Fuel line aging out

We own a 2003 gv320 I don't see any obvious wear on the fuel lines going to the fuel tank. I was wondering with other Foretravel owners if and when they replace the fuel Lines? It's a big job and I would like to wait as long as possible.
Thank You

From following this on the forum, it seems to be a problem with 2001 and older coaches.  My 2002 (build Aug of 2001) does not show any problems with over 200K on the chassis.

You check for cracking in the lines where they join connectors and the hose is stretched over the connector.  You can check both the engine and generator lines.

Same observation.  In the 20+ years I've followed the forum and its predecessor Yahoo Group, I've only read of one 2002/2003 coach that needed fuel lines, and that was within the last year.  There was some discussion awhile back regarding a material change in the fuel lines starting in 2002. 

2001 and earlier are another story.  A couple of years ago you could follow the fuel line changeouts almost like clockwork for each model year.

My engine will lose prime over night LOL. I gathered all the materials to replace fuel lines with the plastic air-hose style tubing.

Our one generator fuel line is the only one that has shown any type of failure in our '93. Any problems with starting may come from air getting in at the fuel filters, hand or electric primer pump, fuel pump, end of fuel line where it goes through the fittings. Our frame mounted hand primer pump leaked air and the gasket between the primary fuel filter and the bottom sight glass also had an air leak. Isolating the different parts and using a mityvac can find the problem.

After sitting for any long period, I use the primer pump to build pressure and push any air back to the fuel tank. Makes starting almost an instant thing.

If you cover any lines or cables with vinyl expandable tubing, it make the job much easier and can be done by one person. Rodents don't like the stuff either.
