under dash oily; leaks oil in cab on trans hump - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So, my truck has had this problem now for quite a while... I actually put it to the back of my mind, and then thought- hey maybe someone knows what's going on and can help me figure this out. It drips very slowly onto the trans hump and when I put my hand behind the dash, I get an oily mess.

I am 99.9% sure (speculation- haven't poked under there yet) that it is an oil pressure line for the oil pressure guage. Is that correct?

I thought the oil pressure guage was a one wire sensor that went into the block... Now, my oil guage is definitely stock (or OEM looking anyways). My oil pressure guage works just fine.

So a) is the leak an oil pressure line, or b) what else might it be?
