Baby fuel pumps?

Post by the bubbler »

Looking around for a supplier of fuel pumps for small engines (i.e. 300cc single).

Have found this, but no luck with a supplier yet-

Anyone got any other ideas/suggestions? I need something with a low current draw.

How about a pump off a small bike. There are plenty of injected mopeds about with engines up to 250+cc

Where?

I know Honda and one or two other companies make efi scooters, but they're spares cost an arm and a leg.

Haven't had much joy with bike breakers either.

If you know of a source, I'd be very interested to hear about it.

The pump is currently in INDIA, according to Delphi ISS, it would cost around 250$ and you couldn't get it only for youserlf because of the paperwork that need to be done for new products.
:?

Also looking for something small and low current draw

The Honda Zoomer in Europe (use the PGM-FI of the Honda DIO Z4 of Japan), had a price made from a dealer.. around 300-350 Euros. That's insane.
Synerject fuel pump is said to have a really really low current draw, you could check with a dealer of Piagio (something like that, vespa) and Aprilia. There's a inline and an in-tank fuel pump.
Mail me if you find anything.

I purchased a pump from a scrapped Peugeot Jetforce 125c scooter. Cost £15 for complete tank swirl pot and regulator.

I will build this into a custom swirl pot.

Also purchased the throttle body from this bike. A Bing model with a built in TPS and is 26 mm diameter choke (quite large for size of bike).

This also came with Synerject IAC valve and injector. Not sure yet of the flow rate of the injector, but i think it will be adequate.

So far, so good.

What kind of current draw are you looking for? I have one for my snowmobile off a mid 90's polaris RXL for about $30 that is only a couple amps draw. I haven't tested it at pressure yet, but it's a pretty small pump.

The Honda Zoomer pump draws about 1A according to the Honda website.

They built it with the deliberate intention of reducing current consumption- the PGM FI system has to be able to fire using kick start in case of a flat battery or knackered starter.

Still 2A or 24 watts is not an unreasonable current draw.

Unfortunately the cost of Honda spares off the shelf is horrendous. The only other alternative is to keep searching ebay for scrapped bikes. The Zoomer is very new, so you'd be looking for one involved in a smash.

There are some small two stroke DI pumps as used on the Aprilia 50cc scooters.

However these tend to pump at higher pressure than required for port injection. Perhaps they could be modified for four stroke use?

Something like this-

I'm gonna try the aprilia sr50 fuel pump I just bought and give feedbacks to you guys. Hopefully it won't have a big current draw... and yes the fuel pumps from honda cost a lot (had a price around 300 euros)

The Aprilia pump (synerject piston pump) draws about 0.7A according to Orbital. Can also pump upto 7.5 bar, so use a port injection regulator.

I think you'll be fine with this pump suitable for engines upto 7.5kw.
