Pressure gauge

where can I buy a temp/pressure gauge for my EFM that reads on a smaller scale, like 0-40psi and say 0-240 degrees so it's easier to read?

Your local plumbing supply house should have an assortment of different sizes with a variety of pipe sizes. Some are rear mount some are bottom mount. The gauge you seek with pressure and temperature is called a "tridicator".

something like this?

Found a handfull on Ebay too...but not supposed to post links.

If it's your eyes that is the problem, go with the largest diameter gauge that will fit as everything gets bigger as the gauge face size increases. Small gauges have very small print and scales. I use a 4" faced tridicator and it is much easier to see, I can read mine from the foot of the stairs about 20' away.
