I would like a single hose that is at least 3 feet long - 4' would be good with the proper fitting for the pump (1/2" FPT/FIP with the rubber compression piece I believe).
This 
SHURflo Pump Silencer Kit consists of two 3' long 1/2" hoses with factory installed 1/2" FPT fittings that will connect to the pump fittings perfectly ... if 3' isn't sufficient just barrel the two lengths together with the included M > M fittings.  Valterra makes a similar kit and since either would suit your purpose just fine I'm unclear as to why you'd prefer to not use them. :h
An alternative is to buy a 
4' Valterra potable water hose and convert the 3/4" GH fittings to 1/2" FPT using this 
SHURflo GH > NPT Fitting, the only downside is you may have to change the sex of the one GH end.
