2001 Isuzu NPR Box truck

Hello! Welcome to justanswer!


Fill the filter to the top with fuel then install it.

would the wrong filter prevent the truck from starting?
No, it wouldn't fit if it was wrong. Putting an empty filter would cause a serious amount of air in the system. Fill the filter and repeat as many times as necessary to get it running.

so i shouldn't need to prime the line. I had to do this when I ran out of gas. So pull the filter back off and fill it and then reinstal and then try to start again?
