Let's find some middle ground... if possible. I'm sure 95% of the questions that pop up here have been covered before, but this forum would be pretty boring if it were just a search site for previously discussed topics. Hopefully we all remember our first few posts and the time it takes to become familiar with the 'protocol' of this BBS. Besides, periodic review of covered topics gives us something to do and helps fellow enthusiasts try things themselves.
This being said, Slantnose you should try to find out some of these basic things for yourself before firing a question back. Phil told you where the oil pressure sending unit is and what it looks like. Finding the part # is as easy as clicking over to the catalogue section of Pelican. If you can't find it, sure, ask someone. Maybe a more specific question about testing the sender unit wouldn't have rankled, ie 'does anyone know the resistance value for a working oil pressure sender' if a search doesn't yield the answer (and sorry, I don't know that either). No one wants to discourage anyone on this site, i'm sure. But it would look better if it appeared that you were attempting to make some progress on your own before asking your followup questions.
OK, I'm better now.
