Fuel line connection to FD......torque?

You cannot really put a 'torque' figure on something like that, when ever I replace steel lines I usally tighten them as tight as I can using common sence and the correct size tools also, eg..If I had to tighten up a brake line I would use a small 1/4" spanner and tighten it as tight as I could with the minimal leverage that I have off that spanner, I would not use a 12" shifter to do the job for instance, same goes with a larger diameter hydraulic steel pipe on a loader, it would use common sense if I had to tighten 3/4" pipe, I would only use a 7/8" spanner and not an 18" shifter.

It's good practice to also use two spanners when tightening up steel lines so you do not twist the lines when you tension it.

It's good to hear your replacing the copper gaskets also and I hope your major went well on your Boxer

 

I believe the "spec" for the top banjo bolts on the K/KE FDs, where you can actually use a torque wrench, is something like 11 ft-lb, but I use ~13 ft-lb (and do support the line/fitting from twisting during the tightening)-- if going by just feel, you'd actually probably go higher. (Would be interested in your opinion at the 11 ft-lb level.)

Pap's comments about common sense and the length of the wrench for the size are about all that you can do. They give a bunch of quasi-useless torque specs for various fuel fittings where the only possible tool option is an (or a pair of) open end wrench(es) so you're stuck with doing a "feel the force" x "length of wrench" guesstimate. If it leaks -- go tighter

 

there is a torque value,
from the WSM....
the fuel pipings to the FD and cold start, 8X1 thread = 0.85 daN.m
Union from FD to WUR, 8X1 thread = 1.25 daN.m

I think you are misreading that table -- injector line to FD = M10x1 (at least on the six position Boxer and TR FD) = 1.5 daN-m = 11 ft-lb

 

the toque values are in deka newton meters, most converters do not have that value. this one does, http://www.convertit.com/Go/InfoVenezuela/Measurement/Converter.ASP

the 0.85 daNm is 6 ft*lbf
1.25 = 9
1.5 = 11

etc..

 

probably Steve, considering it's a Ferrari torque value chart on a Bosch part they may have it off too. my Bosch service manual for the CIS doesn't list a tq value for the fuel fittings but is very clear on an accurate value for the screws holding down the FD body, 2.4~2.8 ft*lbf.
