Title: learning curve...td fuel lines
Post by: vwroadkill on March 17, 2014, 06:31:54 am

so where was it written that I had to use TD lines. cause I missed that point.. I swapped out my worn out 1.6 for a brand new 1.6td.. block thinking.. {I know! don't think}. after installing rebuilt pump. old lines would work,,, NOT. LDA hits #1 fuel line. and after looking at my kids car.. they are made different.
so here is the question. are the lines a specific length? is the diameter,
I can make the line. I just want to be sure.
can I alter what VW has made... I mean the direction they lay the lines out
just cant believe that this would stop me from running correctly. plus I don't want to break anything
Idea's? inputs? thoughts?

Buy a line of mk1 autohaus on ebay. The TD and NA lines are different on the 1 and 2 IIRC. They are all specific length and take a high pressure *more than brake line* requirement.

same seller does single lines.

I wouldn't try to make your own, they need to handle several hundred bar

I would not mix NA and TD lines.

You can time the pump 1 tooth off and that should give you enough clearance to get the lines one.

Usually if you bend them they will crack within a few hundred or thousand miles.

mk1 autohaus does sell the lines separately. weird thing is if you search by jetta they show you the cylinder 2 TD line and the others NA, search by rabbit and it shows you the cylinder 1 TD line and the others NA.

probably an oversight.

There's a guy selling a used set on ebay but my analysis of his pictures is that he doesn't have the TD version for cylinder 2.

It would appear that the  n/a and TD lines are the same length, at least up until the intercooled stuff '88+ which may be different length.
 Then AAZ definitely wrong shape, and possibly different length.

As already stated, shift pump[and pulley] to a more upright position to use n/a #1, and #2 on a TD pump...

well I got couple choices... one make my own..no worries theman aircraft grade lines for a hydro system, ahem you know the kind from a large prop driven 4 engine gray airplane.
two get some used one's... thank you burn..
three order new set... NOT
I did the one tooth off and it works but its cheating, my OCD wont let me do it for long.
thanks for the input

yeah i would rather have the right lines.

I have time to wait for stuff to get here since i still haven't extracted my engine. it was going to be this past weekend but then the constabulary pointed out to me that the Mk5's taxes were in arrears by more than 90 days.

Probably because I was pretty sure it would not pass a thorough emissions inspection. Fixed that instead.

So now i am aiming for this weekend to get the engine out, separated from trans, and onto a stand.

The problem with making your own, even if you have the ability to manufacture them out of the correct type of material, is that they need to be of equal length. This is absolutely critical, or the timing for specific cylinders will be off from the rest. The silly straw bends in the #2 turbo line serve an actual purpose. Of course, if you had a sample or something to work with you might come out with a correct line with the right bends in it but then you might as well just install it, right? They are rare but not unobtainable, at least not yet, fortunately.

Not sure if this helps at all but here is a link to my recent purchase for an AAZ 1.9.

Yeah, expensive but cheaper than a tow truck from 600 miles out!
