Yikes.

Was your pump working at all? What do you mean backwards?

Yes, it worked after I reversed the plates. If you look at the pump you have fuel flow directional arrows cast in on the pump. 2 for the pickups and one to go out toward the fuel pump. The arrows pointed in on pickups and pointed in on the output to the fuel pump. And since my fantastic brain told me THAT DON'T LOOK RIGHT I switched it around so the arrow pointed out at the fuel pump side

I've noticed that when you pour a small amount of gas in (not from a gas pump) AND the tank is almost empty AND the bike is leaned over on the sidestand, there's a tendency for the gas to run into only the left wing. When than happens, there's not enough gas sucked up into the pump to run the engine...you need to have gas in both wings when you're down to the last drops of gas. Maybe that's what happened in your test?

I do see fuel in both fuel lines from the wings and fuel being pumped by the vacuum pump into the reservoir so I think I'm good

I only put in about 3/4 of a gallon so far. I'll go fill it all the way up now that I know there are no leaks

Here is what I did to solve that problem, I can get every last ounce regardless if one wing is empty or not. 10Cup Safari Mod

I'm aware of your mod. I'm definitely not brave enough to attempt it.

Going back to the stock Safari setup --

1) if one wing is empty will it run as if it is out of fuel?

2) once both fuel lines are fully submerged again is everything back to normal?

And lastly, an unrelated question

3) Does your Safari tank have a little play in it? Nothing is rubbing on mine like it was for hf but if I push on one of the wings there is a little play back and forth

Thanks

Not 10Cup, but since I'm running a stock Safari setup I'll butt in--

Yes

Yes

and Yes--the tank mounts are rubber mounted with plenty of "give."

There's been a little talk here about the Trak Master 120. Here's a pic of mine I just spooned on. I think it fits just fine.



I specifically chose this tire in this size because of how tall it is. I think 27.1 inches if I remember right. Add the tall seat and my X/R finally fits me!

Like Hardworkingdog said, yes, once the vacuum pump gets any air it can't pump any more.
I also found that during the last 1/2 Gal. I could not get enough fuel to run down the interstate at 70mph. I have a short stretch I get on at the end of most rides. After the mod no problem with that either. Keep in mind I could run 45-50 but that was it.

Yes, the vacuum pump is self priming, so not problem once you get fuel in both wings.

Yes, and that is good. I had one of the first tanks in the US and I did have to put a 1/4" aluminum plate under the rear mount so that it fit better and matched the angle of the seat. It has been a bullet proof tanks and even when hit by a 12 point buck with resulting crash protected my radiator. Me not so much.

I would say there is about 3/4 inch space between flap and tire. Axel is back about 1/2 inch from forward position. 49 tooth sprocket. Not sure about chain length, a size up from stock though.
