dont worry about any of the hardware its more than fine although as noted use the fuel line for safety take notice of the small barbs on the clevice thats so the fuel line doesn't slip off. you might want to pull the AFS sensor out and seal the hole with monocote as the fuel from exaust will soak into the fuse were its exposed . I never used the AFS ever but didn't remove the sessor until I noticed the fuel soaking into the fuse weakening the balsa
