Fuel filler back pressure

[gbvona]

1970 NADA 3500S

The fuel filler has a conical insert into which the filler nozzle fits. The insert ultimately bends towards the tank and has a corrugated hose attached to it (about a foot long) that takes the fuel past the outer rubber casing joints and into the tank.

The problem with this is that with the modern fuel pumps used in the US (at least) if you put the nozzle more than a couple of inches into the filler, the flow of fuel generates enough backpressure to shut the pump off. The only way to get fuel into the tank is to hold the nozzle near the top, which runs the risk of (considerable) spillage.

Anyone run into this problem? Suggestions?

Hold the nozzle upright with the trigger over the bootlid and the handle vertical, with the nozzle in as far as possible so there's one continuous curve through the fuel hose, nozzle and filler neck, if the trigger is over the wing it's a sharp "S" which makes it back up and cut out the pump.
