SO I purchased AN fitting kit to pressure test the lines. Seems like when I submerge the line in water, when it's of course pressurized, that I will get some bubbles from the bottom of the red fitting(where the red fitting screws onto the actual hose). That's the fitting that uses the braided outside as threads. It's not like the bubbles are fast, but maybe a 2-3 second delay between each bubble. These lines are pressurized up to 40-60 psi. My question is, should there be NO bubbles at all or what?
 
This is what Parker says about hose testing:

Or to put this another way, I would go right back to the specific brand and part no of the hose and fitttings you have exactly, and find out what the spec working, test, and burst pressure is supposed to be.
 
My thoughts on this is that there may be air escaping from between the stainless braid and the rubber hose. Which could be coming up around that red fitting since that is the end of the braid. How tight do you have the fittings?
 
The other thing is, are the fittings and hose FOR SURE supposed to be compatible?

They are all on pretty good. I tried not to over tighten but to the point where they would not tighten anymore

Don't bet on it, I ordered an in tank sump kit and the hose they sent wasn't rated to be submersed in fuel. I emailed Parker and they said no, I talked to Summit and there response was, "that's the hose that's in all our kits"
