I primed the oil pump & spun it when it was first set in the truck last spring. Oil flowed at the outlet I am useing for the gage & flowed to the lifters very strong.

My two concerns are the motor losing oil pump prime setting for several months .

And the right ways to use the oil ports. I want to use an oil gage & no filter. Will It do any harm to the oil flow or presure to plug everything except the one hooked to a gage (It is low & to the rear of the block).

Thanks, Kelly
