boost gauge

How do I put a boost gauge in my MCI7 bus with an 8V92.

Buy the gauge you want mount it in the dash run your tubing to the rear ,and the turn down pipe on top of the blower  the turbo connects too has 2 or 3 taps for the supply line to connect into, don't waste your time buying a electric gauge buy you a 20lb mechanical gauge you will never see over 15lbs to 18 lbs anyway, the gauge will dictate the size of the plastic tubing 1/8 or 1/4 inch it is a  easy install

That is what I did on my MC5C 6V92. The plastic air line melted in the engine compartment, so I used a hydraulic line for the first couple of feet, then plastic air line to the gauge on the dash. Worked good.

I bought a 50' roll of 1/4" copper tubing and found a 1/4" threaded hole in the top of my blower and mounted the tubing there.  That was 20' years ago, and you may have to take out a small loan to buy a 50' roll of copper tubing now.

I also used some 1/4" OD copper refrigerant tubing from Home Despot (but only a 10 foot roll) from the threaded port on the driver-side of the air horn between the turbo and blower where my old Quickstart ether-injection nozzle had been, connected to some 1/4" plastic air line to a VDO 30 PSI boost gauge.   The highest I've ever seen on it was 26 PSI (with a brand-new air filter), but normally about 23 or 24 PSI is my max.   When climbing long grades in hot weather I drive only according to the boost gauge and coolant temp gauge:  if I keep boost below 18 PSI with a 3/4 pedal at 2000 RPM in 3rd gear I can hold indicated temps below 200-ish, but if the boost rises even slightly the coolant temp immediately also rises (boost pressure = fuel burn).
