My Transferflow aux. tanks overfills my OEM tank. Has a anyone had a similiar experience? My fuel gauge appears to be working properly so I don't think it's the sending unit.
I had the system installed at Transferflow last month and I'm really ticked off.

After refueling both tanks and about 20 miles down the road, I looked out my mirror and saw fuel gushing from my fuel filler door. I pulled over and noticed the Transferflow pump was running but my OEM tank was full. I pulled the fuse to stop the pump then put it back in. The pump stayed off. Then for the next three cycles it worked properly. On the fourth cycle it continued to pump and overfill my OEM tank again...more fuel down the side of my truck!

Anyone experience this? I wrote an email to Transferflow, Inc.. I'm curious what they'll say about it. I can almost guess; They'll say it's the sending unit...Dodge will blame Transferflow...here we go!

 

Hey if they complain...... Just put in a switch do it yourself.
