* The fuel line(s) under the seats are held by F-1084A/F-1084B. Normally the metal lines are protected by plastic bushings with 0.375 ID / 0.5 OD. For the premade hoses, one can use rubber grommets forced over the fitting with a bit of heat, e.g. ID 0.5 (1/2), OD .594 (19/32). This requires enlarging the two forward F-1084 holes to 19/32 (two for SDS installations). Make sure the F-1084B top part is on in the right orientation as it is not symmetrical. | * The fuel line(s) under the seats are held by F-1084A/F-1084B.

* For the large existing fuel exit hole (which usually holds a rubber grommet for the metal line to come out), use the TCW machined washer / fitting set. Use the machined washer half on the inside and the plain washer on the outside. The outside washer needs to be trimmed on the lower side to not interfere with F-1099G (4 hole wing root fairing support). | * For the large existing fuel exit hole (which usually holds a rubber grommet for the metal line to come out), use the TCW machined washer / fitting set.

* For SDS installations, a second hole for an additional 90 degree fitting needs to be drilled into the side skin with a step drill. The location is specified in the premade fuel line manual (1 1/4 rear of rivet line, 1 1/2 inches up from side skin straight lower edge. The diameter is smaller than the existing hole, just large enough to hold the #6 fitting (9/16). | * For SDS installations, a second hole for an additional 90 degree fitting needs to be drilled into the side skin with a step drill. The location is specified in the premade fuel line manual (1 1/4 rear of rivet line, 1 1/2 inches up from side skin straight lower edge. The diameter is smaller than the existing hole, just large enough to hold the #6 fitting (9/16). This fitting needs a washer to increase the thickness. Consider using aluminum "AN SPACER, 6D" from Vans (needs to be trimmed a bit because there is a bend close-by. | ||
* Consider fluting and riveting F-1099G to the side skin before installing the fuel fittings and under-seat hoses as the full rivets will be hard to buck with the fuel system installed. | * Consider fluting and riveting F-1099G to the side skin before installing the fuel fittings and under-seat hoses as the full rivets will be hard to buck with the fuel system installed. | ||
