Actually Richard, the Afordable filter will filter almost all the oil before it goes to the bearings. With this system, the oil is pumped up past the distributor drive and into the tube which leads to the front of the valve chamber where it is picked up by a tube and run through the filter and deposited back into the chamber where it would be in the original system. The only oil that escapes this is the oil which bypasses the tube and is leaked (for lack of a better word) past the cam gear into the chamber and back into the pan. This is the best system in my opinion because of this. Some will not like it because it won't filter 100% of the oil, some just won't like it or any type of filter because of just any reason they can think of. The last word is, if you think it works, wheres the harm except to your wallet.

Also, the Model A pump will make plenty of pressure but, in the original system, there is no restriction to make pressure until that restriction is introduced into the system. Adding a filter will add a small amount of restriction because of the anti bleed back valve built into it. This will most times cause your gauge to show a couple more pounds of pressure.
