Fuel Line Clamps

[Coolerman]

Doing a bit of research on fuel line clamps.

Types

Worm Drive: Cheap. These are the the slotted worm drive clamps that are available by the back at Auto Crap, always give you a cut because of the end sticking out, and they have a tendency to cut the hose when tightened too tight. Hard to remove in tight places. Ugly as sin.

Worm Drive: Expensive. Rolled edges so won't cut hose as easily. No exposed end. Good clamp. Also hard to remove. Still ugly.

T-Bar Clamp: Expensive. Similar to the OEM Toyota wire clamps but uses a band instead of wire. No exposed end. Easy to remove and re-install as you don't have to completely unscrew it. More OEM looking.

Plastic ZIP TIES: Yes, zip ties. Found out that Evinrude uses them on boat motors for all the fuel lines. (This makes so much sense I'm going to try it. ) Make sure to use the metal locking type that are UV stable.

Wire Spring Clamps: Cheap. Easy to install and remove but will cut into the line if they are the wrong size. Not for high pressure. (4 psi should be fine)

Wire Spring Bands: Cheap. Used by a lot of OEM's. Easy to install/remove/. Look OK.

Permanent Crimped clamps: Cheap clamps but requires a crimping tool. These look totally clean but are not easily removed.

Pros/cons?

Getting back to the zip-tie thing, T&B Ty-Raps are steel-banded/UV-stable and come in handy for many things. Fuel lines may be one of those things...

I like ratchet clamps as well.

And get the tool that pulls them thight. Great invention

I have the tool, use it in my business. I just tried the zip tie thing on a piece of fuel line.

Laugh not at my pink zip ties... I'm at home and all my work stuff is, of course, at work.

As you can see, just using my hand, the zip tie has compressed the rubber tube quite nicely. There was no ferrule on this section of hard line, so with a LOT of effort, I was able to pull the rubber tube off the line. I believe with the heavy duty black ties I use at work, along with the tightening tool, this will work perfectly.

Mark, I used zippers on my fuel filter mod. Granted, no pressure there, but as long as they hold....

I use the Type 430 and Type 316 Stainless Steel Nonperforated Worm-Drive Hose and Tube Clamps found at McMaster Carr. They are the best I've found and I've never had to replace one because of any type of failure.

Clamps from Aircraft Spruce


I like these kind cause I can take them off in the dark with freezing fingers and nothing more than maybe a pair of pliers not as fiddly as the screw type

zip ties are a great idea for the trail spares list I don't see any reason why they wouldn't work if you use the gun tool but removing them might be tricky in some spots

On the early Cruiser Toyota had NO clamps at all, everything was screw on. Then at some point they went to the hard line attached to the frame and used clamps on the hoses at each end (from the tank and to the filter).

Mine had cheap az worm clamps when I got it.
What were the Toyota clamps for those connections? Small wire clamps?

Bsevans I looked at those stainless clamps. Maybe I should use the titanium clamps to save some weight...

My 72 had the braided covered hose with no clamps. It used the nuts (similar to an AN fitting) to attach to the hard lines.

Got a pic of this?

Got a pic of this?

I can take one for you this afternoon after work. These connected to the hard line coming out of the tank, to the filter, to the fuel pump, and then to the hard line going to the carb. The PO had them all disconnected and rubber hose running to an electric pump. The lines were clogged with dirt and junk but still somwhat intact.

 

[Coolerman]

Oh NOW I understand. No need for a pic, that is exactly what I am hooking up now. I misunderstood, I thought you meant the flex hose screwed onto the hard line on the frame.

bulkhead fittings

Bulkhead Union,Stainless Steel Union,Bulkhead Tube Union,Steel Bulkhead Union

One idea if you want to go from hard line to hose and use fittings is to add a bulkhead fitting. This could go on the body or frame or be mounted via a stand off clamp

these come in male or female ends and you can get metric might look nice to go from braided hose to hard line

fuel line qd's

Not in my budget to start on this little stuff till the main work is done but I thought these QD's were pretty sharp

Mine looked very similar to these all around but the hard lines were flared and coupling nuts attached the hose. It looked like the factory line that SOR shows but all mine were done in this manner. I think the PO did some "custom" work.
