* If you have the setup for SDS fuel pumps, consider not running the hose from the fuel valve to the pumps in a straight line. The hose is very short and stiff and has no way to shrink / stretch if there is no bend in it. It also gives you a bit more freedom concerning how far to screw the fitting into the pump assembly. The milled distribution manifold may not allow you to add another full turn.<br>[[File:2023-09-04 14-32-38.jpg|467x467px]] | * If you have the setup for SDS fuel pumps, consider not running the hose from the fuel valve to the pumps in a straight line.

* 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 stretched over the fitting after putting them in boiling water, suitable is ID 0.5 (1/2), OD .594 (19/32) ([https://www.amazon.com/dp/B08XQ4WTKF at Amazon]). 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. Try to push the step drill bit away from the screw hole as you enlarge the opening. This minimizes the rubber grommet interference with the washer / nut when | * 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). 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. | * For SDS installations, a second hole for an additional 90 degree fitting needs to be drilled into the side skin with a step drill.
