CV:

I run the Holley 12-125 (I know I said 225 above...my mistake) on FFR 8317. It is a bit noisy, but not bad. It can be heard when the engine is not running, and detectable at idle. It can't be heard while underway. Also, I don't run a regulator as it is internally regulated at 7 psig, so a return is not necessary.
