Filter light on my dash.

[cur.bill]

Can someone tell me where the pressure is measured for the light that comes on my dash for time to change the filter. I have 2 miles on a New filter and the light still comes on and off as I accelerate. I am using an electric pump and I feel that I have plenty of pressure at the filter head as I can bleed the filter just using the fuel pump. It is designed for diesel and it is a new Walbro. This has got me stumped. Thank you.

6.9 or 7.3?

This is a 7.3 non-powerstroke.

Didja check the filter bowl when You removed it? There is a wire and sensor on the bottom cap.

I don't believe there is a pressure sensor. Just a water sensor
