Need to order some fuel line and some clamps. Is there a preference among you pilots? I ask because I've had trouble getting clamps and fuel line that fit well.

I use these clamps from KSJ:

and Aerotrend medium blue silicone tubing for all stuff outside the tank, and Hayes 249 black tubing inside the tanks.

I use the same clamps and after some very bad experience with a manufacturers silicon tubing i buy now high temperature grade silicone from the laboratory manufacturers online here in germany.
As a side effect you get 20 feet for the price of 3 in a model shop.

Thanks. I have the Hayes for clunk lines. I've used those KSJ clamps before. I think the Min Air fuel tubing I bought was just too large OD for them to work well. I bought the Medium fuel tubing, and it's pretty fat for the clamps.

For external plumbing I use Prather medium fuel tubing and have never used clamps. I considered clamps when I installed my YS60SR because it uses crankcase pressure rather than muffler pressure, but didn't install them and have not had a problem.

I use the KSJ clamps to prevent the carb from getting flooded when filling the tank.

KSJ makes the only decent clamps. Airplane guys are always getting them from me.

Prather did go out of business, however, Hyperperformance Products picked up some of their product line and has had their fuel tubing available for years. I've personally ordered it from them several times over the years. I provided a link in my post above. Here is their contact information:

KSJ clamps are the best.

Sullivan fuel line for both the inside and outside of the tank. Never had Sullivan line fail, and boy does it stick to the nipples.

Is it old stock or new stock ? The last 30 feet I had was not so good as it used to be in the olde days. I bought it just before they went out of business.

All I can say is I've ordered from Hyperformance several times over the years and it looks identical to the Prather I used to purchase from Tower. I don't think it would be possible for them to enough old stock to last all these years. I think Prather went out of business in 2006 or 2007.

Thanks for the input. I am always hesitant to use fuel line which comes with a kit. I always heard to scrap it and replace with quality line. Thanks for the reference on Prather line.

As for clamps, I think the KSJ clamps will be the deal for fuel shutoff. I've never used clamps to secure the line to the barbs. I have some of the spring wire types, but fear they might cut into the tubing.

Ace Dude - do you use the medium size line on helis?

Yes, I use medium size. You can always use a piece of tubing as a clamp as well. Just cut a small piece of tubing and slip it over the end you're placing over the barb. A hemostat or needle nose pliers will help you slip the outside over the inside piece.

PM me your aaddress and I'll send you a small piece of Prather to test fit with.

To secure the fuel lines you can use small cable zips (not too tight) or the special ones Vario Helicopter sells.

i use those in the FAI birds i build.

Thanks, RR62. I've also used zip ties on the clunk attachment barb inside the tanks in the past. I didn't plan to run anything on my external plumbing. I saw Tim Jones using a short second piece of fuel tubing fitted over the connection too. I think that would be ideal inside the tanks, but it's difficult to get the short piece on the outside of the main line.

I have a KSJ clamp and fuel tubing left over from a couple of years ago. It seems to work fine, so maybe I'll use the KSJ's for shutoff points.

+1 - Medium clear fuel tubing. Pretty simple stuff. Just make sure its not stiff as hell so your clunk is floating in the tank. Needs to move.........

The second piece of fuel tubing works great. I use a small pair of needle nosed pliers to expand the ring, then slide it over the fuel line.

dkshema: Yep, I did the same.

devin120: I won't use stock line in the tanks. Hayes is the go to for me there. I pre-swell it in fuel for a couple of days before cutting it to final length. It's very "slinky".

I will test the idea with the second piece of fuel line.
But i use 3mm fuel line and thick wall type, so the same one might no do the trick.
