Need help accessing Onan generator fuel pump
« on: August 06, 2017, 12:35:04 PM »
Working on a 2004 Holiday Rambler Admiral with an Onan Marquis Gold 5500 generator.  The generator will run smoothly for about 20 minutes, then starts sputtering, and eventually dies.  It will only restart after a cooldown period and I'm thinking it needs a new fuel pump.  The fuel pump should be readily accessible from underneath based on several YouTube videos, except for the fact that HR put a metal plate under the corners of the genset which blocks access to the fuel pump. 

I'm thinking I should take out the mounting bolts from underneath the generator and try to jack up the front of the generator enough to remove and replace the pump.  This will also involve unbolting the exhaust pipe but I don't see any other way to get to the fuel pump. 

Any other ideas?
