Thanks,

You can use -SOME- compressed air to see it there is a break in the line somewhere. (less than 5-10 lbs)
100+ lbs is NOT recommended.

Make sure your rubber hose isn't kinked or stopped up with sand or mud.

Take a short piece of hose and hook it the the back of the speedometer. lightly blow into the hose.

You should be able to max the speedometer out and it should return to zero smoothly.

If that works, then look at the hose or pickup.

Post by: BROKEDIK on April 03, 2014, 08:49:50 PM: I bought the auto meter one from summit racing. It works great and even has a built in hour meter. It was kind of spendy but it looks great, matches my tach, and always acquires signal in @10 seconds.
I had the lowrance one in a race truck I used to have and it worked ok but was plane looking and had a huge transponder/receiver. The auto meter one is only like 1 1/2" square and 3/8" tall. You can hide it just about anywhere.
