Low Oil pressure

I thought the chain tensioner would blank the oil ports, but i removed the fuel pump too see inside & atatched a drill to prime the pump.
At 5 psi i got a huge gush of oil splashing down on the chain, i would think this is way way too much oil
as i have still installed the bolt with the small hole to lube the chain. the video shows at 5 psi it actualy misses the chain & gets the front cover. I think theres afew psi's there to be had for sure.
I took a little video of it
