I installed a new facet fuel pump for the onan. It seems to be working as I can feel it vibrating when cranking however no fuel coming out the line to the carb. I have a primer switch at the inside control panel that I can push to prime but when seperating the gas line from the fuel pump, no gas. What am I doing wrong? Thanks!

Always use 1/4 " new fuel line.
The fuel pick up is designed to ever empty the fuel tank. This way you will
have few gallon of fuel to drive on. Yes the other tank might be half full
or empty.

Scott,
As said, probably nothing...
Bendix Facet pumps do not like to do a dry lift at all.
Want a cheap, dirty, effective and nasty tasting test??
Plug any available hose on the pump discharge and suck on it. (If you have the stop valve, that will have to be on.) In a very short time, you should feel the change of fuel at the pump. If you don't, then work on that problem.
When you do get fuel into the pump, then try running the pump into a can. If there is a lot of air, then get some new 1/4 fuel line to replace the broken up rubber hose.
I would say welcome, but you came aboard almost two years ago. While you do seem to be working the forum, you have not put in a sigfile. Please do this so we can be of more help.
To do a signature, go to <Control Panel/Account Settings>. If you see a plus next to Preferences, click it. In <Preferences> you will see "Signature". Please fill in your name (we like to know who we are helping) a short about the coach - including major mods and geographic reference. The half that work the e-mail side did not get to see the Aledo, IL in the header and you may already have someone in striking range that be of assistance.
These people love to help. They are really the best reason to be here and own a GMC (TZE). As they remind me of the watermen that I know, I like to welcome new owners (even if I am a couple of years late) as one would be in that community. So,
May the Good Lord bless this coach and all those that set forth withing her.

Scott,
Good start, always do the diagnosis.
¿Question
No power at which coil?
If it is the ignition coil, then you are also not getting power to the fuel shut-off or the fuel pump.
Did you download the Onan books?
