Just an FYI for the thread. I bought the cheapest ebay kit I could find with the "Custom Parts High Quality" brand CSTP-382 HFP-382 pump in the kit. Nothing was used but the pump so it all worked great. I'd link the ebay seller but the item I bought for $18.78 is now shown as $118.78??? So if you want just buy the cheapest CSTP-382 HFP-382 pump you can find and reuse the stock parts.
My bike had 196,800 miles when the pump was replaced. My symptoms where like everyone else, lots of surging when riding the bike. The last ride was a ride home from a trip, 550 miles of the surging but it made it home.
just an update, the pump has worked fine for over 3,000 miles. If you need a spare the ebay site is back at $18.

Well my second pump went out last Friday. This one was a lot different. It chugged as in "quit running" for 1/10 of a second twice as I rode down the Interstate at 75 gps indicated. I thought hmmm as it is the first problem I've had with the bike in a LONG time. And then 2 miles later I came up on a Semi and as usual I gave it a little gas to get around him and be done. Well it didn't go, It chugged hard if I gave it the gas at all and then died out but luckily I was just at an exit. So instead of passing I went right and got off the I-10 to check things out.
My first pump failure as quoted above got my bike to 196,800 miles and I remember it well that it bucked constantly for 550 miles home without me stopping along the road and I made it very roughly running home. Not so lucky this time. When I pulled off the I/S that was it. It died and would not restart when warm. I had just filled the tank 60 miles back so it had "cool fuel" but nope not gonna run. The second pump made it too 362,178 miles. 165,378 miles on (cheap) pump #2.
Black Pearl got it's third ride on a trailer back 60 miles home (thanks son in law) unloaded into the garage. The next day I replace the fuel pump with the quoted above $18 ebay fuel pump. I have 1181 miles on this cheap cheap pump and it's running as good as new. And I ordered another cheap spare to carry in the trunk for long trips. This one is for a Yamaha R1 so it should be enough PSI for my lowly ST1300. The old pump started the bike only twice after the first "time of death" and I tried it sitting on top of the bottom tank while it was all still hooked up. It sounded like sand being ground up inside the pump!

FYI, I only replace the pump. No other parts. Still the original filter and hoses. The pump replace is as simple as unplug the old and plug in the new. Same connections all around.
WARNING be careful around the sheetmetal edge of the lower tank when you pull the old pump assembly out. That edge is about as thin as a tin can edge and I'm thinking the seal comes from the super thick rubber gasket pushing the thin edge down and kind of into the rubber gasket. I stupidly got a small section of wire under the gasket and had a bad fuel leak when I filled the tank. I drained it back down, pulled the assembly and saw the bent tank tin edge. I straighten the tank tin edge back and gave it a bit more "up" after seeing the gasket design. No leaks now and still on the Honda factory gasket there too.
The new part has came already and this $21.49 delivered pump looks the same as the old. Pics of old (not Honda) and new R1 ebay pump.
