FPR gauge on a 12:1 FMU??

[starfish]

Will a gauge off a FPR work on a 12:1 FMU?Is it possible to tee the gauge in somewere on the fmu?If so where is the best place to put it?

As long as you have the appropriate adapters to put a gauge in, it will.... Most under hood gauges that I've seen are a 1/8" NPT. So, you'll need some sort of a tee with a 1/8" NPT female adapter in it...
It depends a lot on how you hooked your FMU up and what kind of fuel line you are running.

well I got the fmu back by the tank ,using fuel inj.hose,but which fitting on the fmu do I hook the tee up to?In or out. I'm also wonderin if I have to hook up the vac line on the fmu to the line on the stock fpr or can I use a seperate line commin from my manifold?

There's little to no point in installing a fuel pressure gauge with your current fuel system; there's nothing to adjust on an FMU. You'd be better off getting a gauge for periodically testing fuel pressure and using the test port on the fuel rail.

I answered your second question in your other thread -- don't cross post.

i figured that if I have the gauge right were I can see it,if the car ever started runnin funny at least I can look back and check my fuel pressure. I hooked it up to the line goin into the side of the fmu.Is this right place or should I hook up to bottom fitting?

Having a fuel pressure gauge will alert you to some catastrophic failure, but most likely, you'll know already because the car will shut off. They're just not common gauges to install. For safety purposes, you cannot mount a mechanical fuel pressure gauge inside the passenger compartment. So, having a gauge mounted outside of the car doesn't do you a whole lot of good unless you mount it on the hood facing the driver. Otherwise, you'll have to buy an electronic gauge, which is obviously more expensive.

well I teed in my fuel pressure gauge to my FMU regardless of what people wre saying and it was a good idea that I did.I only had 20psi.My FMU isa brand new Blox 12:1 fmu.I took it apart and noticed that the o-ring was out of place and pinched between the two halves.Plus the o-ring was too big .Would not fit into the groove properly.Once I fixed the o-ring problem everything was back to nomal so I took the gauge off and mounted the FMU under the center of the car(plenty of room to tuck in).Definately a safty hassard were it was (in the back seat).Now I even have room for extra passengers!
