Brief Description: Fuel Line Bending - Valve to Filter
|
|
Bending the fuel line for the selector to filter has been, well, challenging. I probably have a dozen attempts or more... consumed the entire 8 feet of 3/8 tube from Vans, and ordered more from A-S. The outside diameter of the A-S tube seems to be a smidge bigger than from Vans, but workable. Below are pics of numerous abends - abnormal bends...
The reason for the difficulty, the fuel valve is ~ 4 " virtually, above, and slightly forward of the fuel filter, and at about 100 degrees differential. The Fuel Valve being relatively vertical, and the fuel filter being relatively horizontlle.
So, the only way I could make it work is: Fuel line departs the fuel value at 90 degree turn away from the fuel filter, (with enough drop to allow for the flaring at connector), then immediately turns back to the right, at 180 degrees, at the same time decending the ~ 4 " down to the fuel filter. Next the line runs ~ 2", then turns another 90 degree right, to eventually mate to the fuel filter.
