2. melling sells two press in pick ups 22fs and 22fs1 i cant see or tell any difference between the two is there a difference and what is it ?
3. what is the best way to press in the pick up screen ? just push it in by hand ? any loc tite or anything on it ?
4. and lastly should i shim this oil pump some old threads showed many people shim the pump one measurement i saw was .150 which is about 3.81mm is that good ?

This is not to be construed as contradicting Mark, but I shimmed mine with a ¼" nut (or was it 10mm?) and my relief pressure went to 60psi, but my engine DOES have loose clearances.
Please note that increasing the oil pressure and/or volume requires the engine to do extra work, so doing so will slightly decrease engine output and fuel mileage.
