I want to change my aqua-hot fuel lines and to get the fiber glass fuel tank cover off it looks like I have to take the door seal lip
off. I have all the screws out and it looks like it is glued down. Am I missing something
Screws are also underneath the bottom frame.
Thanks, I will check it out tomorrow
If you are talking about the main fuel tank I don't have a aqua- hot on my coach yes it is glued and glued good I had to use a heat gun on the fibre glass cover and heat it up good to get the glued to let go and I got the cover off with out taking the door seal lip off after the covers are off you have to remove the seal lip to side the tank to get at the lines there are three bolts on each side you get to then from underneath
I just want to get the fiber glass cover out of the way and see it I can change the aqua-hot lines with the tank in place. The aqua-hot
quit once on the last trip and at night a few times I heard it almost quit, so I might have a fuel problem and as the fuel lines haven't been changed I'll start there. I don't want to get into anything major until spring as I want to ski every week.
On mine there was some double sided tape holding it in. The clearance is tight getting it out. You might be able to get it changed out without pulling the tank. Some have cut a hole in the floor right above.
Oldguy,
I had all my fuel lines replaced at MoT last summer. I do not know if all fuel tank pick-ups are identical but at least we have the same year and model coach, in fact they were only five units apart on the assembly line. The pick-ups were in two clusters on the starboard side. Unfortunately I did not specifically identify which went to the main engine, generator or Aqua Hot. From the below pictures the pick-ups toward the center of the tank appear much larger than the others so must be for the main engine. Therefore, the ones closer to the street side are likely the Aqua Hot, generator and vent line. The white strips you see on the end of the tank are very tenacious double sticky tape which make removing the fiberglass panel very difficult even after all screws have been removed.
If the Aqua Hot fuel lines are close enough to the edge it may be possible to replace them without sliding the tank out a couple of feet as the mechanics at MoT did.
Good luck,
Richard
The fiber glass cover is siliconed in place. It just looked like it wouldn't clear the lip of the door seal. I had to stop working on it
as it started to rain on Thursday afternoon and has been raining since. I hope it stops this afternoon.
Got the fiber glass cover off and waiting until my son gets here to help me sort out which hoses are for the Agua-hot.
They are changed.
Richard looking at your pictures I see only 3 other fittings after the aqua-hot fittings. Does the generator have no return line. I think
I will be able to change the other lines without removing the tank.
What brand and size or sizes of fuel line are being used.
The Aqua-hot lines are 1/4 and the other ones are bigger, maybe 3/8 and they may be different sizes. I didn't pay too much
attention as I wasn't going to do them this weekend. Someone else may have the answer.
Both the main engine and the generator (any Diesel engine) will have both supply and return lines. I don't believe that Aqua Hot has a return line, only a supply line.
Edit: I stand corrected, The Aqua Hot does indeed have a return fuel line as well as its supply line.
Thanks Craneman for enlightening me.

It has a return line.

My configuration is different but I thought there should be one more fitting and I see there could be one in the middle of the
tank somewhere. Thanks for the pictures.
The supply for the engine is in the middle of the tank along with the vent.
As the engine supply is in the middle of the tank I don't have much choice, I will have to pull the tank when I change the engine
fuel lines. I think the vent line is on the right side of the tank as I was only missing one fitting. I wondered why all the fittings
weren't together then I realized going around corners the pickup will have more chance of staying in the fuel when the tank is low.
Are you saying that changing the AH fuel lines were done without moving the fuel tank? If so, how hard was the job. I'm looking at doing my fuel lines when the weather thaws.

I have the opposite question.. thinking of removing mine and adding a longer pickup tube for Genny.. I understand the Cons involved
There are 5 fittings on the side of the tank. 2 supplies for gen and AH, 3 returns for engine, gen. and AH. 2 fittings in the center, engine supply and vent.
