Everybody with turbo projects stop in and say hi

I used 5/8 line on mine for both the supply and return, seems like I remember someone on another board with a similar problem bacause of a too small return line.

Not sure if this would help, but I was talking to Aeromotive last week about their fuel pump Speed Controller. They explained that you do not want a large volume of fuel circulating through the system since the fuel carries heat from the engine back to the tank. Not sure how true this is, but it liked the idea of controlling the fuel volume based on RPM's. This should also help fix any problems due to too small of a return line.

Let me know if anyone is using one of these since I'm planning on ordering one.

My car is a 69 Camaro Convertible, ZZ502, Whipple EFI Supercharger, and Aeromotive's pump/filters.

Those controllers are cool.

I'd suspect the return line issue except that the problem stops when the boost-reference is bypassed. I'm convinced the regulator is increasing pressure based on faulty info. There is either something going on in the hat or that "T" with the baseplate is somehow screwing it all up. I'm going to stop Ninja-ing this thread and move this to another thread....
