[AT] off topic, Internet takeover by govt ?

[charlie hill]

Thanks Steve, you and I talked about this years ago and I never could
find a solution.  At one time GM was using a valve from the S-10 trucks
and relocating it with heater hose to a not so dusty location but those
didn't work for long either.  I had given up.

Have you actually installed one of these on a GM pickup or SUV?

Yep the vent solenoid.
Let's put a part that carries oily vapor under the vehicle, out in the
open and usually stuck in a spot where dust flies around. Then for good
measure make it a critical test item for the EVAP system.

Thing normally sets open so air can vent the tank, it only closes for
the EVAP test. Because of this they rust and stick, and the test fails.
CEL comes on.

There is a way to fix it so it works and doesn't screw up. Replace the
factory valve with a better valve. I've used a couple of different
valves.

one like this works well. You connect it in place of the original, then
modify the filter from the oem so it attaches to the inlet side. You
need to look at how the valve you use works, you want to operate the
valve opposite the way it would normally be operated. That is because
you are blocking a vacuum and if you connect the valve wrong the vacuum
could hold the valve closed.
