Hey everyone...dumb question....

Do different size engines require different fuel tubing sizes? I just noticed that I've got two different inner diameter size fuel tubing lines. Is the smaller size generally for .12-.18 engines and the other for .21 and up or is it safe to use the smaller tubing on a .21?

Thanks,
Tony

Yes, but there are different sizes. I learned the hard way trying to replace the fuel tubing going into my tank with size "jumbo", as opposed to medium.

Size medium was a lot easier to install and maintains a tight seal.

I've got a question about tubing too. Does the length matter. In my old engine it seemed like when I cut the tubing short I had problems. The engine was almost dead so I don't know if it was my imagination or not.

Can I cut the tubing as short as I want with no problems?

fuel length will have a effect on run time, the shorter the less runtime. More fuel tubing can hold more volume, after getting mill up to temp(with long fuel tubing) refuel and you will actually be holding more fuel than legally allowed. But on the negative side, longer tube can also hold more air.

Fuel Length is the difference.

the dubro large tubing for airplanes. It helps get max fuel when needed. If you have a clunk tank then medium. You can get a huge 30 ft roll of it for 25 bucks. It will last forever...

Hi.

Remember that you need approx. 20 cm extra tube to have 1 ml more fuel.

Allways use the same inner diameter tube all over. Otherwise you can have tuning issues.
