The merits of the "Rocket style" fuel vents

[szicree]

Any updates, positive or negative, regarding the coiled fuel vents in the wing roots used on Rockets. I'd love to avoid that crazy vent line running all over my cockpit.

Got them on my -8, got about 60 hours on it now, no problems. Only regret I have is that I didn't find out about this idea before I fought to put the vent line tubing in the gear towers.
Great idea as far as I'm concerned!

Not familiar with the coiled technique. Can you elaborate or provide a link?

Thanks,

Larry what you do is coil the vent line and secure it in the wing root, the area between the inboard wind rib and fuselage. The long tube length handles the overflow and prevents siphoning. I am a little fuzzy after that, but believe you just run the vent out wing root fairing.

To me the fuel vent must:

• Will not easily siphon fuel out the tank

• Provide positive pressure in the tank

• Not allow fuel vapors in the cockpit

• Not get blocked (bugs or ice)

If it does all the above, than Yea Verily!

I don't find the per planes vent line too onerous to install, but to each his own. I get real conservative and less brave with any mod that affects a major system, like the fuel system.

One thing I would say is a must, is you vent to the outside. I am not sure as I said but think the Rocket method (coil in wing root) may not vent out and just terminate in the wing root. Not sure how they do it, but that's a bad idea and could potentially lead into fuel in the cockpit in my opinion. G

Here's a full thread on the rocket style fuel vents.

the wing root vents work great, as good as the standard vents, and they are a lot less work. Also it gets more fuel lines out of the cockpit. I have installed them on two aircraft, another one shortly. Credit for this idea goes to Mark Fredrick from Team Rocket. http://www.teamrocketaircraft.com/

George, George, George....We're not as dumb as we look! The vent line is terminated just like Van's design. I used an AN fitting in the bottom of the wing skin that overlaps the end rib.

Randy, Randy, Randy, no one said you are dumb. You seem to be very sensitive to my post? I am so sorry if I offended you, the Rocket community or who ever else you referred to as "We're". You're smarter, so forgive my ignorance. You seem to be very proud (defensive) of anything "Rocket". For the record if you read what I wrote I did not say this vent would not work acceptably.

In trying to help I clearly stated TWICE, I didn't know all the details past the coil in the wing root. BTW I have seen "internal vents" before (not associated with the so called Rocket vent), and they seemed to work well on those aircraft. I did not call anyone dumb than either. Chances are they're smarter and no doubt the fuel vents meet criteria. Its just my opinion that you can't go wrong by going per-plans (Vans Aircraft). Call me crazy.

I stated, IF its terminated in the wing-root (of a RV) it could get into the cockpit area. I find your response intentionally condescending. I'd like to hear your opinion about facts of the topic, an intelligent debate instead of your animosity toward me. My late mother gave me advice long ago; "If you don't have something nice to say about someone, don't say it". Try it. Peace

Yikes George, I wasn't offended by your post at all. I was more making a joke of it. I guess I should have put a million smiley faces on my post so you wouldn't go over the edge.
