3.3ft-lb on a bolt.. without a torque wrench?

I'd say it's roughly equivalent to 3.3 lbs acting on a foot long wrench ;). Or 6.6 lbs on a 6 inch wrench, etc etc. How long is your spanner/wrench? Calculate how much force you need on the end of your wrench to be equivalent to 3.3 ftlb then weigh an appropriate thing on your kitchen scales and apply it to the end of said wrench if you can get it horizontal (or do slightly harder maths if you cant). Simples :)
 
Little inch-lb wrench as said.

FWIW, BMW M52 rocker cover bolts are similarly specced. Ignore it at your peril, they snap very very very easily.
 
It's the fuel pump assembly on the Subaru. I previously snapped one of the 8 on it causing the fuel tank to not be pressurised. I have just made an attempt at using chemical metal to replace the bolt.. but it didn't hold even turning the nut with my hand.

O well I've replaced the fuel pump assembly seal anyway so I'll just have to see how it goes for now.
 
Oh the tank bolt, haha that's fun when they snap off.
Drill the old one out/off, put a longer one through, stick the nut on and hold onto the long threaded bit left with double nuts so that you can still tighten down the single nut..

Extra fiddly holding onto it though while trying to lower the fuel pump assembly back onto the studs. Good luck. You'll drop the bolt about ten times before managing it... or giving up :D


Edit **

Oh and don't be so ham fisted doing them up next time.. :p

1/4" drive ratchet, 8mm socket, finger tips and tweak gently. No need for a torque wrench!!

Scooby, I *think* I have a torque wrench that can go that low if you want to borrow it? Will go out to the garage and check.
 
Thanks Concrete, I seem to have got away with it for now though. The fuel tank seems pressurised. The new gasket seems to have done the trick.

If it stops pressurising again I'll give you a shout... Once I get the courage to drill the tank that is :D
