I read here once about someone smearing the hose with vasoline then wrestling it on. I wouldn't go that route. Others say they've trimmed the length in order to get it on. I figure it was designed with a specific length for a reason.

That small $2 hose will require removal of the H2O pump in order to change it out. The archives are full of how-to's on the M103 water pump.

Good luck.
