Finally this weekend started looking at my sending unit - doing the testing suggested by Centroid. The next step is to remove it from the tank. I have taken out the 5 screws, but it won't even budge when I try to twist or rock it. Is there any secret to getting it out without messing something up? Like gently twist with some channel locks?
NEVER MIND!I got it. Just slight pressure with a pipe wrench is all it took to break it loose.
While I am at it, thought I'd post a couple of pix...
