The ramps I used are the kind you see in auto stores, drove up on them, front tires.
I snaked the 1/4" tubing over the rear trans crossmember to the modulator pressure tap, otherwise the tubing will have to sharp of an angle and will probably kink.
Then used a tie wrap to attach it to the fuel lines under the car, pull the slack out so it does not drag the ground or get wound up in the drive line. Put gage in through the drivers window, and took it for a drive to check pressures and shifting.
I set the pressure first, before driving.
And I used air brake quality plastic tubing, don't think you want to use just any ol plastic tubing, might be a heck of a mess.
