Question about my new DOS

rjjr1963 · 04/05/2018, 10:42 PM

I have air pockets in the plastic line going from the pump to the tank. Is this normal? How can it be supplying the correct amount of fluid with all those air pockets?

No, Make sure you have the end of the tubing on the DOS real snug. Also if you have an older model they had problems with the pump head.

did you just start up the DOS ?

you may have air until you run the pumps enough to make a clean draw from the source container.
but if you ran plenty of fluid and keep seeing bubbles check fittings and possibly contact Neptune for help.
