Small Fuel Tube Size for .074 Norvel?
 

Will a small fuel tube size work for a .074 Norvel? My concern is pressure drop.

I usually use medium tubing but I am having trouble getting my clunker to work in a 3 oz Hayes fuel tank. It has a really narrow tank opening and the clunker does not weigh enough to bring the tube down when the tank is inverted. The small tubing is just so much more flexible. I was going to use it for all of external tubing also.

Uncas;

I suggest look at this...

It is made for 1/2a stuff and about perfect for them. Works good as a clunk tank internal tubing.

The Sullivan 1/2A tubing is the best I've ever found. I don't think you will ever run a .074 into fuel starvation at WOT with this stuff. The muffler pressure tap will see to that. The fuel in the line has weight and that weight is influenced by G forces, so stay with the smallest tubing that will get the job done if you plan on flying the plane with reckless abandon. Same theory applies even if you just want to fly like a timid Nun. ;)

Yup, the Sullivan 1/2A tubing is the best that I've found.

This is the best deal I've found for surgical tubing.

That is good stuff, but I don't think it is quite as impervious to glow fuel as silicone. It does make easy to pinch, hard to puncture line for fuel shutoffs.

Ditto, it's the best!
