Question ?
 

What is the oil pressure gauge supposed to be for a 1946 pickup, 50 or 80 LB ?

OOPS, I meant the sender unit on the block !

Re: Question ?
 

The sender should be the 80 lb. the gauge also should have the 0-30-80 on the face.

That's what I thought. I just bought one that is supposed to be 80 LB and I am only seeing a KS stamp with a 5 under it which makes me think it may be 50 LB ?

If you bought it from a dealer, no way would it be an original 50#. It might be an offshore repop. From a swap meet, you may have gotten lucky and found gold.

The early ones were generally not marked until the change to the 80 psi. After that, they were all marked in order to tell them apart. If it has KS on it then it should be an original King Seeley. They have not reproduced these for many years so the later repo stuff will not have KS on it. You can find NOS and good used 80 psi units on flea-pay but there is always a bit of risk there. Barnfind08 (Southside Obsolete) may have some NOS ones.

I'd say there is a pretty good chance that the one in question is a 50 psi unit. All the 80 psi units were marked as such.

I've got a NOS 80# unit on ebay at this very moment.

Kube or anyone else, If I take a picture of this sender and its markings and send it to you, can you ID it positively for me ?

Re: Question ?
 

Of course, send away.
Check my auction, eBay #113606594702. That will show you clearly what you are looking for.

Your 1946 truck should be a 59A engine and as such, should have a 50# oil pump in it. The 8BA engine that came out for the 1948 F1 and the later passenger car had an 80 # oil pump and thus needed the 80# sending unit. As stated above, the 50 # units were not marked until the 80# units came out because the only unit available was a 50# unit.
