You can get oil pumps and pick up tubes at Mancini Racing...
I've also bought pick up tubes at my local NAPA for $20....
I like high volume high pressure oil pumps... If you get a Melling oil pump, they come with a 72 psi spring... The MP ones are lower pressure stock (around 55-65 psi) , but you can get a high pressure spring to bring it up to 75 psi... But if you buy the Melling HV pump, it comes standard with the 72 psi spring...
