FIRST, you verify that the washer pump is getting proper voltage. Lack of voltage means lack of water pressure, which means the stream of fluid being ********** looks like the result of prostate problems.
NEXT, you look for restrictions to flow--rust or debris blocking the inlet screen of the pump, debris partially-blocking the nozzles, etc.
THEN, you look for LEAKS hidden under the cowl cover. Hoses that aren't tight on the plastic nipples will bleed volume and pressure. Rotted hoses may be porous or split.
LASTLY, verify that the pump isn't worn-out. It's probably original.
The washer system WORKED when the trucks were new. You don't have to re-engineer the system, you just have to make it work like it was designed to.
