I just used a corvette regulator/filter so it returns at the stock filter location, but is returnless at the fuel rail. A return system is better, this was just simpler.

Have pics or diagram? I'm going to be installing mint withing the next couple of days

Bump.

Did you use the 1/2 or 1" okw blower spacer ?

the 1/2" ones are what are used mostly, the 1" ones were version 1, and are only sold now as special order, theres really not any benefit. I run the 1" phenolic ones on my yukon as a testing platform, going on over a year and 40k miles.

If I plan on spinning the blower to 7500 rpm, in your opinion, would I benefit from the 1" spacer?

i hope you mean engine speed not blower speed. but above about 6800 rpm all youre gonna do is throw belts all the time, regardless of what adapters you run. The spin down on the LSA blower is brutal, it carries a lot of intertia. as soon as you let off its gonna throw the belt. blower speed should be in a 22k range max, most guys run in the 19-20k range. id lower the engine rpm and raise the blower rpm. either of the adapters will work fine, the 1" ones were just the old version.

Yes, the motor rpm. Thanks for the heads up.
