Need Generator fuel hose recomendations

What hose is the best for the pressure and return lines?  Just curious with the changes to fuel the last few years if one was better than others.

I don't think I was clear on the original post.  I am looking for the small return hose and the pressure hose going to the pump from the line coming from the tank.

Jerry,
On our coach generator this is what we have replaced ours with  Oil Resistant Textile Covered Fuel Hose | Gates Corporation  Gates recommended it for both the suction and return.  Have not had any problems with air leaks or drips.  We have the Isuzu 3ld1 and have changed out the lines between the injectors with this also as it will handle the heated fuel.  Now this stuff isn't cheap for the size but......

There are a few threads that talk about this. 

The factory seems to be using a Parker diesel rated plastic tube similar to PEX tubing.  It is rather expensive unless you are buying full reel quantities of it (much more than you would ever use on one coach) so myself and some other people have used Trident 365 fuel hose which was reasonably priced and could be bought in the quantities needed.

Gates RLA low pressure hose for bio diesel replaced both supply and return.  Gates will not recommend for barbed fitting, so had their Gates steel Mega Crimp on fitting for tank (brass was not available).  I used hose clamp on other end at generator.  Had to pull tank to get to center of tank where gen supply was.  Bled hose, engine started right up.  As hose did bind a couple times, for me not as simple to replace as others have said. 
I placed a four inch long brass pipe, threaded on both ends, to combine the new and old hose to pull thru starting at the the tank after cutting hose there.  Like an old Chinese finger toy, the hose gripped tighter on the threads as hose was pulled.  Again, important to block chassis for safety as you are working right next to air lines if you go under chassis.
 RLA Return Line & Low Pressure Hose | Gates Corporation  This is what I used for both supply and return.  You can check price at a couple different local replacement hydraulic hose shops.  I used 17 feet of each which was exactly right, as one just made it.  I would use 18 feet if I did it over to be safe for return, 17 for supply.  Supply is in the center of tank, return is on the outside, 17 feet just made it for the return hose.
