CaptainP 2 Posted August 5, 2007 Hi, my oil pressure gauge has been all over the place for the past couple of weeks. Yesterday I tested the wire from the brown multi-plug to the sender unit and all seems fine. Searching has revealed that it's most likely to be the sender unit itself which is on the blink. It's described as a "mushroom" shaped unit in all the threads I've read today. Can someone take a look at my linked pic and tell me if this is the mushroom type sender as I've heard there maybe a later type of unit which is different? Also what size spanner do I attack it with from the underside? http://i190.photobucket.com/albums/z295/Ca...Ti/IMGP0495.jpg Thanks Steve Share this post Link to post Share on other sites
