oil pressure line

i have to remove my engine to do some clutch work that can not be done with it in the truck but the small line that runs from the block to the oil pressure guage broke i was looking to see what size line do i use to replace it and where would i get one

Any good auto store or speed shop. You can use the 1/8 nylon tube or the 1/8 copper tube line. You have to watch out for hot parts with the nylon tube it cost less and you have to be good at setting them up or the can pop off. The copper will cost more but look more like factory becareful not to kink the copper and the nylon the copper will be no good it kinks the nylon might work after leak after there. The nylon tube kits come with come with all most ever thing but the copper tube kits do not most times.
tell them you need tube end compression 1/8 fitting, to replace the broken one you have.
