Fuel Pump Cap Nut Torque
Can’t find it in my Bentley, or the PP How-To.
Is there a torque spec for the fuel pump cap nut, or just tighten til you feel the washers crush? |

14 seems excessive to me for what it does. Tighten it enough that it doesn't leak, plus a little bit more. Don't squish the crush washer.

I posted the torque items but I do what PeteKZ does, I used new copper washers on my new pump and tightened them down by feel, snug with an extra small oomph. No Issues. Ive also read 12 lbs but that seems high also for that cap nut on the banjo bolt.
