Re: Aftermarket fuel pump

Great news!

Can you please tell us how you were able to secure the fuel lines to CA cycleworks pump, as it does not have a barb, and some who have tried have had the output fuel line pop off under pressure.

HusaGlue. It's made from boiled marmots.

I used fuel injection style hose clamps (not the normal type hose clamps) . I tightened them not too hard and not too loose. I've only heard of one person on here having them pop off, is there more than one? I've got about 5 hours or so on the bike since the fix.

Re: Aftermarket fuel pump

Just thinking out loud, is the output of the CA cycleworks pump plastic? and if it is couldn't the very end be slightly heated with a small flame and then flared a little bit to act as kind of barb to help keep the hose on. Thankfully I have not had any of these issues, croosing all my fingers know , but maybe this is something can help others that are having this problem.

Re: Aftermarket fuel pump

Bigblue; had exactly the same idea in my mind. I plan not to use a flame but a heat gun instead, more controllable and it should not scortch the plastic quickly by accident. The pump is most likely thermoplastic so heat will soften it up. Maybe use some big iron nail or countersunk drill bit's head to flare the outlet slightly.

Re: Aftermarket fuel pump

It's just pure bloody odd that a High Pressure pump has no barb. Just my opinion not saying it is correct.

Re: Aftermarket fuel pump

You know, a funny thing happened on the way to replacing my pump - the old one started working fine.

On my first ride, the bike wouldn't re-start. It would fire, then die, then it'd have to sit for a few minutes. It sounded just like the overheating pump issues that everyone had. So I wrapped my header, put reflective tape on the tank, and swapped the coolant for water with water wetter. I also ordered up the aftermarket pump to have on hand, although I didn't install it.

While the second ride out wasn't nearly as hot as the first, I had no restarting issues except once just at the end of the day. The bike was stumbling quite badly though. So I ordered a new filter and pump screen. The stocker was 80-90% clogged when I swapped it out, despite me rinsing the tank out when the bike was new. Either I didn't get all the tank goo, or just running it for ten minutes at the factory and dealership during the PDI was enough to suck all that in.

I've done another few rides on the bike since. No really hot days (I AM in the Canadian Rockies after all...), but the tight and rocky singletrack that we ride has had the fan humming and the coolant bubbling at times (not the fuel as I originally thought), so there's plenty of heat there. So far it's fired right up every time. My bike is working perfectly. I no longer cringe when I go to re-start it. It is just a totally awesome and very cool looking bike!

Now if I could just stop falling off the thing on the big rock steps and multiple log jumps, I'd be set. Can't blame the bike at all for that though....

I agree they should have designed it with a barb BUT: to-date, has anyone besides BRN2RDE had the fuel line blow off the CA Cycleworks pump end?

Re: Aftermarket fuel pump

I've just started getting this pump problem after 65+ trouble free hours use on my 570. Happened again for the 3rd time in 2 weeks last night and as it was pretty warm with no breeze so had to wait for almost 1 hour for it to cool & restart. Then rode home as if nothing was wrong. The first 2 times it happened I wasn't really sure where the fault was so I took a small multi meter out with me yesterday just in case and confirmed it is defininately the pump or maybe the electrical connecters in the tank? Noticed last night while waiting for the bike to cool that the tank (and fuel in it!) was quite warm although not actually boiling. The header is wrapped and the tank underside has the foil blanket heatshield fix applied.What the hell going on with these pumps? When it fails it's completely dead, not even trying to spin slower and maybe give a reduced flow, just DEAD. There is NO indication of imminent failure, just straight from normal full power behaviour to total fuel starvation and engine cut. Then on restart sometime later, completely normal.
