1940 p10 fuel tank same as 42-48 p15?

[Greg F]

Think I need a new tank, as I can not seem to get gas to the fuel pump.  Runs great from a gas can, but nothing when I connect the fuel line to tank.  Called Tanks inc, they have tanks for 38-39 and 41-48, but nothing for 40.  Is the 40 tank that different from 41-48?  Anyone used one of their 41-48 tanks in a 40,  or should I just have the current tank cleaned, to see if that is my problem.

 

Thanks Greg

Have you inspected your fuel line from the tank to the pump? A very  small pin hole is enough to stop the fuel pump from pumping.

Looking, but no luck so far.  Frustrating.  Thanks shel, looks like they are the same.  Have a tanks inc in the 47 and has worked great, may try.

 

Thanks as always for the help...Greg

On the tank connection, or in it, is a small barrel shaped ferrule which seals the space between the fuel line and the dip tube inside the tank.  This item is really easy to lose and its absence will allow air to leak from inside the tank and it the tank is over half full fuel will escape around the line.

 

As for later tanks fitting a 40, I see no reason why they should not.  The chassis frame is different from 42 onward but the bodies, at least in this area are the same.
