You use a second "T" in the pressure line between the fuel tank and check valve similar to the filler setup and use that to bleed the air out while you fill the tank.

Why?

Just pull the line off the tank.
No need for miles of fuel line and multiple unions.

Why? Because then all the lines can be zip tied or O-ringed and never taken apart. Obviously you have never had a line blow off in flight yet. The pressure in the tank will "blow" it up pretty good, to the point where I've seen tanks split and blow the fuel lines off.

How do you zip tie the filler plug?
Cut it off every time?

And no...I haven't had a fuel line blow off in flight and if I did...no big deal...land and put new fuel line on.

And if a tank splits...what zip tie or O ring will help that?lol....

You dont zip tie the plug, but you can leave enough on the line to cut it off now and then making it tighter. The plug is only one connection, how many others are there in the system that can fail, NONE if they are zip tied or O-ringed.

I get what you're saying but...It will fail at the weakest point if it's going to fail so all the zip ties in the world won't matter...If there's enough pressure to blow ANY union apart,it will blow the fill plug out....FACT...The pressure is identical throughout the entire line...If one union is not zip tied,then none of them need to be.

Use a quality fuel line and replace it regularly.

You can tell if it needs replaced when you pull it off.

I'm with you PJRono, that is the way I go. It does as two new connections at this 2nd T-valve. However, if you zip tie, I don't see an issue. Then once again you have a short section coming off the T that you unplug/plug to fill/fly. This does not a bunch of tubing.

I'm sure that McKrackin's works just fine.

Either way, you have to take something off to relieve the pressure to fill-er-up.

I've been using the following setup for thousands of flights, and I've never had a fuel line blow off.

If I start to notice the line getting soft, I either cut it a little shorter, or replace the line.

No zip ties, or anything else. I like to think it's a pretty simple setup.

I unplug the fuel line at the check valve to vent pressure, and fill through the T.

FACT...The pressure is identical throughout the entire line...
That got me thinking, Why not put a small check valve in the filler line so all the pressurized lines can have tie straps on them and the input side of the check valve wouldn't be pressurized so no need for a strap...

Im an electric goer so there may be an obvious answer to it but if they make small check valves I Don't see why that wouldn't work.

That is a real nice looking setup, Helicrazy.

My layout is similar; not as snazzy...

Another good example! Double banding the fuel line with another piece works just as well as a zip tie or O-Ring!

That really is a nice set up.

Where did you get the mounting bracket and stuff?
