Fuel Pump

[79XS11F]

Anyone have any experience with this sort of item? It is a fuel pump for the XS1100.

I saw that too...

I don't think its needed at all. Some one on ebay looking to make some money on uninformed buyers. The only use I can see is if you wanted to add an auxiliary tank for more capacity, you could use the electric pump to feed from the second tank to the main tank and or carbs directly.

That is the most ridiculous and irresponsible thing I have ever seen!
On gravity feed fuel systems?!
Be great on the boat, but not on ANY motorcycles. Nothing but trouble for any one who doesn't know any better!

I was thinking more along the lines of not worrying about the flooding that many carbs on these and other older bikes are prone to. Would be nice to set the petcocks to prime and be done with it. I wonder what controls the on off function and if it's just alway on would it flood the bowls anyway if the float valve leaks?

WTF......

hey there folks....if ya are worried about gas flowing when the bike is off, i gotta couple fuel shut-off valves that i will sacrifice for $125......ross

p.s. this ebay item is nothing but trouble....gas is gravity fed into the system....pressure on the system would make for a bad running bike.....like adding a electric fuel pump to a car that has a manual one.....stooopid!!!

Well let's see. The carb float valve leaks with just the weight of the gas in the tank above it. Now it won't leak with 30 PSI of pressure on it??!! Float valves aren't designed to have any more pressure on them then the (roughly) 6" to 1 foot of head pressure pn them.
As far as the on/off function, it would be controlled by whatever switch the user installed to control it.

I agree that this is a terrible idea. Gravity does an excellent job of feeding fuel to my carbs. I would be too worried about over pressurizing the fuel system to enjoy ridding if I had this thing installed. Aslo, it's ugly.

Pump?

Later Yammies had fuel pumps. I have a '89 FJ I'm working on and it has a fuel pump. Nice when doing synch or tuning as it will pull fuel from the tank on the floor and the output pressure is in oz's not lbs. The action is a diaphram that is pulled back by a solenoid and forward by a spring. No electric power = no fuel.

fuel pump

electric pumps are common on newer bikes even on bikes with tank higher than carbs. my bike runws fine and even if i wanted one i would go to the junkyard and get one off a honda car carbed car
no pump better than honda.
as ever bill

ps suzuki gsx1100g has one and tank is
higher than carbs

Read the add. So what is "fludding"?

[Pat Kelly]

I too noticed the "fludding" and then saying "it is a smart pump" in the next sentance.
Maybe the pump is smarter than the seller?

Question ... If the pump is pumping fuel into the bowl all the time any openings below the full line in the bowl would simply become an always flowing fuel line ... right?

pump

pump stops when it reaches 2pounds
float valve stops fuel, pump is a good idea
but i'm cheap and i don't drive much over
90mph.
