Gas tank Clunk line
What do you use for the clunk line??? Tygon??
I drain my tank after flying and every season end up with a stiffy in the tank!!  Some say to leave fuel in the tank...but that stinks.....  So have any of you rocket scientists figured out a better clunk line?? Or are you doing the clunk line mambo every season , too?? Last edited by bosshoss; 03-12-2007 at 01:47 PM. Reason: typo's |

Re: Gas tank Clunk line
I swap out all of my gas lines every year. Some lines have still been soft and just like new and others have been really stiff. IMO it's alot cheaper and safer to spend 5 bucks and change it out than it is to loose a plane to a failure. And if you pull the tank apart to inspect it, might as well just replace it as long as your in there.

Re: Gas tank Clunk line
The best:
http://www2.towerhobbies.com/cgi-bin...&I=LXK824&P=ML Just make sure to put a section of brass tubing in the middle of the clunk line. It's pretty flexible stuff. |

Re: Gas tank Clunk line
I've switched from Tygon to Aerotrend (the blue fuel line). Doesn't harden like Tygon does and it's semi transparent. www.aerotrend.com

Re: Gas tank Clunk line
I too use Aerotrend fuel line. They have a line called "EZ FLEX" I have never had this stuff stiffen up. I use it on the clunk line as well as a secound line for filling and empting the tank. I also feel that using a tank over 24 ozs and having a felt cluck on the end of the pickup line, there is no chance of the clunk getting stuck anywhere in the tank. I also look at my fuel line each spring as my season starting maintenance. Works for me.

Re: Gas tank Clunk line
I have always used 5/32 line Tygon, is the 1/8 blue line what you guys are using for the 50's and 100's??
I have so many lines to replace I am going to buy a spool... |

Re: Gas tank Clunk line
The 1/8" is fine. The phone number for Aerotrend is on the website if have questions. I bought a spool because I was tired of the Tygon getting hard. It's about a dollar a foot, but worth it. Easy Flex is what I have as well.
