What's NOT mentioned is how to REMOVE the German braided fuel line of the carb or pump. Too many people YANK it off the inlet/outlet pipes on the carbs and fuel pumps.

Yes, some folks will wire the fuel line clamp to a screw on the carb or pump to help insure the pipes don't fall off. However, simply using a razor blade to cut the fuel hose length wise when removing it will help tremendously as well.  |
The thing is you don't know what the P.O. did to remove the hose, that's why you safety wire them?

Yes, IF I'm not doing hard lines, which I almost always do no that I have a lot of tooling for it I put the tube in the flare tool about a 1/16" proud and flare that little bit, makes a huge difference. Make sure the edges are smooth though or you'll gouge up the hose getting it on.

| I use the band style/fuel injection clamps. If you get the right size for your hose, they will not be over tightened. I also use fuel injection hose, way more expensive, but holds up great. |

Besides proper clamps, there is a proper hose to be used with fuel injection. I run a CB FI/Turbo system, and at idle produces 45-50 lbs fuel pressure. When you buy fuel hose, they should ask you NA or FI along with the size and length.

That settles it.
I'm going to clamp the entire fuel system.
I will not put the inline filter in the engine compartment.

McMaster Carr has a lot of different clamps as well as searching Ebay.
I am not a big fan of the woven outer German fuel hose with Ethanol. Look into some of the Gates hose that works with the blended crap fuel we have. |
Lets be clear here.....because when people do a search on nuggets of information......they may not bother to read important details like....APPLICATION.
Spring clamps are excellent for carburetor fuel lines.....but are NOT to be used with fuel injection.
If you get a split in the inner plies of the fuel line in a fuel injection system where pressurized fuel is traveling laterally between plies......which is very common.....the hydraulic pressure can literally defeat the spring pressure and cause a line to blow off.

I looked at 2 styles of clamps. One was an upgraded work drive and the other was a band clamp. Both were stainless steel and both had rolled edges so they don't cut the hose.
I went with the ABA band clamps.

In Ca. here and the German cloth lasts only a year sometimes 6 months. Hose clamps will hold the piece on underneath but not the hose.  I usually only use on the pressure side. I changed to SS hard and ptfe. I was tired of changing the lines. |

Yes, this. The fuel line weakens and can slip off under pressure.
You really don't need it on the inlets since they are not under pressure but it doesn't hurt.
It depends how often you check your lines.
If I am using the woven lines I check them once/year.
In the olden days you had to cut the ends of the German woven lines to get them off - that is how well they worked with old quality lines and non-ethanol gas. Even so, VW added clamps at a certain point.

Yes, they clamp all the way around the hose without digging into it and tearing the rubber. They are used primarily on fuel injection systems so if they can hold 60psi 3 psi won't be an issue

Is the pressure generated by the fuel pump not enough to cause the line to leak. I was surprised to not find any clamps, starting at the fuel tap, inline filter, fuel pump had one at the intake, no others.
Like I said, some do and some don't. Are hose clamps a good idea on fuel lines?
Or over kill?
