Hi snurckle. If you are talking about the two line system that I pictured in post #10 and Opjose has shown a neat device for then The answer to your question depends on the engine mounting orientation and muffler type.

If the engine is mounted sideways then the cylinder head in on the right side and the stock muffler will protrude to the right bottom and the pressure nipple will be exposed It can be removed for fueling just like a trainer. In this set up the engine cannot be hydrolocked by some accidental flow into the muffler since it is below the chamber if you should forget.

If the engine is fully inverted with a stock muffler or tuned pipe it will be on the right side and agine the pressure tap will be exposed In this case you must not forget to remove the pressure line or overflow will go directly to the chamber hydrolocking the engine.

If you are using any form of completely inaccessable muffler or some type of Pitts then the pressure line is passed out and in the cowl just like the feed line and also provided with a split so it is easily separated just like the feed line to check your overflow just like a trainer. It can be on either side of the cowl.

This is the most trouble free fueling system possible and yes its just my opinion. I use it on everything even on exposed engines with rear needle valves.
