Re: UPDATE!!! [3-21-11] x5carl3tmurd3rx's Turbo build
Hmm.. I ended up using a Megan Racing universal FPR with a gauge on it.. To put a gauge on, it would be best to use an AEM fuel rail, onto the end of which the gauge can be installed I guess you can use OEM fuel rail too, but you would need to make a precisely tapped hole for it to thread into. The closer the gauge is to the injectors, the more accurate your fuel pressure reading; this is where mine lacks since it is an inline FPR, not a fuel rail bolt on. The difference is miniscule though.
