changing oil in my 48 fleetmaster canister oil filter 4x4.75
any matching napa number ?

IN 1948 there wee more than a dozen diffeent oil filters sold for installation on Chevrolet engines. Remove the old filter and look for ID numbers or brand name.

gene u are hard to beat . after two hours of drip time and several paper towels, in fine print Wix 51006

Then go to a NAPA store as NAPA filters are WIX and follow WIX numbers.

It will be a 1006 at Napa. Their first run filters are Wix. Same filter at Carquest or Big A. If they're still around...Joe
