DA diaphragm vent questions and methids

[IMAC FANATIC]

The diaphragm vent on the DA's, manual states to run it to " static" air, the closest static air would be the radio compartment or interior of motor box. Anybody actually do this step? And if so, what does the difference make? Have 3 Da's and have done this to none of them, just wonder what you guys do .. If anything, thanks, Brian

LOL. Just go back and EDIT. I will get you a pic what I do....give me a couple minutes.

This works really well but just having a angled fuel nipple hanging down away from inline direct air flow should work fine too.

Thank you, nice solution.

What I've done in the past (thought I had pics but can't find them right now) is to sold the hole closed if it is not in the center of the diaphragm cover. Then drill a hole in the center and tap it to accept a 90 degree glow fuel pressure fitting (point down). Turn that in with loctite and grind off flush with the inside. Then get a length of tygon tubing and a 1" section of 1/8" brass tubing. Use a tube bender to bend the brass tubing to 90 degrees. Put a drop of oil in the tybon tubing and push the bent brass tubing into the middle using an allen wrench. What you basically have now is a piece of tygon tubing with a 90 degree bend in it. Cut each end so one that one end fits on the pressure fitting and the other end stops about 3/8" from the open choke plate on the carb.

I'll see if I can find a pic, but hope this makes sense. Dimes' method works and looks great as well.

I can picture it in my head... I think.
I was wondering if anyone ever ran the thing all the way to the motor box or if it loses static pressure if ran over " X " length.
I usually make something a lot like your taking about but a short section of 1/8 aluminum tube in a 90.

Sometimes, with certain cowl configurations, you may need to run it in to the fuse. If there is no problem, there is no need to do it.

I run mine onto the motor box and just lightly zip tie it there. Easy-peasy!

Thank you pistol, thinking I'm going to go that way this time myself. Makes sense, and easy to remove .
