magna flow does fine i run mid 9's on engine no problem i also have a holly blue to run n2o still have to hook it up and see what it will do.
