Frequently asked questions

How do I run fuel line through a firewall?
Use a bulkhead fitting. Drill a clean hole, push the fitting through and lock it with the jam nut, then connect a hose end on each side. A 90 degree bulkhead keeps the line tight to the panel.

Do AN fittings need thread tape or sealant?
No. The seal is made on the 37 degree flare, not the thread, so keep tape and sealant off the AN side. Only the NPT (tapered pipe) end of an adapter needs sealant.

How tight should AN fittings be?
Snug them up by hand, then about a quarter turn with a proper AN spanner. Aluminium fittings do not need much. Over-tightening can crack the flare.
