I recently bought a larger IMS fuel tank for my WR250R to replace the piddly 7 litre OEM. I'll need to transfer the fuel pump which has 5 or 6 little bolts that require torquing to 4NM however the torque wrench I have is good for 8-60NM. Should I go out & buy a suitable wrench or just tighten them by 'feel'? Pretty sure going by feel is ok most of the time, but not for bolts attached to the fuel tank??
