Toyota Repair: how to replace fuel hose from gas cap to tank, mini motorhome, fuel proof

Question
I have a mini motorhome built on a 1988 toyota 1 ton chassis.  Just had the fuel pump replaced but was told the hose from the gas cap to the tank itself needs to be replaced as it's cracked and in fact leaked when I got to the gas station to fill up.  

I'd like to try to tackle myself if it's possible.  

looking for instructions/pictures/video.

Thanks!!

Answer
As you probably know the hose is different than the factory part so you will have to get some fuel proof hose from an autoparts store and cut it to the correct length, there is really nothing in the way between the fuel filler neck and the fuel tank pipr so it should be fairly straighforward, take the old hose with you to an autoparts stores and they can probavly match it up for you.
