Please don't 'bypass' the stock filter when 'on veggie'. There are so much better/more reliable ways to do what yer trying to do! I know the 2950 sounds like alot of $$ at first, but if you plan to drive it much at all - it doesn't take long to get your money back.

I just returned from a 4,800 mile/14 state trip with my kids and we spent about 3x as much on the engine oil change as we did on fuel! Not only that, but this awesome trip and lifelong memory for the boys was ONLY possible because of VO - since I've only been employed about 2 mths this year...

Oh yeah, since my right foot is no longer connected to my wallet - my fuel economy has likely diminished! (they never clock ya going UP the mountain passes, right! I give them dodges a run every chance I get! )

My VO system components are also OE and better quality from end to end and will easily outlast the rest of the engine!

Good luck!
