Holiday Rambler in tank fuel pump quit. Cant find relay?

Are you sure it has a fuel pump in the tank? My Windsor doesn't have that, it
has an electric fuel lift pump mounted on the engine. I can hear it run for
a while when I turn the ignition on.

What sort of trouble are you having?

The Cummins engine has a 12V fuel lift pump on the engine ...didn’t find a pump in the tank on page 397.

Thanks Doug, but no fuel pump reference on page 322 I can see?
Do you see something im missing?

Also thanks to poster for Monaco group link!

Thanks for link to manual so have digital and hard copy now. No mention of auxiliary fuel pump in manual though.
Should be able to trace leads somewhere if lucky but many wires bundled together down the frame.

Thanks but not a GM. Its a pusher rear engine with a cummins diesel.
No hood. Small fuse box in rear lower battery cabinet and large fusebox in outside cabinet below drivers window.
Fuses and relays labeled but none labeled as fuel pump so kind of stumped.
Just learned Monaco/Holiday Rambler lost all pre 2011 records, diagrams and schematics in a fire darn it, so on my own it appears.

Join the group monacoers.org it is a group dedicated to all older Monaco products. There is a wealth of information on the group.

I do not know the chassis but I do know Workhorse. And GM in general.

On a workhorse front and center.. open the hood and if like me you are six foot. Directly in front (Center) is a black plastic box.. It's in there

On my 1992 Lumina the relays were on the top front rail (Radiator mount rail) passanger side. and it's one of them.

Generally relays are all "Grouped"

Never had a fuel pump relay fail
Did have the starter pilot relay fail (Yup right next door) fixed it (Actually fixed the relay... .Yup I know how to do that).

Horn relay is there too.
HEVAC blower.. Same spot.
