[RIP]

If I were in your shoes I'd probably do the same thing. Normally, I like to find the smoking gun so there's no doubt it's fixed. You're experiencing one of those times when your not absolutely positive but, you know you have to make a move. Time and apprehension have a way of making you take action. Please let us know how you do. Like most of us , I've never changed a fuel pump on this van. We'd all like to know what problems you came across and the best way to avoid them. Good luck.
