  have assembled stock 46 V-8 for 41 3/4 ton pu. Have oil filter set up from a 41 or 42 V8 with the lines missing. How are these plumbed? Thanks.

  Here are the instructions for late 1940 - 1941 oil filter installation.

  I didn't see a mention of a restricter fitting in the instructions. It was likely included in the kit. If not, The fitting in the line to return the oil to the pan should soldered shut, and a 1/16 inch hole drilled in the solder. This is a bypass style filter, and if the flow isn't restricted, it will adversely affect the oil pressure to the bearings.

  Note the instructions posted above are for 40-41. Its shows the filter return line snaking up to the front of engine where it goes into the engine via a banjo bolt replacing one of the distributor's bolts into the block/sump. Kinda Rube Goldberg-ish. And that line and banjo bolt will be tough to find, is not being reproduced. But you shouldn't need to do that. Your 46 oil pan should have a fitting on it to receive the filter return line, which will make that part of plumbing the filter much easier.

Here is an excerpt from a previous discussion on how to run the oil filter return line. This was posted by Mike Kubarth, the club's adviser on the 1940 model:
"...........All oil pans, 1941 - 1948 had a return fitting integral of the oil pan. 1941 pans had a fitting near the left - front of the pan. 1942 - 48 had the fitting integral of the dip stick tube boss.
If you have the later pan in your '40, I'd suggest you take advantage of that pan fitting."

  Thank you so very much.

  Be 100% certain you heed Super's advice in regard to restrictive fitting. It MUST be there or you WILL lose oil pressure. Originally it was integral of the pressure side. However, I suppose it really wouldn't matter which side it was placed as long as it is present.
