Ken,

When I first got my coach, I rebuilt my Dana pump using the same kit you
used, and it still did a poor job of filling that big Power Level tank. The
roads here are neither flat nor straight, and my bags draw air on long
sweeping turns. My pump runs a lot more than yours, and the Viair pump
works a lot more quickly.

Doesn't the EL-I in your '76 use a small tank?

You are correct the tank is something just over a quart. About the only time that I hear the compressor kick on is if I switch from a relatively flat interstate to a 2 lane country road. Also if I pickup a good crosswind it will auto level and sometimes kick on for that. Due to the delay in the level sensing switches it seldom corrects much for normal road variations. The corrections only occur if the out of normal conditions stay constant for a period of time. I do not know what that time value is. To be honest I seldom think about it since it is all automatic like GM designed it.
