What kind of hose clamps would you use on a fuel hose?

worm drive(?) or.....

I have a vw van, and I am going to install a new fuel filter.
The stock clamps are little stainless "rings", that are crimped/crushed a bit on one side.

I guess they work, as that is the way it came from the factory, but worm drive clamps will let me re use them...

Is that a good idea, or should I get the one time use rings?

The fuel lines are "plastic" hoses, and pretty stiff?

Given that you are probably working with a fuel injection system, you must use only fuel injection hose materials and fuel injection clamps. The latter are available as a screw-drive clamp, but they are specially made so that no slotted band contacts the hose and the band edges are rolled. This is to avoid cutting the hose material.
Keystone clamps. Pain in the tuchus.

Too many people who were born on third base actually believe they've hit a triple.

Yes, it is fuel injection, almost, it is a diesel, so the filter is on the suction side.

But I would hate to have an air leak, so good parts will be used here.

I never liked the idea of the keystone clamps, but so many cars have them now, so I figured they are good for something(probably price )

Anyway, thanks!, didn´t know about fuel injection clamps being better in that way.

Price helps, but what actually drives most changes of that nature is the assembly process. It is much easier to design an automated machine that simply crimps a ring than it is to design one that locates a screw head and then tightens it. Also, it is a faster process. Just like the quick-disconnect fuel, a/c, and heater hose fittings we are seeing now.

when i changed mine we didnt clamp the fuel hoses.....not much fuel came out so rags did the trick

keep a container underneath though to stop it going all over the floor

Yep, IIrc, there was not much fuel spilled doing this. This van was sold around 5 years ago.

As usual, thanks Dan, and also cstryker for your comments
