Smallest in-tank motorcycle fuel pump

In yer experience, what is the smallest in-tank fuel pump you have seen? I'm talking about something readily available in the USA and from a newer motorcycle. Seems like the 2006ish GSXR600/750 is smaller in diameter and shorter in length than most. I do believe it also uses a single line, no return line system that is.

I have a pump from 125cc Peugeot Jetforce scooter. Not sure if they're available stateside, but I got mine from ebay, complete with tank.

It's a single line returnless system too.

Pump is about 3.5 " long and about 1 3/4" diameter if that's any help to you.

It needs to support around 80hp. Peugeot is not real popular here in the US of A but if it is a good pump and can provide the fuel for 80hp then I'd consider it. Ebay don't got one listed right now. You gotta pic?

Ahh, I see. It wouldn't be any good to you TBH. My pump will support upto about 25 HP, I'm using it on an engine which will produce about 15 HP if I'm lucky, which is the same power output as the Jetforce.

In your case, you'd be better served by your first suggestion of the GSXR 600. Yamaha R6 pumps also look pretty neat, and both are pretty easy to source on ebay.

I work at an AutoZone and so I see quite a few fuel pumps go across my counter.

Some of the car fuel pumps are pretty small. For instance, I've got a 95 Ford Mustang pump in my bike. It's pretty small and works well, and it's always available.

If you ask nicely and it's not a busy day, I bet they'll let you look through their stock and find something that fits.

Be sure you get a true EFI pump and not a feeder pump. Some cars have a low pressure pump in the tank which feeds an external high pressure pump. Those in tank pumps probably won't do the job.

One last thing, don't get too hung up on size as far as loss of fuel capacity is concerned. The pump is hollow and has fuel flowing through it, so you're not losing as much fuel capacity as you think.

I done fetched me a fuel pump for a 2005 GSXR750. It is actually pretty small for all it does. It is 7.5" overall length with only 5.25" inside the tank. The part that is inside the tank is 2.5" in diameter and the flange is about 4.75" in diameter.
It looks to have a fuel level sensor and an integrated fuel pressure regulator. I don't know if it uses only one line or if there is another pressure regulator on the rail and a return line back to the tank. I'll have to check Ebay for some throttle bodies and see.

Any chance you can post a pic and/or dimensions? Thanks!

No pic, but I measured another Stang pump. It's 5" long including the hose nipple on the end, and just under 1.5" wide.

i have the throttle bodies off of a GSXR 600 and there is no regulator on the rail. only one input.

does that mustang pump go in the tank?
