| propane, measuring pressure
while restoring the 72 overlander, i installed a new regulator, the kind that switches to the second tank when the primary is empty. now that i'm on the road, i've had problems with pilots on the stove and h2o heater and also with the dometic refer when operating on gas. there was no improvement after the usual cleaning routines. i began to suspect that the gas pressure was too low. i took the black pastic cover off the back of the regulator, found an adjuster and cranked it down two turns with an allen wrench. now the h2o heater stays lit. i haven't confirmed an improvement with the refer yet. it's been on shore power and i don't want to risk getting my beer warm.
the question: has anyone tried to improvise a manometer using clear plastic tubing in a "u" shape to raise a column of water and thus measure actual pressure? it's been a while since i read the dometic specifications but i seem to remember something in the range of 10 inches of water as the correct gas pressure (measured at the appliance).
