Now another Problem (A major one for me!)

[Nemo]

Sunday, the trike's engine stalled on the Interstate. It had stalled once before, a month ago, and then I replaced the fuel filter and it has run fine. Since it reacted the exact same way again, I thought it had to be the filter again. But, when I unclipped the hose to the tank, the filter came out to me along with a section of heavier hose about a foot long. Now, I'm really in trouble, because I don't know where this hose came loose from. I believe that when I replaced the clutch slave valve, earlier, that I must have accidently loosened that hose. Please, can someone help me with some advice? I sure need it and would certainly appreciate it. The bike is a '99 RS Venture. Thank you! Owen.

Hey Owen,

I have attached a diagram of the fuel system of your 99'RSV. Take a moment and have a look at it and see if you can figure out what is going on there. Perhaps the previous owner put a longer fuel line on the line that goes from the filter to the pump.

If your filter is new, I would suspect the fuel pump is on it's way out. Just a guess of course, not ever seeing your scoot.

Hope this helps,

Earl

Could it have been the overflow tube from the plastic overflow tank.

Earl, Is there a reference page to match these numbers to the items? The hose that I'm looking for is attached to the large end of the filter (#28) and it looks like the hose (#30) has a joint in it before it gets to what I believe is the pump (#44), although I haven't looked for the pump yet. Does it look like that to you too? Thanks! Owen.

Hey Owen,

The fuel line that has the 180 degree in it is a fuel line inside a fuel line. I have attached another pic.

I think the PO installed a much longer line in place of #30.

This is still confusing! Here's the progress so far: From the gas on/off/reserve valve, the tube runs to a brass Tee under the seat. From the straight part of the Tee. a tube turns directly down from there and into a white plastic looking unit below (it resembles a filter). The side connection of the Tee goes to a tube that goes to the right side, down and toward the left rear. I can't see where it goes from there, and maybe that's the one that this loose tube connects to. Don't know. Now, opening the gas valve, no gas flows out of any of the tubes. Oh, and when I first turned on the key the fuel pump did run for a sew seconds, as usual. Driving me crazier!

Does the bike run now? Or not?

 

This might help us figure out if thats a fuel line or something else.

 

[Nemo]

No, it won't start. It stalled on the highway as if it were out of gas, but the tank is full. Something must be plugging up a tube or maybe it's kinked. Opening of the gas valve without the tube attached, the gas flows put properly. Thanks for your interest!

O.K. No have a look at the picture Earl sent you and I have reattached here below with the fuel filter marked, and tell us if it is the same kind of a plastic thing that you think is the fuel filter - just to make sure we are on the right track.

When you have verified that then tell us if there is a hose on the bottom part of the filter and if there is then trace that one and tell us where it goes. It should attach to the fuel pump that is behind the middle cover under your seat - the one that the side covers attach to.

The side connection of the Tee goes to a tube that goes to the right side, down and toward the left rear. I can't see where it goes from there, and maybe that's the one that this loose tube connects to. Don't know.

Trace that one to and tell us where it goes. Don´t remember this connector from my bike.

Now, opening the gas valve, no gas flows out of any of the tubes.

With the shutoff valve closed, trace the tube that goes from the valve to the point where it attaches to the fuel filter. Deattach it and turn the valve on and check if you get fuel running through.

Oh, and when I first turned on the key the fuel pump did run for a sew seconds, as usual.

Sounds like the pump and lines are fine since if the pump does not get enough fuel it will/should continue running.

Driving me crazier!

Last - check if the fuel filter is connected in the right direction - there should be an arrow on it that should point towards the fuel pump - not the supply/tank

1. The fuel filter (28), I had changed several weeks ago and then the engine stopped again just like before when the original filter failed. I'm not sure what the plastic looking thing is because it's down deep within other stuff. I said it resembles a filter, but larger.

 

2. The short piece of hose (30) on the bottom of the filter is the problem. It just kind of fell out, attached the filter, as I removed the hose from the other end of the filter and I don't know of where it became disconnected.

 

3. If that short piece of hose is part of another piece of hose and does actually go to the fuel pump, I don't know because both hoses from the fuel pump disappear among other stuff also.

 

4. The hose from that Tee and going down on the right side just disappears among other stuff and can't follow it. Also it's clamped down because it won't move.

 

5. On the fuel pump, I can't tell which hose goes to the shut of valve, but I disconnected one of them and opened the valve and still got no flow.

 

6. The filter is connected correct, but no gas is getting to it. Something is restricting the gas flow, and something is still open where that short hose from the filter had pulled loose. Man, what a mess! I hope this is about as clear a mud!!!! Owen.

Owen,

 

Is there an auxiliary fuel tank on your trike?

[Nemo]

Yes, there is an auxiliary fuel tank, and it's empty.

Is there a valve between the reserve tank and the original tank? Is it in the right position to allow fuel from the original tank to the fuel pump?

[Nemo]

Jim, that's good thinking, but this is Hannigan's Trike system which is different. It has a special switch and a pump that transfers gas from the auxiliary tank to the bike's tank when needed. There's no valve to re-position to do so, just flip the switch to refill the bike's tank. Somehow, there's no flow of gas to the filter. Thanks for asking!
