Isuzu NPR fuel filters replacement 

The prime pump on the water separator works well enough to avoid the hardship and spilled fuel of trying to pre-fill the secondary filter. Just pump until firm then let the air out of the bleeder and close. Pump until firm, let the air out and close. Repeat until a little fuel comes out of bleeder. Never took me more than 3 cycles. And ALWAYS wear gloves. Certain additives in oils/fuels and hydraulic oils will absorb into your skin and NEVER leave! I am lucky to have only lost feeling and softness in my fingertips. I know an old retired machinist that can no longer close his hands.

You guys are awesome, and make a wonderful team. Thanks for the video very helpful.

Thanks a ton for this video, it was super helpful! Do both filters need to be changed at the same time? Or, is one more frequent than the other?

You make him do too much work. Poor guy 💔
