Couple more questions about the vent lines and fuel pump hose to the flame arrestor. They seem simple and "no brainers" but when dealing with the coast guard and sheriff I want it to be correct. I am doing my best to keep the engines clean looking so with that in mind, can I run both valve cover vents to the rear of the arrestor right next to each other? Stock set up is 180 degrees from each other but I don't see the need for that. Also stock is bolted to the top of the arrestor I would like to fasten to the bottom of the arrestor. The second question is about that clear hose from the fuel pump. With the stock carbs it ran to a connection point on the carb itself. My new ones don't work that way so in another tread I was told the clear hose could be run through the top of the flame arrestor? I think a "bulkhead" type fitting with a 1/4" barbed fitting is what I want? Can it be at the outside edge or do they want to see more towards the center? What are you guys doing and would you post a pic for me please. Thanks

I use this (tygon) for the fuel pump to flame arrestor hose:

Like your thinking, I use a 1/4” nipple (with 1/8” pipe thread) into base of k&n flame arrestors instead of their crappy one aimed at thier arrestor / filter media.i may have pics here somewhere ? ?

Ayuh,..... It has to dump into the throat of the throttle,.....
​​​​​​​If into the outer edge, it could spill gas outside the throttle, rather than down the throat,.....
