You mean it's actually growing there? No rain since last August here in Mathis.
Farmers and Ranchers living off the insurance they take out in advance in case
of no rain.

> Replaced the air compressor (500cfm)with a 700cfm. Repaced the air governor
with a new one.
> Replaced the air protection valves. Interesting. Got 2 new ones from Ryder
Truck. One swapout, no problem. Replaced the second one and the problems
started. Seems the old one has a set screw on the bottom that adjusts the
pressure on the tag air bag. The new one didn't. Put the new one in and watched
the air bag gauge almost go to 150 lbs!
> Couldn't figure out the problem for about an hour. Looked at the old one and
saw the difference. Took the old one apart and saw the diaphram was in excellent
shape, so put it back in the system. Pressure dropped to 35psi, like it should
be.

PT40's have a third one in the front.

over everything and can't find it. Hummm...

the 85 db from 95-98db. So better.

not to much.

fuel lines going to pump. Use a pry bar to move pump out or in as needed. In my
case, had to move it in about an inch.

into the oil if you don't.
