Hello Rv's
Im back again with my albatrose of an RV my 1992 Gulfstream Ultra limited. I can turn it over with the help of starting fluid but I think my issue lies with a bad fuel pump. I don't want to have to drop the tank to get to the fuel pump so I was going to cut a hole through the floor and make a trap door to gain access from the top. My question is regarding the plumbing do the Gulfstreams run their toilet pipe through a case of some sort??? I'm drilling holes in areas that should pop through the middle of the floor like in the hallway area but I'm running into some resistance.

Im at my wits end with this RV and have tried everything folks on here have suggested I do. I hope someone can give my some info.

thanks,
Mike

Why not just install a good external electric fuel pump and be done with it?

OK, I wasn't even aware that that was an option I don't believe anyone that replied has mentioned that. Are they running the same price as a regular one???

You can find decent ones for around $60 and up. Depending on where and how you mount them you will possibly hear it running/vibrating so location and installing some type of shock absorbing material is somewhat crucial. The last one I had to use was on a dodge one ton truck that seemed to always have vapor lock when towing. Dodge replaced the in tank pump for me twice before I just gave up and installed the external pump in line with the old one. I installed mine in the frame as close to the tank as possible.

In mine and many others the pump was OK it was the rubber hose between the pump and the fuel line that went away over the years. On mine you could see through the hose! A new outside pump won't be able to draw. This hose is up high in the tank. Here's mine.

That "thing" next to the pump is all that's left of the hose, now if you pump is bad and this hose is OK, you're in!

I my case the tank opening was to the rear of any plumbing and the pipes were in a protective metal "trough". The galvanized metal in the pic is this trough.

Well it looks like I'm going to have to drop the tank, because I can barely see the top of the tank to see the condition of the hose and it that's bad the external wont work. I cant get to the top of the tank through the floor SOOOOO I'm thinking tank drop. Now the tank on my RV has a drain plug it but I'm not even going to try and open it since it is so rusty. Is it possible to snake a hose down the fill pipe and siphon out the gas so the tank is somewhat manageable when I drop it???

If I am able to put in an external fuel pump where do I purchase one???? I've looked online but what is out there doesn't seem to pertain to my application, then again I have no idea what I'm looking for so it may be the right application and I just don't know it. Thanks to those that reply
