Fuel pump for Bike Carbs
I am trying to find a fuel pump to feed the bike carbs on my 1600 pinto. the fuel tank only has one connection so the system cannot be a flow and
return type. Hence the pump need to have an integral pressure cut off at a sufficiently low level that it will be shut off by the float valves.
I am aware that mini and morris 1000 fuel pumps would fit the bill as they have pressure switches set at about 1.5 psi and MG which were set at about
5 psi. However these are now getting on a bit long in the tooth and I wondered if there is a more up to date candidate out there?
Thanks

Just get a bike fuel pump from more or less any carbed bike over 600cc, my carbs were off a cbr600 hornet so I simply got the fuel pump off that
model, workes a treat.

As said, best bet is the matching pump from the same bike as the carbs. They cutout at the correct pressure and and don't need a return.

Thanks guys!
Is it just the pump I need or do I need the control relay as well?

Just the pump.
The relay on the bike it more to do with cutting the power when the bike goes on it's side, than because it's a high current device

Most are just 2 wires (chassis and +12v) so any relay would work.

I also wired one of these inertia switches in at the same time so it interupts the power to the pump in the event of a bump, didn't fancy the
idea of a fractured fuel pipe emptying the fuel tank into the engine
bay!!LINKY

I have an r6 pump feeding my zx9r carbs. works perfect and no need for a pressure regulator.

I was looking for those, so I could mention them in my previous post! I also fitted one, for pretty much the same reason. They're really easy
to wire in - when they're upright and set (you have to press the top in) then the 2 wires conduct - if the car's badly hit, or rolls over,
then the connection is broken. It can be wired directly into the pump wiring, or via a relay. I took the second option as I also have a security
system installed - if the security's not satisfied, then there's no ignition, the car won't start, and the fuel pump's off!

They're more important in a fuel injection set-up due to the higher pressures... but it's still not a bad idea....

I just used the standard mechanical pump and a filter king regulator at its losest setting, works fine.
