well one in particular, that screw that fits over the fuel lines for the fuel distributor and injectors - where is a place to buy they besides the dealership? I break them very easily because of those holes that let fuel flow through them is such a weak point. I fashioned one of my own, but it is not as good as the original.

if you're talking about Banjo bolts, you can get them off of any WV Rabbit or other CIS vehicle at a wrecker.

The banjo bolts are not that easy to break, and they are not supposed to be tightened up super tight. Are you having a problem with leaks?

Make sure that you replace the copper sealing rings that are supposed to be located on each side of the banjo bolt every time you unscrew one. Use a torque wrench with the correct rating (75%-85% of full range is the sweet spot on most torque wrenches), and you will stop breaking them.

I think the torque specification for most of the banjo bolts is 8 Nm, which is only 6 ft-lb. You'll need a small, precision torque wrench for this job (not the one you use for hub nut, etc!

)

...and use new copper washers.

What are the specs on the crush washers for the banjo bolts on the fuel distrib? The fuel/feed lines, as well as the injector bolts. Also, where do you get them? I found out quick that Auto Zone and Advance Auto aren't going to be much help.

For $75 I bought a whole 'drawer' or tray from a Wenzer truck. Bought it through one of the local import repair shops. Now I have a lifetime supply of all the sizes I need except the oil drain. Worth it to me, once and done.

Jolly good.

Fuel filter inlet: 14 mm (internal hole size of washer) , 14.5 ft-lb

Fuel filter outlet: 12 mm, 7 ft-lb (most probably)

Fuel pump outlet (3 washers required), 12 mm, 14.5 ft-lb

Fuel distributor inlet and return lines: (4), 12 mm, 7 ft-lb

Warm up regulator - upper connector: (2), 10 mm, 11 ft-lb

Warm up regulator - lower connector: (2), 8 mm, 7 ft-lb

Fuel dist. control line adapter: (1?), 12 mm (?), 11 ft-lb

Master pressure regulator plug (in fuel dist.): 10 mm(?), 9 - 11 ft-lb

All other fuel lines: (16?), 8 mm, 7 ft-lb
