We have owned (in the family) this RV for 23 years runs great and now has 37K miles( yes we don't go out much) but when we do we have so much fun. Well Now the Fuel pump is out. I had a full take of gas, I pumped it out with a "Amazon" brand ext 12v pump with a 25ft hose to a 55Gal Drum. Took about 1 hr or more. i had lots of wind to get rid of the fumes. I was REALLY careful to not have anything go wrong. I also used 5G gas cans and starting putting alot of the gas in our cars. What I am asking is. what is the PN for the fuel Pump? Also i would the service/parts guide or diagram for this model. I am welling to pay for it. Just don't know where to get it. Does anyone have a link to it? I need to look up some of the fuel lines that goto the gas/tank/pump. when taking it down. one plastic line broke. so i need to find that part number. I have looked on the hose can can't find it. i can't wait looking at some of the upgrade you all have done to your RV. i did see the link, but will find sometime looking and getting some ideas. Thanks for your support.

It's a Chevy van.. that has a house on it.. go to your favorite online store and order basic automotive repair book for Chevy van of your yr..you will find tune up specs.. and wiring diagrams and troubleshooting steps for the chassis.. Haynes and Chilton sre my favorite.. any good auto parts store and they will have parts for around half price dealer charges and with lifetime warranty for most part.. and I believe they all come from same place.. just different label put on it.. but I am old.. just my opinion.. one just does not pass fuel pump factory every day.. so just a few places make all makes.. the dealer does not make parts..
Good luck and keep us posted

HOLY COW!!! taking the fuel pump off was EASY!!!! i bought the AC Delco MU1816. no one had the GM OEM part. So far the HARDEST PART was putting the new O-RING back on the new pump/tank. I guess newer model gas tanks have a metal RING around it and you can use GAS PUMP RING TOOL to force the pump to seat back into the tank. Well with a 2000 and older model. you have to use your hand and body weight. but what made it ALOT easier was, not only did i use LOTS of lube around the ring and gas pump. I also Boiled the ring in hot water to make it easer to compress.etc now i have to read how to splice a new wire hardness onto the new pump. its has a new type of 4 prong connection. maybe one day. when i am done. I will download all pics and make a slide show and me talking how i did this. so you all can see what i am talking about.
