Fuel cap fitting question
 

Hi Gang,
I'm trying to figure out how the fittings go on the cap.
Heres what I jhave.
1.Hole 1 takes the intake fuel fitting that my hand pump will draw fuel from.
2. Hole 2 has a fitting called * PROBE RECEPTACLE*.
I put that in and tightened the nut then inserted what is called the *FUEL PROBE*
No instructions came with the fittings so i'm assuming the soft fuel line goes to the suction side of my hand cranked pump.
Then I have the recoil line that comes out of the discharge side of the pump.
So that must leave the exposed fuel probe to hang up the end of the fill end of the recoil line?
If thats the case i'd just rather go with a check valve and a filter on the end of the line.
What/how are most of you using as a fueler?
Thanks :confused:

A filter is a good idea,

But (I think) a chack valve will prevent You from draining Your tank, unless You pull it off each time. "If You even worry about draining the tank."

On My old fuel caddy the pump (manual big six) is mounted on the side, Soft line to the cap fitting that has the pick up tube and filter. The other line (recoil) has another filter and the stem from that filter fits snugly into the second cap fitting. (probe recpt)

I don't use that set up any longer, as the jug will vent around the "probe" fitting.

Wow" You posted this yesterday, Sorry it took so long for a suggestion :-]

.Hi DAn,
Thanks for the info.
I sort of thought that was the way it went but wanted to make sure because it seemed like it wasn't right to fill up then hang the fill hose on the fuel prob..
Well at least the air that gets drawn it is filtered.
Thanks for the post :)

You may have miss-interpreted My explanation?

I found an in-line filter, I put on the end of the fill line that fit snugly into the cap (probe) fitting, and it stays on the line when connecting to tank line for filling.

I don't think you've got it. You don't hang the line on the probe. The probe is on the line and inserted into the receptacle when done, as stated. See......

A big circle in needed.
 

Hello, I think 4*60 is correct. It was hard for me to understand what was meant by "hanging up the exposed probe etc. etc." The whole idea is to try and keep air out. The Tower / GP photo that 4* posted, shows the fuel probe / filler INSERTED back into the bottle cap. That is the END of the line. (literly and figuretivly)!! The other fitting is the pick up fitting. From it's bottom end, the pick up tubing and clunk is attached. Here is the "CIRCLE". Fuel starts at the clunk, and is drawn up and out of the jug through that fitting I called the pickup fitting. An EXTERNAL line is attached here that goes to the input side of the pump. (manual or electric}. From the pump's output side, attach your fill line, (coiled or regular), with the filling probe on the other end. Just insert the probe into the plane's tank line to fill, and when finished, insert the probe into the probe fitting on the cap. My brand has an O ring on the probe to help seal the fitting to keep the air out. That is the "closed circle/loop". You could turn on your pump and have fuel come up out of the jug, through the pump, and right back to the jug. Why do that you ask?? :D Put it in the tank!!! :D ..Hope that helps....

PS. A lot of other people could have probably explained this with a lot less wording! :rolleyes: My wife always tells people, "don't ask him the time...... he will want to build you a watch"!!! :D
