This setup is made to fit directly to your G54B Throttle body. On the backside there is an allen head bolt you can remove and this will fit in that space without modifications. This is a custom fit piece, as the factory threads are not a common size. Fluid filled gauges are meant for areas with higher vibration like mounting directly to your engine.
Highly Recommend PTFE Paste on all threaded tapered fittings to prevent leaks!

A must have for when you’re replacing the factory injectors and going with an adjustable FPR. Be sure to have some thread sealant on hand for the install.
