I'm an avid Ford guy, but notice one thing I don't like on the F series trucks; pre 1998.
I noticed Ford just has a "switch" for a sensor, which swings the panel meter over the the "normal" area; rather a cheapo way and useless for watching it. I wonder if anyone has converted the sender to the modulator type (analog), like what GM and Dodge (I think) does. I have not check out what the rating of the meter in the instrument cluster is, yet. (how much current it takes to run the meter).
Otherwise I'm thinking of installing a "T" in the line with either an idiot light and/or buzzer, so if and when it happens (lost of pressure) I'll know right away, instead of the next time I happen to look at the gauge.
