I need some info for KMS EFI kit, especially for the fuel pump.
Any brand, specs, model # ?
Is there a list of the EFI parts ?

 

Welcome Funduro,

There are several guys on this forum that have the KMS fuel injection on their DS, hopefully one of them will catch this thread and give you the details of their fuel pump.

Tell the guys here about the system you are putting together.

 

i'll haveta dig thro my stuff and see if the papers have any numbers on there for ya, will let u know

 

if the paperwork doesn't list fuel pump specs, maybe take a look at the pump on the bike, see if there is a label or i.d. sticker that tells make and model, specs, etc...

 

hey, chris ... i dont mean to jack this thread but send me a pm if you are still doing a big dune trip out west this spring i am interested.

 

My setup consists of
Aprilia Pegaso 650 IE 2x34mm dual throttle body (overbored to 2x36mm),
2 x Sagem high impedance injectors (150cc/min),
a pressure regulator 1-8 bar (variable) with gauge,
Megasquirt v2.2 EFI controller (fuel only),
Sensors (TPS, MAP, MAT, O2, CLT, Baro),
High pressure fuel hoses.

I need a fuel pump (150LPH/3.5-5bar)
and stator rewinding or F650GS stator (400w) later on.

 

I have an adjustable fuel pump on my busa bike I baught from dragbikedirect.com you can run any pressure you need they are great but a little pricey.

 

sorry bud, my paperwork doesnt have any specs in it and the fuel pump itself on my bike is bare, no labels, unless we are unlucky enough where the label is right where its attached to my frame lol

 

Thanks guys,

NickDS650 maybe KMS doesn't want to reveal the pump's brand & model. It is somehow expected. I respect that.

I have the specs of the FI F650GS fuel pump (150 LPH / 50.7 psi = 3.5 bar) which shares the same motor but,
I am not really sure if the flow rate and/or pressure is enough for a tweaked motor like mine.
As long as I have an adjustable fuel regulator, I could go as far as 5 bar fuel pump and regulate it in 3.5 bars.
That means I will get 5 - 3.5 = 1.5 bars of pressure in return line (to fuel tank).
Is this normal return line rate ?

Is there a schematic of the KMS fuel lines assembly, because I am wondering where to connect the return fuel line.
Normally it connects to the fuel tank on a dedicated hose but I only have one petcock. [img]i/expressions/face-icon-small-wink.gif[/img]
The other solution is to connect it back to the low pressure circuit, just before the pump, using a Y connector.
What is the case with your KMS systems ?

 

KMS used to run the return fuel line to the top of the fuel tanks cap so that it looked like a breather hose.
