Guys,
Just thought I would warn against "wet-line" Oil pressure gauges. There was one installed in my car when I bought it. I had planned to remove it and put a transducer like with the factory 240 style gauges, but had not gotten around to it. Yesterday I was going down the freeway to look in the rear view to see a cloud of smoke coming from underneath the car that was unbelieveable. "Uncle Buck" and "James Bond Smokescreen" were thoughts that I had.
As I pulled over the oil pressure light came on and I looked down at the wet-line gauge and it was zero.
At first I was sure it was a fuel leak on those D-Jet fuel lines(this made me newvous), but this was not the case.
Luckily I had a fire extinguisher in the trunk and I slowly opened the hood with my face away from it engine and hosed her down.

The oil was all over the exhaust and was just starting to catch fire. Mainly it had been smoking like crazy. But, at the speed I was going and there was no traffic on the freeway, I had not looked behind me often enough to notice it.
My engine was soaked in oil and now 3 quarts low.
After calming down and checking it out, the "wet line" oil pressure line was cheap polyethylene or some other crap. It cracked from heat and old age. It was very brittle and I broke it into little pieces like a saltine cracker.

Anyway, I had a few quarts in the trunk and removed the pressure sender and a brass "T" that had the connection to the gauge and limped on home, smoking like crazy to the carwash.

Just an experience I thought I would share.

Good luck and be safe. Learn from my stupid mistakes.
