Is my tank upside down?
 

Another quick question. I went to fill my tank, and after about 4 cranks I had fuel going into the muffler. I figured I'd messed up the lines. Switched the lines, but still fuel moving into the other line after a few cranks. Is my tank upside down? Thank you.

The end of your vent line that goes to the muffler must be facing down instead of up like it is supposed to be?

You will need to remove the tank and inspect and determine if it is assembled as per the instructions

I'm sick to my stomach. I epoxied the the end of the tank where it meets the firewall. This is going to take forever.

Model plane tanks are a real trouble maker. I usually have to redo my tanks every year.

So make them easily removable

Got it out! Any tips for getting the stopper into the tank? I'm about to lose my mind!

RE: Is my tank upside down?
 

I'm assuming that the stopper assembly is still epoxied into the firewall?

If you got it loose, you need to be able to loosen the the screw to relax the rubber stopper so you can reinsert the stopper assembly back into the tank.

Make certain that you have the vent line bent to where it goes to the top of the tank and the fuel pickup/clunk line can move freely and not touch the very back of the tank.

I use RTV silicone bath tub sealer around where the stopper assembly sticks through the firewall. You can usually cut it loose with a hobby knife.

Better yet, never ever stick or glue a stopper plug into a firewall hole this is really a poor practice and highly likely to cause foaming problems. Back the tank up a little you can let the fuel lines protrude through if you like.

What about all the old oil and fuel the will go into the hole?

Its seldom a problem and certainly not as big a problem as the rediculous practice of hard mounting and glueing a tank to the firewall and then turning aroundand padding the rest of the tank with foam? thats absurd. Or now this gentlemen who probably will end up destroying his tank getting the thing out.

If a simple hole bothers one just make the thing smaller with a bit of balsa or something.

You must have never owned a four stroke?

I always thin epoxy the tank compartment anyway

With sealing the hole with RTV it is easy enough to get the tank and stopper from the hole

It obviously is not so easy for this gentlemen as well as the many others I have had to end up helping with this problem. Its an exceedingly poor practice and problamatic most particularly for newbies. There are many far better ways to set up a tank and plumbing.

Yetti I highly reccomend you back up the tank. If the tank is damaged I would suggest using a Hayes type It cannot be inserted and is far easier to set up, in my opinion the most reliable and trouble free type of all the others.

One of my biggest complaints about ARF's is that they do not make the tank accessible or removable. I always make that mod to any one I set up. If your plane lasts more than a few flights, you will have to access the tank sooner or later.

Epoxy will let go with heat. If you can heat the area up without damaging anything else you can use a heat gun and point it right at the epoxied area and work the thing out a little at a time.

Hey, guys, thanks for all the replies. I actually took care of it and maidened her a day ago. She flies great.

Good job that all is well

the simple way to know if the tank is upside down is to point the plane straight up. if you have the lines setup right you should be able to fill the tank half way before the fuels reaches the vent tube no matter if it is upright or upside down
