Hello everyone,

I’m new to the 2-stroke with fuel-pump. And wonder’s if this is how you suppose to
put it together. ( see pic ) Or am I missing something?

Could the overflow go to the end of the tune pipe?

Any suggestion? ( other way to do this setup )
Your opinion will be appreciated

Thanks,

Hello everyone,

In the previous post of the tank set-up I was wondering the following, could I put a
muffler pressurized system with a check valve?
Will this do any damage to the fuel pump?
For the over flow I will put a fuel-dot.
(using all three outlet)

Thanks in advance for the info

The picture is how I do mine, keeps the carb from dripping when you fuel up. There are some rubber grommets at Lowes, Home Depot, that the fuel tubing fits snug into, on my latest I just ran the tubing those outside the fuse and joined it with a piece of Aluminum tubing. MK also makes some angled bulkhead fittings that work nice. Put your filter between the engine and the fitting closest to the nose, so you arent filling the tank through the filter.

I wouldnt hook it up to muffler pressure, doesnt need it, might just cause problems.

Oh and I think you can put a check valve on the vent, just so it lets air into the tank, it might stop the drips out the vent when the nose is pointed down when carried.

Hope that helps.

No need for a check valve. It will only create problems. You can run muffler pressure to the vent and this will help with the high end needle setting, but in most setups is not needed.

I use a single T in the supply line to the pump from the tank. Between the tee and the pump I put an inline Sullivan or Dubro filter. The vent line is out the bottom of the fuse....I also would NOT recommend hooking up the vent line to anything....just leave it open to atmosphere.

Ok, I’ll do this setup as chow on post Nr1 pic.

But I’ll put the overflow as seen in this pic.
Is this setup ok?

Ones again thanks,

HAPPY NEW YEAR!!

I ran my vent out the same way but the tie wraps kept coming loose so I used a 90 degree tee next to the opening there.

It will work fine setup there. no drips no runs no errors.

Have my RX set up the same as your diagram. The one exception is I have a YS check valve outside the plane on the overflow so it doesn't leak when carried or inverted. Some will say this causes problems but close to a hundred flights with no issues.

Anthony - don't you have to disconnect the YS check valve when refueling? That seems like the only "down" side, if there is one. I like the idea of it not dripping when being handled....great idea!

Yes, I do remove the check valve for refuels. I also disconnect the carb line if there is a long wait between rounds to prevent flooding. Generally, that is being overly cautious.
Much neater and better fuel economy this way. When practicing lots of inverted maneuvers I would land with raw fuel on the wing.

Ok, if I use the setup that is shown in post Nr 6 will also leak fuel from the pipe when inverted?

If so is this the best setup.

I’ll put a fuel T on the line where you could see a check valve, and by
doing this the new line become my over flow. I will put a fuel dot to do this.
