I was wondering if anyone has used a check valveon their back pressure line to help aid added distance of their fuel tanks location?

I recently mounted my fuel tank on my Cap 580 on the CG. It's only about 2.5 inches from the standard location in the fuse.

If anyone has used a checkvalve I look forward to hearing your experience.

When you use a check valve you need to also use a regulator, the check valve traps the peaks of the exhaust pulses and makes considerable pressure especially at full throttle, then when you go to part throttle all that pressure is trapped making the mid range very rich.
