The Stovebolt Site Forums The Parking Lot Big Bolts 48 oil filter

Got a 48 that has the oil filter mounted on the inner fender. Engine was replaced at some time with a mid 50's 6cyl (so I was told by po). Oil lines were never hooked up. Where do they hook up to the engine?

The supply line to the filter attaches to the side of the canister about halfway up and attaches to the engine on the driver's side with a "T" fitting to the same place as the oil pressure gauge line. The return line from the filter to the engine comes out of the bottom of the filter housing and attaches to a port near the oil pan flange on the driver's side just ahead of the supply line. The supply and return ports in the block are close to the exhaust pipe, so be careful how the lines are routed. Since your filter canister is mounted on the inner fender, be sure to use flexible lines from the engine to the canister. The pre-made lines sold by various antique parts vendors will probably be too short, since the usual mounting position on smaller trucks is on the intake manifold. Any hydraulic shop should be able to fabricate custom-length lines suitable for engine oil.

Thank you!

If I put a T on where the pressure guage hooks into, and the return line just dumps back into the sump, right? Will there still be enough pressure from the filter to make the guage read correctly? Seems to me that the circuit through the filter will pretty much be "free flowing " making the guage read incorrectly or not at all.

Any thoughts?

Thoughts?

The return line goes back into the block.

Jerry gave a correct description.

Here is an installation instruction sheet.
