Bounder Fuel Pump Relay

Hello all. Have a 1993 Fleetwood Bounder with GM 454 TBI engine & had a sudden loss of fuel at the injectors. My question is, can anybody tell me where the fuel pump relay is located? I want to eliminate all other possibilities before getting into the nightmare of dropping the tank.
Speaking of that, any tips on how to get the fuel out?

Sorry I can't give exact info on relay location, for your coach.
Can you disconnect wiring in the tank area to check for power there?
Be aware that there may be a shut down cycle on the pump , either oil pressure or RPM related , not sure which on your unit , but the pump may only be powered for 10>15 seconds, after key is turned on, if the engine doesn't start, or have oil pressure.

Note that the pump may be brought back to life , by bumping the center of the bottom of the tank while someone is cranking the engine. Big rubber mallet is what I used to use , to get vehicles into the shop, for pump replacement.

Fuel pump

Wish I would have known about the trick of bumping the tank with a rubber mallet. Years ago, on my old Class A on the P30 chassis and 454 engine, my fuel pump decided to die just as I was turning into an intersection pretty much blocking traffic on both roads. Called AAA and they sent a tow truck that was able to pull it off the road. Luckily, I was only about 2 miles from home, on my way to gas it up for a trip. I bought a cheap aftermarket electric fuel pump at Autozone and some hose and clamps. Jury rigged the pump in place of the fuel filter located on the frame rail and was able to start it amd make it home. I used that pump to get the remaining fuel out of the tank. Not a fun job replacing the in-tank pump, but at least I was able to do it in my driveway and not on the side of the road LOL.

Not sure what chassis you have, but on the P3 the fuel pump relay on the P-30 chassis will be located near the firewall, could be under the dog house mounted on the side firewall, would be underneath your right foot,

these relays could be a few positions YMMV

How many miles on your rig??

SKIP426, thanks, already did the banging trick, actually a mechanic tried it on the side of the road.
CJ7635, thanks for the info, it is a P-30 I think. Will be doing some trouble shooting when the rain stops.
