it has oil in it when u get it...no break in instructions, i would just run about 4 good heat cycles taking the revs up a bit each time then change the oil when finished...How we do all our race motors for years now...
Try drawing from a remote can straight to the pump and see if it will prime and start, also do you fell a suction from the in port of the pump when turning it over?, Is the pump installed correctly? Hope you figure it out good luck!
So I am running from the tank to the in on my water seperator then out of seperator to in on fuel pump which is labeled as the bottom one then coming out the out the top fitting and going to regulator then gauge then filter then carb.
