Gas tank plumbing questions

rcflyer · 10-15-2007, 12:01 PM

Hi guys, I have a couple of questions on the gas tank plumbing for my DA100:

1) Which is better, 2-line or 3-line tank? Will a 2-line setup cause any carb leak during fueling?

2) I am using Hayes neoprene inside and outside the tank. The tubing is very flexible and I think I will put a brass tubing between the clunk and tank stopper to prevent the clunk from hitting the tank front. My question is how long should the brass tubing be in a 32oz Dubro tank?

Thanks!

Read post #2 of this thread the proper way to set up a gas fuel system(THE SAFE WAY?) This is how I do it.

that and you will find about 50/50 on 3 line vs 2 line in a gas engine.

I use both ways, but I make sure and have a good filter between the tank and the motor. Like Temptation said, read the post.

How long should the brass tubing be inside the tank enough to prevent the clunk from flipping forward?
