Injector return line torque value? (1 Viewer)

[300D]

Hi. Reassembling the fuel system on my 2.2 liter L engine. The manual has me torquing the injector ‘holders’ to 50 ft/lbs, and the fuel pipes to the injector holders from the pump at 20 ft/lbs. But it weirdly skips the nut that holds down the return line thingie. Any suggestions on a torque value? I have them currently at 25ft/lbs.

These are very similar injectors and return pipe to the 2H engine.. the spec for that engine from the FSM is 36ft/lbs so I think you're in the ballpark. If they dont leak when started you'll be fine. Keep a close eye on the return line if you do torque them further and you if you havent already I would use copper antiseize under them as upon removal the injector return line is prone to want to turn with the nut which can be quite problematic.

Thanks. Super helpful. I going down to the truck today to hopefully wrap up and get her back on the road.

if they do leak, loosen them up while its running, give the washer a spin and tighten it back.. I had a helluva time getting mine sealed at first on my 2.4

I've always had to overtorque mine to have them not leak.... That's pretty much my metric now: If they don't leak it's good enough.

Thanks for the tips. I was about to fire her up just now, but realized the ground strap was not connected. Connected to battery, not to ground. Now I can't remember how it was setup. I will post a new thread. I will update when I get her started.

Stuck with the 25ft/lbs. on the return collar hold downs. got it all back together, and it is running beautifully with nary a drip anywhere. (Knock on wood) Thanks for the tips.
