[Bmcu] Tech Tip from Roger

How about an in-line fuel filter installed before the fuel pump?  I've 
installed a clear plastic one so that I can see when it is getting 
fouled.  My car is running again but not quite back on the road (still 
dealing with the DMV and a few bits) so I am not sure how well said 
filter will work.

at Liberty Park
