I think the issue is the shorter hose is the path of least resistance and thus has higher flow.Shouldn't be necessary. Most washer nozzles have a spring loaded check ball in them to maintain prime for a reasonable amount of time. Otherwise you'd dry-swipe the wipers frequently as the hoses would empty back into the reservoir.

If that is the issue, make the hoses the same length by having a hose off the pump to a tee, have two hoses from tee that are same length and then to squirters. May have to coil the closest hose from pump.I think the issue is the shorter hose is the path of least resistance and thus has higher flow.
That is not how fluid hydralics work. once the lines are full any pressure/flow is equally transmitted to both lines unless there is a restriction.I think the issue is the shorter hose is the path of least resistance and thus has higher flow.
Square body trucks had a TSB to add a check valve in line by the washer tub and the later ones had them factory.I would imagine the gmt 400 probably jhust continued this trend, post/in the pump and and keeps prime in the linesShouldn't be necessary.

Interesting on the retrofit check valve! All I can remember about squarebody wipers was I experienced a lot of them that refused to shut off.Square body trucks had a TSB to add a check valve in line by the washer tub and the later ones had them factory.I would imagine the gmt 400 probably jhust continued this trend, post/in the pump and and keeps prime in the lines
I think that would be true in a rigid pipe but not a soft hose. But I am no engineer.That is not how fluid hydralics work. once the lines are full any pressure/flow is equally transmitted to both lines unless there is a restriction.
Yeah they don't like being frozen at all. I add a half of a cup of 91 percent rubbing alcohol to my washer reisevor every year before it gets cold out and every time that I have to refill it in the winter. Just make sure that you run the washers long enough to get the alcohol into the small lines and out the squirters.Every time I have a problem with the washer jets on my '88 K1500, it's because the hose has popped off the nozzle, or has gotten so stretched-out that it doesn't seal properly on the nipple it's pushed onto.
And I've replaced several washer pumps on my various vehicles due to poor or no output. I have a suspicion that they don't take kindly to having the washer fluid freeze inside the pump.
