well i screwed up this time.....i pumped what i thought was good diesel from a storage tank,it turns out water got in the tank and ended up in my tank....WIF light lit and check engine light....i drained the tank and pumped 28.5 gallons of diesel from the gas station and put additive in my tank..i cleared the computer and drove the truck less then a 1/2 mile when the check engine light came on and then the WIF light came back on....i used the T and drained some fuel ...it looked good and the WIF light went out.....then i drove the truck 45 miles and it ran fine at 55 mph but at 45 mph the tach was at 1500 and she would buck..i gave it more throttle and it cleared up...the check engine light came back on the code is po251 injector pump metering cotrol A malfunction.. should i run this tank threw and fill it again???

Depending on how you drained the tank, you may not have gotten all of the water out. The water will be at the very bottom of the tank. You may need to remove the tank to completely clean it out. Sounds like there is still some water in the system.

most of the water dispersants just attract to the water and make it fall to the bottom of the tank as gunk. its still there and will cause tank problems later.

hopefully nothing hit the IP, a bit of water causes wear, fast

definitely need to drop the tank. I drained mine with the pump till it stopped pumping, dropped it, and dumped 2 gallons of fuel out of it.

Similar question, don't mean to hijack the thread too much. My dad just accidentally dumpped less than a quart of water in his diesel tank. He noticed and hasn't started the truck at all. What do we need to do to prevent any future problems?
