@@GOIndustrialthanks for the video. blessings
Good video, Nick! However, at the end of assembly those dog years on the lower intake, housing should be tapped with a hammer to snug that seat up against that O-ring. Bottom housing has a cut, and that O-ring needs to be set down in the narrower part to make sure it doesn’t blow out during operation. Way to go, keep them coming!
Thanks. Just saved me $400
How good! So glad to hear!
Effing great, mate!

Great video ❤ So informative and useful!
Thanks so much! Glad you enjoyed the guide.
My Graco 390 has paint or water coming out of the pump through the G. Any tips on what could be?
Thanks
More than likely one of your packings on the piston has split or warped - this will often cause fluid leaking towards the top of the pump & piston where the 'G' sits on your 390PC. I'd recommend following this tutorial to inspect your packings, or purchase a replacement Endurance pump!
My graco just stopped painting😢
GRACO GURU , need your help brother . Think I smoked it this time . I won’t give back story just straight to the point
Cleaned 395 ball and seat ………. Put the washer back in and installed seat and ball backwards …………..ran airless and instantly knew I put it backwards as it was just knocking weird .!……..I was also changing the suction hose for a hopper like I do for cabinet jobs ………( might be important ) ………… I reverse the seat and ball and it still wouldn’t prime ….. I loosened the lower housing and it began to prime instantly…….. I tightened it again and it stopped priming …… so now it’s got to be on their very loose ( the main housing that holds the seat and ball inside .) im talking really loose , the min I tighten it a little it stops priming instantly ….. it’s not leaking paint though …. What do you think I did , other than mess up badly .
Trouble shooting
When and how do I apply the TSL
We recommend applying 2-3 squirts of TSL before and after spraying. This can be applied with a small TSL bottle to the top of the piston pump - generally where the 'G' pump cover sits. We can put together a separate video on applying TSL if that helps?
