Oil temp sender
I was under the hood doing a little electrical work when I saw something that gave me an idea. Folks who like analog gauges (me included) have had a difficult time finding a place to mount the sending unit for oil temps. Most have had good results with using a billet oil filter cap, or maybe adding a tee fitting to a bypass line somewhere. My problem with the oil filter cap is that the sender has to be unplugged every time the oil is changed...not a huge deal, but still something that has to be done. Has anyone thought about maybe installing a TEE fitting in the turbo oil feed line? The oil that goes into this line comes from the same vein in the oil cooler where the factory sensor is located. The "upgraded" line (no flex hose) has a fairly long, straight section that I think would accomodate a compression TEE fitting, with the branch connection being a FPT to install a sender. I measured the OD of the hard sections of my oil supply tube (I still have the flex hose one for now) and get about .39", bigger than 3/8", so I think its 10MM tubing. Does anyone have a damaged feed tube to check out? I have no idea what the wall thickness is or if a 3/8" compression fitting would work or not. 10MM fittings might be hard to come by for the average guy, so there might not be anyone out there to test this out...
