Default Re: Please Help. Rear Engine Is Stumbling.

I believe I've located the fuel starvation/stumbling problem.

This morning I left home with three full tanks. The roads were wet, friction rollers constantly slipping. It took a little longer to reach work.

When I left work, the tanks still had lots of fuel. Both engines never missed a beat, even after two miles of sustained high speeds.

To solve my problem I need to manually pump the primer bulb in the fuel line for 30 minutes, physically siphon directly from reserve tank to each tank...

or install electric fuel pump and small battery.
