Hi everyone -- this thread popped up on our radar, so I thought I'd join the forum and say hi. I'm the guy that makes the Ca Cycelworks pumps aforementioned in this thread. BTW,
why didn't the OP use our pump if he has one? If there's something wrong with it, please tell us so that we can learn from it and fix problems. Our pumps have been through 3 upgrades since introduction and I'd like to think they are the best option for pump replacement on the market.
Last year, I emailed a guy who had one of the Aprilia assemblies on his bench, and his and mine appeared to be the same size flange, you might need to check the wires and make sure that they are all in the same place for the Husky harness plug.
That 6 hole oval flange is made by Bitron in Italy and seems to be the go-to supplier of any Euro-made motorcycle fuel system that isn't designed in Japan (like Keihin, etc). If it looks at all like the Aprilia one, that's it. For Ducati, Bitron makes a dual port version to have a fuel loop to the injectors with a feed and return, with the pressure regulator being on the return's inlet. I have held 3 different versions of those flanges and the wires are always the same, the mounting holes the same, with wire lengths and hose connections being customized for the manufacturer (Aprilia, Ducati, Husky). It is a modular casting and design. And imho, the Bitron pumps are great OE quality and there's some other design error in the fuel system causing problems which manifest via the fuel pump failing. So far, our pumps (which we pay extra to get the best quality possible), are doing a pretty good job of masking the fuel system problems and let people keep riding. When I sent the OEM "Made in China" pumps to my people in China to confirm the design, they paid the pumps compliments for the quality -- and my contacts are not shy about saying when something is made poorly.
And for why I really posted: I / we understand and greatly appreciate the OP's frustration with hose!! When we started selling the pumps a few years ago, we didn't include a hose. We got yelled at. So without analyzing costs, we started including the same hose we used successfully for over 5 years on our in-tank products for EFI Ducatis. But somehow those weren't working for you guys.

So we upgraded to a better hose, which ended up bursting. So we went and bought a mile of NAPA's premium automotive 30R10 hose, which disintegrated. ( I was blamed for this and yelled at on the phone

). It seems that customer thought it was my intention he should have a failure??? OK then we started selling the braided "pink hose". I had lengthy conversations with the guy who makes it (in Louisiana) and he said it will swell and discolor but won't burst or pop off and is the best thing he has
or has seen on the market for resistance to ethanol. And we've been selling that hose and haven't been yelled at. Until again someone was super pissed at me, personally, because he, too, thought it would make my day better to hear he had to push his bike a mile... Actually, it ruins my day, makes me sick to my stomach, and causes me to lose sleep and/or drink more.
Now I have sought out a new, hard, plastic-like hose that's sort of similar to the OE hose that I hope will stop folks accusing me of having a sick plot to make y'all push your bikes. They're at FedEx now, so maybe we'll get them in a week. Like everything else; when you want quality, you call up China, explain to them what's wrong and ask them for the best fix for the problem. When you're not trying to talk the price down, they deliver quality that compares or exceeds what I can buy anywhere. These hoses aren't as mean as the heat-shink ones that Bitron uses, so hopefully they will be user-installable as well as ethanol resistant (assuming all these hose problems stem from that).
