temp fix for pinhole in injector line.

[homerj1]

Hello,

I have a small pinhole in one of my injector lines on my 1.6td.  I also have a 12 hr drive home on Sun. 

I was thinking of splitting a 2 in long section of small  tubing, then a larger dia  fuel line over that, then some triden clamps.

Will this work? 

thanks

no... i used my tig to fix one though 1 time... but i spliced 2 lines in a solid area.. pin hole = thin so no strength left..

[homerj1]

Maybe, I wasn't clear.

I was going to put the 2 layers of diff. dia rubber line ON TOP of the steel injector line, not use it to connect the 2 parts of the line.

Sort of like a Band-Aid. 

or else it will be a leaky smelly drive home

Do you really think that hose clamps are going to hold 1500 psi? Tig it up or get a new none. No easy patch on those.

2,000 psi will shoot through the rubber.  Get another line.  With it leaking your engine is not going to run well.  Call local repair shops to find out who hoards the vw diesel stuff.  In a pinch, the early 80s Merz 300 series is the same length and ends and can be bent to fit.

I flowed a bit of bronze using a mapp torch on a pinhole and it's fine for years now.

As a temporary fix, a bit of solder might be fine.


Consider 2000psi... how many pinholes in a sq-in...?  100x100?  maybe more.... say it's 2000.
That's 1lb of pressure, if you are sealing the area of just the pinhole.

P.S. if the hose & clamp bit drip, that's still better than a pinhole misting fuel in the engine bay. (BTDT)

yeah lol, 2000 lbs per square inch, not per each individual measurable piece of the line.

I would think a rubber fuel injection line, rated for some pressure.. clamped real good right at the pinhole should work as an extreme temporary fix.

[homerj1]

I was thinking about the pressure in the injector return lines.

Although the surface area responses pin hole vs  an actual sa of I sq inch,  makes sense. I'll try that tomorrow like a bandaid
Just in case, I'm currently in Montreal, so if anyone had a suggestions for injector line sources in the city, it would be appreciated.

thanks

I have a few sets of lines.. but that doesn't help you right now..

I have a few sets of lines.. but that doesn't help you right now..

  Thanks anyway.

 I also have a set at home that I thought about bringing on the road trip

maybe jb weld wrapped in rubber hose?

[8v-of-fury]

I like the idea.. way better.

[libbydiesel]

Rubber fuel injection hose is rated @ 100 psi or so.  That means that a pinhole location that is 1/2000th of a sq-in may only be producing 1psi, but the rubber fuel injection hose is only rated to withstand 0.05psi / 1/2000th of an in^2...  It just as under-rated as if you tried to run rubber fuel injection hose the whole way.

yes hihdsight 20-20.. always in spare on road trips.. i borrowed themans tdi ones for my cali trip... got a set now too... but rember, tig, brass, solder... do not fill the pipe with it.. leak better then improper flow too...

i tried one of those brass couplers on my pin hole 1 first... fail...so triied tig...
