High Pressure Fuel Hose Clips
lsdweb - 25/7/06 at 11:27 AM

Hi All

I'm plumbing my rubber fuel hose in and the local mtor factors reckon 'normal' jubilee clips will be OK. I've read somewhere that there are special clips for high pressure rubber fuel hose.

Obviously, I don't want to get this wrong!

There is a lot of bull talked on here about the "correct" clips.
Mine passed SVA without any comment using standard stainless jubilee clips.

correct, there is an awful lot of bull about these clips.

They just need not to damage the reinforcing cord in the hose.

Second that.

A good quality jubilee works fine on mine and no problems with MR sva.

he was more woried the the pipe was of the correct grade. he did feel arround some clips to ensure they were not leaking about to pop off.

Double up on jubilee clips for extra safety. That's what I'm planning on doing when I get some FI hose

another "depends on where you go"had to have hose clips not jubs on mine

My SVA Tester actually said that it's because Jubilee clips don't stay round when you tighten them below a certain size.

Hence the sealing pressure may not be even around the pipe/hose junction and MAY be a source of leaks.

.... it really does depend upon individual testers IMHO.

I used fuel pipe clips.

I worked on the principle that I might as well use the correct clips - they only cost a little more than ordinary jubilee ones. this made one less thing to upset the tester.

They do work well, as a bonus!

If you use the wrong size Jubilee clips then this becomes an issue.
If you use the correct size then it's not.

I would personally contest and report a tester that failed an SVA on this. These people are public servants not frggin dictators!!!!
The SVA manual only refers to things being "Fit for purpose" Jubilee clips have been used in industry for donkeys years on hoses that carry a fcuk site more pressure than a piddling little fuel pump.
As stated above though, they must be the correct size.

I went for the 'proper' type in the end as it seemed easier to do now than after the car was finished and I'd failed SVA.

As David says, for a few pence more it's hardly worth a fail.

Interestingly, on my Golf all the hoses are jubilee clips.... apart from the fuel ones!

So if VW use them that's good enough for me!

Cheers,
James

Thanks Guys

I've used jubilee clips and everything is OK - one small leak but that was where I hadn't screwed the pressure gauge into the adaptor far enough.

I ran the pumps and got 2.8 bar at the fuel rail. This has dropped to about 1.5 bar overnight but that's probably the relief valve releasing it back to the tank slowly.

It all looks like this - a bit confusing and cramped (behind the seat back) but necessary.

I've left the system for a week (been on hols) and there is still over a bar pressure so I'm happy I have no leaks.

Thanks for the help guys.

Unless you had used the wrong size jubilee clips then the tester was spouting a complete crock of shite.

They stay acceptably round for the size range etched or embossed onto them, that's why its written on them!

Someone's probably changed them all before you then, because VW like to use those 'orrible spring clips on all the hoses (the ones that seem like a good idea to remove with monkey grips, until they ping off). And on my Golf all the fuel hoses were terminated with proper crimped on fittings

Jubilee's are fine as long as they are the right size, and as long as they are clamping down on something solid under the hose (i've seen engine conversions where the 'tuner' had put push on hose over a plastic fuel line and tried to clamp a jubilee over that, crushing the plastic line )
