Hey all. I read in a few places that the fresh water tank fill is in the LPG locker, mine doesn't have that. I am guessing the city water connection is also want fills the tank. Problem is, when I'm hooked up, it's not filling the tank, and poor pump doesn't stop when it's switched on!
I have looked all over this thing for any other connection, or a valve to divert the water to the fill the tank, and I'm coming up with nothing. You folks have any suggestions to what I'm missing??

What year is your coach and model?
not a hard thing once you have the right parts.

As Jim K. stated, We need the year, model and length (23 or 26) of the coach. There were several different set ups for the fresh water tank.

If your 74 coach is still as original the city water inlet does not fill the tank.
The tank fill is gravity through a fill port in the propane compartment. This fill was equipped with a locking cap.

Kelly,
If your coach has a potable fill valve, someone (like me) added it. It is a suggested mod.
If you want to know how to do it, just ask.
As said, the potable tank fill was in the propane locker of all 73&4 Gemini fit coaches. It is most notable for its inconvenience and poor performance.
I suggest that if you can't locate it in the propane locker you should open the starboard settee and see if it is still attached to the tank. It will be hard to miss as it is about 3" in diameter and has an ell right out of the tank. (I guess they did that to keep people from filling the tank too fast.)
It would be good if you included the length, model and year of your coach as this can make differences. A real name there would be good too.
We are glad you are here in any case.

Alright fellas, '74 26'. In the LPG locker, there is a tube that runs from the top, around the tank, and back to the pump. I'll post a picture of the tank pump under the bed...

That is where the water tank fill is on my '75 26 footer and where it was on my friend, Dan Gregg's '74. It should have a large cap on that tube that you can run water into with a small hose (Dan's '74) or a hose connector to connect a water hose to (my'75).
You can kind of see it in the upper corner of this photo:

That fill hose is routed outward and connects back down to the drain valve and to the pump...
You can see where it enters the LPG locker area, like it used to...
Bottom left margin it enters the locker, only to reappear back in the photo out of view under the pump. I've depressed the Schrader on the accumulator in hopes of purging air, but I got nothing. Next step is splicing in a female hose connector and filling it that way...
Also, strangely enough, the city fill port has mild back pressure. I think there is a check valve somewhere causing me frustration. Also, the hot water heater is caked in foam, so it's dig the foam out to change the element, or run 'pane...

Word of caution here. If you do use a hose connection to city water be sure that the vent is capable of venting the tank at or above the fill rate. Otherwise you run the risk of exploding the water tank due to excessive pressure.

Thanks for the heads up, it does have a vent tube. So if I bleed the city fill inlet, and open the faucets, the water will bleed out. Then, if I turn the pump on, I do get a trickle, but the pump still doesn't prime. Arrgh!

Here We go Kelly,
The pictures are a lot of help.
Just in case you haven't figured this out, your coach's potable system has been severely molested.
Where the hubless joint (the stainless and rubber thing) is clamped is where the atmospheric fill used to be. That is what we were all telling you should have been in the propane locker.
How the PO expected you to fill the tank, I can only guess.
But here is the guess.....
Put city water on at the fitting that I hope is still where it belongs in the service access door. (Port side aft of midship)
Now, look for an valve that does not make sense by its location. Nobody but the PO could tell you where to look.
In the head would be my first guess because that is where the cold potable is closest to the modified fill fitting. I hope that you can find that valve.
Now, about getting the potable pump to prime.
This may be a bear until you get the potable tank full above the pump suction level.
If you can - Great!
If not, lets work with what I see.
If the pump is dry, it will not do much even though it may not be hurt by being run dry, it also may just not do very much.
So, get it wet. Spin the nut off the suction side and find any hose you can that will jam on there and a funnel. Start the pump and pour in some water. There will be no doubt in your mind when it has enough water to work.
So, if you have potable to a level above the level of the pump suction, take the nut off the discharge and run the pump. There should instantly be water all over the place.
If there is not, there are two very good possibilities.
One is that the pump is shot.... That costs money, so lets look at the cheap one first. Unfortunately, PO left out the valve to make this easy. That thing with the four fasteners is a suction strainer. They can get clogged up. It might need cleaning.
Let us know how that goes.
There are two things in your pictures (good pictures - by the way), that bother me a little. (I am a ship's engineer by trade and am very much accustom to having to figure out what some prior engineer was trying to do.)
These are two spare Ts. One in the tank fill line and one near the drain valve. Where the lines from these lead cannot be seen in the pictures. I suggest that you find out what these are for.
I don't know how long you have inhabited the RV world, but as a Navy Sailor you know a lot happens by tradition and some of it still have meaning. That is why the big pipe for an atmospheric fill (you pour water in). These coaches were designed long before a FHU world was common. Many campgrounds (and some still) had only and open ended hose for potable water. Often that hose was attached to a hand pump. If you wanted water - There it was. This meant that to fill the potable tank, you had to be able to utilize water at "Standing on the Ground" dynamic head. This is still the case in many state forests. How you might do that with this coach, I would have to think about.
