I think your all familiar with my cat but for those who aren't I have a 1987 BR100 with a Chevy LS V8. It has taken a couple of seasons to find and fix the small issues we have had with the modifications. Last season I was having no throttle on steep hills. I would have it floored and it wasn't making any power. Someone at the Vail Jamboree suggested that the in line pump was having trouble pulling gas. And that I should put in a second pump so the in line pump didn't have to pull fuel. It helped and I had barley enough power on steep hills. So we tried to do a full day of cat skiing and about half way thru the day it died on a very steep hill. Once I got it started it would only go about a mile and it would die and need about 15min to restart. The gas tank was under negative pressure. So I did some research and found that the issues with throttle, power, and tank vacuum were probably being caused by the stock gas tank. With the EFI v8 you need a vent so the tank won't make a vacuum. The pump works the best if in the tank. And the in tank pump wants a foam bladder to keep the fuel around the pump from sloshing. So a company called Areomotive makes a system that solves all of these issues without replacing the tank. Basically you have to cut a hole in the tank "replace shorts" and install a foam bladder and fuel pump. From there it's just fuel line and wires.
