[Shotimes] fuel pressure issue

[Ian Fisher]

Anything larger than a 155lph can wear out the seals
in the stock regulator and cause the motor to run lean
(?). A 190 pump runs a few more psi than the stock 39
psi. I forget what the 255 runs at. www.APEusa.com has
some flow charts. Josh's site probably explains it as
well if you look under "performance" and then click on
his adjustable FPR link.
