Bad fuel check valve?

I have a 2000 Holiday Rambler with Chevy Workhorse. We start the RV by turning on the ignition and then after a few seconds turn it off. Rinse repeat about 5 or 6 times and she starts right up. That is by far the easiest and best way to start it.

My question is if this is a bad check valve, is there just one fuel pump from the tank to the engine or am i looking at multiple possible locations for a bad valve?

Any help would be appreciated.

Thanks

Two questions:
1.) What does "Rinse repeat about 5 or 6 times" mean?
2.) Are you sure there is a check valve anywhere in your fuel system?

your check valve is installed in the fuel pump its self

in the old days it was in the fuel filter

you have 20 feet or more of fuel line so thats why you have to keep making the fuel pump come on

some where i for get but there is a bay pass to make the fuel pump stay on for priming its like key on for 150s or some thing like that

so when you are getting ready to pull out try to lave the key on and see if the pump comes back up and gets up to the pis you need


side note tho you could have a leak some where else like in a fuel injector

i would find where the leak down is befor getting new parts

I have the same problem and have been putting up with it for a long time. However, I only have to retry with the key 1-2 times before the engine starts.
My question is ....is there a check valve out there or a kit that can be installed on the fuel line to prevent the fuel backflow to the tank when the engine is shut off?
I can't see dropping the tank to replace the fuel pump at this time.
80,000 miles on the rig.
Thanks
