Iwo Jima Fuel Pump

[Rsk_141]

Hi all,

Have found a fuel pump on my 1200 Inazuma .

Question is can it be removed and a gravity fed pingle set up be used ?

Don't see why not, it's all about flow. 

[banoffee]

Is the tap lower than the carb fuel intake? If so, that’s why you have a pump.

Its a bit of an oddball as the 1200 zuma has a pump on a similar set up to the 750 zuma but the 750 sont have a pump...........

both use the same tap location and both use 32mm carbs ...

i have a Fazer 600 tap on my 1200 engined 750 Zuma

Have just turned my attention to this project and with all these things I just  pull them apart and put back just the things It needs or I like . And the fuel pump I can't see the benefit, have the gsf model got them

The tap is above the carb level was going to junk the pump and fit a pingle I read the Mk1 gsf one fits

You dont need to spend pingle money $$$    good info here ref replacement tap

Cheers for the link All good stuff will bypass pump and fit  the Fazer tap to see how many liters I have left in the tank, and I'll take it from there .

Könnten Sie Mir bitte eine Link zu einer Kopie Des Handbuchs schicken?

Ah see the problem now the carbs are fed from below (see pic)

When you lift the rail I don't clear intake (see pic)

So would have to split carbs and replace fuel T pieces 

[richyrich]

But if the tank is above the rail and the carbs,  gravity should still flow !

For a gravity fed system that has to make a rise it will all be about pressure, a  2 meter drop from tank to out put will give you a pressure of 0.2 bar,  around 2.9 psi so 300mm will give you 0.03 bar around 0.04 psi which i Would imagine why the fitted a pump .

What? If the tank is above the carbs the only pressure you are dealing with is atmospheric which will be virtually equal measured at the surface of the fuel in the tank and at the fuel level in the float bowls. Pumps are only required when the float bowls of a carb will be above fuel level in the tank or gravity flow is marginal ie. levels are nearly equal ! The carbs in my daily have a pump as they sit within the tank shell and for half the capacity of the tank the level is below the float bowls!

[Rsk_141]

what like the first picture where the fuel rail is below the carbs float bowls . If this is not the case, what would you suggest the reason they fitted a fuel pump on the zuma 1200, too many fuel pump in the stores, and there was a stock check coming up? Perhaps .

Who knows !

Who knows? Maybe to justify adding a £100 / $200 to the bike cost for addition of £10 / $20 part (cost to manufacturer not spares cost!) There is plenty of crap added to bikes that don't necessarily need to be there!

Have a couple Inazuma 12s. The pump is needed to empty the reserve.

Without the pump the reserve is pretty much left in the tank.
