Bought new skeeter fx 20 today, one tank took gas with ease other tank would not let in any gas in. Any ideas on what I could do?

I have a FX 21 that had the exact same issue. I took it back to the dealer. The mechanic said the fill hose that goes to the tank was severely kinked. He replaced it and gas goes in great now. Easy fix...

take it straight back..

Picked it up in Houston, didn't fill up till I got back to Dallas. Lines are not kinked in any way, seemed like a air lock.

Somebody a while back suggested taking an air chuck and blowing out the fuel vent to clear the lines, but you wouldn't expect a new boat to have obstruction line issues. Ohers have stated they have to turn the fuel nozzle upside down and it will fill fine, not sure what that does tho except direct the fuel in at a different angle.

My Skeeter is a lot older , but turning the nozzle up side down always works , every time , do not know why .

Here's some detail on that "obstruction" sometimes mentioned. If a boat's fuel tank vent line has a low point in its route from the fitting on the tank to the vent itself, sloshing fuel from a rough ride can get into the vent line when the tank is rather full. It can also get in there when the tank is filled very full and fuel "burps" into the line.

Once liquid fuel enters the line and gets trapped there (due to a low spot) that vent line is no longer efficient at letting air out of the tank as you add fuel to the tank. The air pressure inside the tank must climb high enough from added fuel to make some air burp past the flooded section of the vent hose. Such a condition can make it very difficult to fuel the tank. This isn't always what's happened, but it is sometimes.

It is always best to have an obvious and steady downhill flow from the air vent to the fitting on the tank. This will allow fuel that does get into the vent hose to readily run back into the tank, never blocking the vent. Some boats don't do this very well - there may be too much fuel vent hose with a droop in the line. I do know of tanks that were "cured" by removing excess length causing a low spot in the fuel vent line. I know of others where the vent line was rerouted to be at a steep angle upward from the tank fitting, thereby making in very difficult for fuel to get into the vent line.

Trapped fuel is why hitting it with compressed air in the reverse direction can possibly help. Be sure to remove the fuel filler cap when you do this - it will allow the compressed air to more easily push the fuel blocking the line back into the tank by not building up pressure in the tank as you try to blow out the vent line.

Skeeters are a little difficult in allowing gas to go in. I have some stations I avoid completely.
