LML Loosing prime, white smoke.

[durallymax]

Been battling loosing prime since we got the truck a little over a year ago. Nothing frequent enough to take it in yet though. The other day though it was puking heavy whitish smoke out the tailpipe. It wasn't super dense like burning coolant but it lingered like unburnt fuel.


Any body else have any issues like this?

I have not experienced this yet only thing I have had is a leaking rear main seal and the day after I bought it I had to have it taken in for a sensor that went bad.

There is a bulletin out stating the filter minder switch for the fuel filter can cause an air leak and loss of prime. The smoke I have no idea on.
