I would look at the FAQ on the website before installing. Mine was installed incorrectly and is an absolute b*tch to fill up.

Why is it so hard to fill my fuel tank after the tray was fitted
The filler of our LongRanger tank is in the same location as the OEM tank, the original steel filler neck on the vehicle does not lend itself very well to being lowered. Whether the standard fuel tank or a LongRanger is installed.
Unfortunately some tray manufacturers modify the fill neck to mount under the tie rail which is generally to low for the fuel to flow from the bowser to the tank or they rotate the fill neck and have a low point in the fast fill breather causing an air lock.
A well designed tray will have the fill neck mounted high and the fast fill breather with a gradual rise from the tank, below is a graphic for explanation.
During the fitting of a new tank it is important for the fast fill breather to have a gradual rise from the tank to the filler. If this is not done an air lock can form where fuel will accumulate stopping the air from escaping as you fill the tank, see picture below for do’s and dont’s of a filler neck install.
