I Posted a new thread, in case there are issues unique to the 235. I was very concerned, because the pressure gauge said I had about 30 lb. while running down the road, but it dropped to ZERO while idling.
I did an oil change and put in straight 30W. No difference. So I went to AA parts and bought an inexpensive mechanical gauge. It sais I have almost 30lb. at idle, and maybe 35-40 on the road. Whew! So, what could cause that difference? Before I replace the original gauge, which at least functions, what else can I do? Could the old tube be the problem? Blow it out? Hook up the new plastic tube temporarily to see if it matters? Any ideas? I don't want to buy a new gauge if I don't have to, but I do want accurate readings. Thanks.
