Hope this doesn't make veggie haters not want to help me being I've gone back to diesel.

I've driven about 15k on a vormax fuel filters (R90T) which has a gauge for how dirty/restricted it is. The spin on filter was replaced with a heat exchanger so I only have had one filter. I have done diesel purges every 5k always run diesel with veggie oil and run tanks of bio diesel periodically.

So yes I drove 70 miles with a small plastic fuel filter. I admit it wasn't a smart idea at all.

Is it random that my glow plugs in one way or another went bad after this drive or is it related to praying on a single small filter?
