  • Fuel line on a 621
  • I purchased a fuel line for my 63 621 USAF Tug, just in hand looking at it I have no clue how this thing is going to fit. If you lay it on a floor it's completely flat. The sending unit and carb are on two completely different angle to each other. It came from Steiner, there are no instructions other than the muffler needs to be removed. Can anyone offer a little insite, please. I am going to call them in the morning.

  • If you look at the gas line on my 640 you will see it snakes up inbetween the intake/exhaust manifold pipes. I don't particularly care for fords design on this one. I usually run my lines around the front of the engine. Your sediment bowl might have been turned around so that the gas line hookup would be on the outside instead of the inside.

  • ok, i dont have the sediment bowl on my carb like that. it currently has a "banjo"bolt in there.the fuel shut off in the tank (Stiener #ABC127) has a filter but no sediment bowl like my NAA. The fuel line i got is Steiner #FDS1544. Would you happen to know the part number of the sediment bowl i need? and are the two i have so far correct?
    Do you have an email i can maybe send a few pictures to? i have no luck getting on this forum.

  • Doug,

    One word of caution. The bolt which holds the sediment bulb in place is a hollow bolt and has a hole through the side which must line up with the passage inside the sediment bulb. The sediment bulbs are manufactured with the that passage either to the left or right of center. You must match the bolt to the bulb assembly. You can spot the difference by the fact the fuel line comes down either to the left or right of center also. Hope this is clear! My 860 was one way, my brother's 861 the opposite.

    Good Luck,
