150 gph. He is going to a gear driven fuel system. His truck is supposedly running some serious fuel and the people doing the truck say it wont be enough. There is nothing wrong with it. If i had the money i was going to buy it. I have a 95 gph system with about 1000 miles on it and am now running lots more fuel and have to upgrade. Unexpected change of plans on my truck. Ill sell mine for $375 shipped
