RV12is - F12127B/C

I am building the RV12is. I'm experiencing difficulties tightening the F12127B/C fuel line fittings at the firewall due to limited space with the rudder assembly. Any suggestions as it relates to tools and/or methods would be appreciated.

I ended up using a crow foot wrench. I tightened the fitting by hand then used the wrench and tighten it the additional 1/4 turn with the wrench in my hand. Definitely couldn?t get the breaker bar or ratchet in there either.

i cant remember exactly what i did.. but there was a standard wrench, a crowsfoot (which you'll probably need later for connecting the fuel tank anyway), a lot of foul language and patience involved.

as difficult as this task is, do it right.. because in a few sections ahead, there will be even more stuff occupying that center channel..

Both great recommendations. Thank you

Flare Nut Crowfoot Wrench is excellent for tightening soft tubing connections...
