Where is the fuel pump relay or fuse on ford 7.5 rv chassis

Maybe you can reed this:
Get in the van and roll all the windows, turn off radio and a/c and kids. Basically you want to create a quiet environment just for a second or two. Now engage the key as if to start the motor but don't turn the key all the way to start the motor, just before this point. You should now hear a "buzz" or "wind" behind you towards the back of the van, just for a few seconds. This is the fuel pump engaging and pumping fuel. If you don't hear this wind then try it again. It has nothing to do with pumping the gas pedal. It is an automatic item that turns on then off quickly because it thinks it has shot enough fuel from the tank all the way to the motor to start up. If no wind then I'd check and even replace the fuel pump relay which is right above the battery towards the back of it. Actually you will see 2 relays there and they are identical. You could always just switch them to see if the relay was bad. The other relay does something obvious on the van that I forgot but it will be apparent once you disconnect both as to what the other controls. If the fuel pump relay now works in the other slot then the relay is good BUT your fuel pump is most likely bad. This stinks because now you have to lower your gas tank to replace the pump which costs $150 or so. It is easy to do but takes a good 3-4 hours and an almost empty fuel tank is preferred before you begin because the tank is already heavy enough empty. The only special tool needed is a fuel line disconnect tool which is a $6 tool at any auto store. If you hear the sound then the relay is fine. You might want to check to see if your fuel filter is clogged. Again easy to do but messy. Use that same fuel line tool and wiggle it between the end of the fuel filter (right under the van driver's side) and the line. It won't fit that well but just keep wiggling. Now press the line towards the tool and pull line back and it should pop off. Have a rag handy because fuel will drain from the loose end of the hose that goes to the motor. Now get in the van and quickly engage the key again. You should have shot a few ounces of gas onto the ground (I say ground because you should do this outside in a well ventilated area and NOT in your garage). This means your filter is fine. Next I'd check your spark.
