239 v/8 on the bottom of oil filter there is a tee that screws into canister oil sender screws into to one hole oil line from top back of block goes into other ,my question is why does the tee have such a small hole for oil to go into oil filter would a larger hole make oil pressure reading off,i have 2 others and they are the same,can anyone explain tome thanks clyde

 

Is this a flathead 239 V8 or a Y-block? I can't figure out what you are describing, but on flatheads the Tee is at the inlet (upper connection on side of canister) and the gauge sender is in the branch. The filter is a bypass or side-stream filter and is not intended to flow a lot of oil. There is a restrictor orifice in the inlet of the canister that MUST NOT be removed or drilled out. The connection off the bottom of the canister is piped down to the side of the block, that is the return line.

 

thanks ALBUQ F-1 i had a senior moment and switched connections at any how you answered my question its nice to have knowledgeable folks to get answers from; thanks again clyde
