vacuum gauge install

[lonewolf]

I finaly got my car back after some lengthy engine repairs (caused by a pretend mechanic) and the garage that he worked for took the car back for the repairs and fully rebuilt the engine for me, inc lots of new internals parts

While it was away I aquired a few new bits n bobs which I want to be fitting myself. On of these is a HKS Vacuum Gauge. Before you start flaming it... it was FREE, salvaged from my brother-in-laws crashed DC5 (not his fault, some crazy stupid b***h in a 4x4 thought she owned the road and drove sideways into the rear 1/4 just like the cops do to criminals on the run. spun round and round and round before meeting a concrete ramp and took off. He is fine apart from whiplash, but the car was totaled )

All I need to know is which hose is best to connect it to (and don't say a vacuum hose ) I haven't done anything like this before so I really appreciate any help or advice you can give.

Many thanks

Tim

you need a clean vac source close to the manifold. If you have a spare port on the manifold do that, if not T a line close to the manifold

i DONT suggest T'ing off of the fuel pressure regulator vac line. IT MIGHT work, but i dont know if its kosher to T that line. Has anyone that reads this ever done a swap and maybe T'd off of that FPR line? for cruise control? or maybe a vac guage?

you could always T off a manifold vac line. seems like that's where a more acurate (and important) reading would be.

FPR is not the best spot, but it is beeter than coming off the MAP sensor. well that is if you can T off your map sensor.....is that only 4th gens that it isnt mounted to the TB?

Thanks for the help.

I T'd off the one coming out the back of the im on the bottom right (when looking from front). That was going to the evap purge thingy.

Thanks!
