Fuel pump for larger tank question

[kengray]

I've recently received the larger fuel tank and a second fuel pump so that I don't have to switch the fuel pump back and forth when I want to switch tanks.
I was surprised by the size of the fuel pump and the fact that there are wires and electrical connections, that to my limited mechanical capacity, would appear to be submirsed in gas when the pump is installed in the tank.

I've attached 2 pics of the pump. Has anyone installed a fuel pump yet? Does this thing look like the right pump for the SXV?

Any help on this would be greatly appreciated. Thanks, Ken

Yep...that pretty much looks like mine when I removed it to seal a leaking seal/pump. Thismade the small tank mileage even smaller.

Be careful when fitting the pump, as I had one of the threads bind and spin the nut moulded into the tank

Could I ask why you would need to switch the tanks back and forth?

Match the weight and handling to the ride. The larger tank detracts significantly.

I, too, am surprise by all the odd-ball stuff hanging off that thing! It looks like there's a pickup tube, quite a large filter (when do you change this thing???), a pump, and one or two level sensors. Thanks for the pics!

Yet, inside the tank there is no risk of ignition. When submersed there is no oxygen. When not submersed the vapors are far above the UEL (Upper Explosive Limit) for gasoline which is 7.7 percent.

I'll use the smaller, stock tank for track use and the larger for street riding.

The pump has wires with plastic coating and also connectors.
won't the gas eat away at those and now I'm going to sound like an idiot, but won't the gas also short out the electrical connections. Also in the photo you can see a white zip-tie, surely that's got to be removed?

:chillpill Kengray...no disrespect meant...but just bolt the thing on and ride.
I've had my fuel pump in and out of the tank 10 plus times. There are tons of electrical coatings and connection that can be submerged in environments such as gas. The sytems seems to work well.

With as many problems as the SXV has...this does not seem to be an area of concern.


You should spend your nights worrying about..oil seals, o-rings, coolant and starters!!

No. Teflon insulation/wire-ties are not solvable in hydrocarbons. Also, gasoline does not provide enough conductivity to short between connections, especially at a low 12 volts.

(Sidebar: For those that don't know, pure de-ionized water is an excellent electrical insulator and will not short equipment. It is often used for cooling.)

I'm wondering what kind of mileage you get with the larger tank? Just wondering, cuz I'd like to ride it further than the edge of town...:bangwall:

Soon as I can get a bit of garage time, I'll get my new larger tank (from AF1) mounted and report. Wow that fuel pump setup looks quite the dogs lunch! :rolleyes:

Rather than change over tanks, can't you just put less fuel in the larger one, thus keeping the weight down if need be?

That was my thought too, but then I do have a habit of trying to uncomplicate things. Of course the fact that I bought an SXV does sort of negate that philosophy doesn't it?
I've got the big tank in my garage and the 550 is in the shop. Hopefully this weekend they meet.

That's an option, but then you have fuel weight sloshing around. Also, on my KTM, the smaller tank was less in the way of the bars and your legs. Sometimes, smaller is better!

We use a product in our larger gas tanks, to keep the gas from sloshing around and to aid in handling, it looks like foam, i forget the name at the moment.:cigar:
