5ktq metric fuel line fittings

[Kurt Deschler]

To follow up, the 5/16 lined spliced up great to the 8mm lines. The 
installation looks OEM and took around 3 hrs. Cost was around $40, mostly 
in fittings. The NAPA guy told me that the cost of fittings had basically 
doubled in the last few years due to an increase in raw material cost.

Here are some tips from the install:

The lines are 72" long. The longest single tube that I could find was 60". 
I cut a 30" in half for the front side and coupled these to the 60" lines. 
the cut side attaches with compression fittings to the original 14mm 
metric ends at the front. The original ends should be cut just in front of 
the last hanger. They do not need to be disconnected but must be sanded 
smooth for the compression fittings. Get the back side bent, attached, and 
hung. Installing the hard plastic line to the fuel pressure accumulator on 
the new nipple is a nightmare. Best bet is to pull down the accumulator 
and remove the line. I ended up using a cigarette lighter after wrecking 
half of the line with a heat gun. Only heat the very end of line and only 
enough to get it on the fitting with significant force. Finally, tighten 
all of the fittings one you are sure it all lines up.
