Seneca fuel issue

[jjay]

My wife and I own a 2014 Seneca and just noticed that very little fuel is consumed from the passenger-side tank. The low-fuel warning light comes on when the driver-side fuel tank falls below 1/4 full. Have any of you experienced this and is it an easy fix?

There is no crossover pipe or tube. This is a dual feed dual return system. Air bubblews or kinks in the lines will stop the meager transfer.

No cross connect on Senecas, they use an Equiflo system to level the tanks. There are small tubing vent lines that come off the top and run down on the inboard sides of the tanks (towards the frame rails). If they get clogged by a wasp nest or other debris you will experience your issue. Less likely there is a leak in one of the fuel lines causing it to suck air and not self-level.

This quote is from the Installation Guide - Return Flow Splitter

"Equalization: If full of fuel (bubble free), the lines will act as a siphon
to level the fuel in the two tanks, just like a crossover line. An
air bubble can break the siphon if trapped in an upward loop, and
stop flow from one tank."
