Welcome to the forum
- we have a good bunch here!
That's the way it is unfortunately. We have topped off our tank to the point where not another drop would go in dozens of times but you have to be patient. It is a little easier with the smaller car-type nozzles but it will still foam badly with those.
Our truck stop process (large pump nozzles):
- understand exactly how much fuel you need - we use VMSpc's "tank minder" gauge to keep up with mpg and fuel useage
- start the driver's side pump at a very low flow rate by use of the "fueling wedge" in the pump handle (pictures on our RV pages)
- start the passenger's side fuel pump on the first click
- go back to the driver's side pump and note when you are about 20 gallons from a full tank
- put away the satellite pump (the pump might have already clicked off on its own) and close the passenger's fuel fill
- when you are about 5 to 10 gallons away from full, pull out the wedge from the pump handle and hand modulate the flow until full
Sometimes when I'm lazy or the truck stop isn't busy, I'll just use the driver's side fill and fill slowly - slowly is about a tenth of a gallon a second or less. The last 10 or 15 gallons must go in *very* slowly.
BTW - my Freightliner fuel gauge reads about 10-15% low but it will indicate full so there is a gauge linearity problem. We have had our Info Center fuss at us several times because we are low on fuel - it will say 10% (or whatever) fuel left. When it says 10% fuel left (10 gallons) we really have about 20 gallons left. Of course I have no idea how much fuel in the tank is actually useable so filling up when it says 10% left is not actually a bad thing!
