It's also fairly easy to rig a VDO oil pressure sender unit to the
fuel line and use your VDO aftermarket oil pressure gauge you
installed(everybody should have one!) as a twofer. By rigging a
toggle switch between the OP and FP wires running to the gauge, you
can get both OP and FP from one gauge. Let's face it, 99% of the
time you're needing the OP info, but if the motor starts crapping
out, You simply flip the switch to the FP sending wire and see if
you're running between 29 and 36psi. The lower the manifold
vacuum(ie foot to the floor) the higher the reading should
be. Higher the manifold vacuum(coasting down a hill with foot off
the pedal), the lower the reading will be. Helps to let you know
when you're running out of gas, but that's not an ideal situation for
most folks to be in.
Good luck with it all.
