Heres some food for thought using the 80# pump will not give you more flow. If more flow is what your after than the Melling M-15 HIGH volume oil pump is the one to use. Now I know theres going to be a flood of comments that the M-15 pump should not be used however. The decision to try a pump for more flow will only be accomplished by installing the M-15. And to add to more comments heres what you should do with your front pressure relief spring area. Place a small ball bearing in the chamber doing this will close off that front oil leak complexly. Use the plunger {the stem will need to be shortened slightly so the cover can go on} and spring to hold the bearing in place. You should see a slight improvement in your pressure reading. And the answer is yes to the question have I tried this myself and I can say no flatheads were harmed in any way during those experiments. As a matter of fact they all have survived rather well.
