Could someone tell me if the same vacuum line that is used for the boost gauge can be tapped into for the fmu? Or should it have it's own vacuum point? Thanks

 

ideally you want he FMU on it own port, but i never had a problem when i tee'd into the FPR vacuum supply.

The FMU can source vacuum/boost from the same line running to your gauge. The FMU doesn't need a large feed to it- infact, most FMUs have a restrictor in the sense line. Just make sure the source is after the TB so it reads actual manifold pressure, be it positive (boost) or negative (vacuum).

 

Thanks for the info, I will be hooking it up tomorrow.
