|
|
I have noticed that some do and some don't (put hose clamps on fuel lines).
I'm using the braided German fuel lines.
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?

VW thought so, that's why they put Ottiker style clamps on all the fuel lines at the factory.
The "finger puzzle" reasoning doesn't work on me, shure it's hard to pull off, but it still offers no resistance to internal pressure pushing it off from the inside.
No doubt there will be other opinions, this subject is like where to put a filter or what motor oil is best. _________________ Rust NEVER sleeps and stock never goes out of style.

My opinion is if you think it's worth the chance of the fuel line coming off the don't run hoseclamps to me it's not worth the potential fire |

Always use clamps on fuel line connections. |

The ethanol in our fuel line chews them up faster than fuel did 50 years ago. They need to be clamped. |

Those clamps are good since they are smooth on the inside and won't dig into the hose like hose clamps you get at your local hardware store.
There are spring clamps that are good as well as the crimp on ones like OEM.
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. |

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

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. _________________ How to Post Photos

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. |

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. _________________ Glenn

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.

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