Constructed this a while back this summer. Gets the job done. Cost about $10 depending on whether you have a little breather filter already or not. $5 for a crappy little APC breather, $1.50 to $3 for the cheapest inline fuel filter you can find, go to NAPA and ask for the cheapest one they have, and about another dollar or two for some decent vacum or fuel line that is the appropriate size.

 

just follow the red line

 

from the valve cover using about the first 5 of the eight inches of fuel line

 

towards the firewall at a slight downward angle connecting to the fuel filter at the lowest point

 

and up to the breather using the remaining 3 inches or so, just whatever looks right for you but these are pretty much the lengths I used. I just zip tied my breather filter to some nearby loom.

 

I change the filter every other oil change. here's an old one compared to a fresh one.
