generally I replace all fuel tubing every year or so......just because

I've had some of the tubing sitting submerged in fuel now for about 4 months. Its just sitting there, still flexible

now, to be fair, its lantern fuel. I don't run gasoline

I've been trying to take a different approach on this forum, rather than sticky stuff that I think is important, I keep the Index, which IS in the sticky section up to date

If the forum ever supports adding thumbnails to the topics, that will be a more clear way for folks too see what the topics are at a glance

Are you still using the Zenoah line in the tank or is it Tygon now too?

great! I'll admit the approach is more complex than it could be, but it works every time and takes one more thing out of the potential problem list

Default Whiplash Fuel tank -- Make simple

Carey,

I am new to gasssrs and have just purchased a Whiplash. I have a question on fuel tank plumbing
I really like the simple setup in this post with
  1. Vent -- with tube coil top
  2. Fuel Inlet –feed line to the carb
  3. Fuel Return -- line from the carb with T

In your Whiplash build thread the instructions are a little bit different and there is a fourth outlet there for “Overflow”. I understand that the tanks can be plumbed in many different ways.

My question is, if I wanted to plumb my tank like this post, can I use the “Overflow” (on top of the tank) for vent and install my tube coil on it?

yes absolutely

if you are using the coiled tube as a vent, attach it to the molded nipple on the top of the tank

then use the supplied fitting as the return line from the carb primer. Plumb in a "T" fitting with a removeable plug. Fill the tank using this

run the fuel pickup/inlet line directly to the carb with no fittings, filters or anything else just a directl line to the carb pickup.

this setup will work perfectly

the 4 connection approach is needed if you are using a one-way vent valve.

Hi Carey,
Now that MA has unfortunately gone the way of the buggy whip, (very sad, by the way), is there anywhere else to source the fuel tank fittings?

I'm trying to complete my Trex 600 Helibug conversion project, and I would like to set up the fuel tank/lines your way....

Thanks for any ideas!

Franz in NJ

Tettra makes fuel fittings, they are commonly used by pattern/F3A pilots. You can get them from Central Hobbies.
