Need to know the specific model. Like most RV manufacturers, Allegro does not manufacture the chassis or the drivetrains for their RVs.
Check under the driver side on the chasis.
3208 cat in 1988 elite motorhome
On the frame rail about even w/ the trans. bell housing on the outside of the fuel filter bracket.
Not enough info to answer that question.
On the in-tank fuel pump, or pumps if you have two tanks.
On my 1989 E350 motorhome, I had a weak fuel pump near the fuel filter. I replaced that and the problem went away. The pump in the tank was fine.
Usually on the dashboard. Are you sure it has a "Fuel" aux. switch.
on the frame rail near the transmission special tools needed.....only a couple of bucks at the parts place. ford wants $100. There might be a second one next to the front fuel pump underneath the drivers seat bolted to the frame.
It runs underneath the the motorhome inside the frame towards the rear.
you have to remove the tank, the pump is in the tank
passenger side below dash
My motorhome is a 2004 Itasca on a workhorse P32 chassis. The fuel pump is inside the fuel tank. I'm in the process of changing it right now.
