I was having issues over the summer with my fuel pump fuse blowing frequently when it was hot outside. If I waited for the bike to cool I could replace the fuse and ride it home. This happened most often when it was hot out, the bike was hot, and there was less than a half tank of gas. I decided to pull the fuel pump after reading about the issues with the chaffed wires but I do not see any chaffing. Does anybody have input on what else the problem could be? | ||

While it is out I would probably replace the input strainer, and output filter. Can you take the pump out of the mounting bracket and look for the part number? Not sure if it is the same Walbro 521 that the earlier years have used. What I'm getting at is I would probably replace the pump too, but I don't know what to recommend for the newer cycles. Earlier years can be purchased at Autozone for about 1/3 the price of a new complete pump assembly from the dealer. | ||

The pump needs replacement. There was a bad batch of fuel pumps on 09 XBs that cause the fuse to blow when low on fuel on a hot day. I am not aware of any repair methods other than replacing the entire pump. | ||

I had this problem once, looking for the eletric diagram i discovered that the problem was the engine temperature sensor. | ||

This posting has the details of the '09 fuel pump part number. I had no joy with getting it replaced under warranty so gave up and did it myself. http://www.badweatherbikers.com/buell/messages/384 2/694050.html?1348303934 It can definitely be replaced by the earlier pump - it is the same physical size, same electrical connections - just a different size pre-filter fitting. | ||

Interesting, did you try to contact Airtex to see if they could offer a cross reference based on the info you had at hand? I bet they make a pump that will work with the correct year input strainer and then that pump can probably be sourced at the auto stores. | ||

Thank you for all of the input guys. I am going to try to source a pump and replace it. I am going to try to find the pump that will work with the newer input strainer. I will let you know the part numbers if I am able to find one. | ||
| Greg_e |
I would suggest looking at newer Ford pumps for the answer. | ||

Greg, I'm in Australia so unfortunately don't have these sorts of pumps stocked locally. Personally I would stick with the earlier style pump because you can still buy the small pre-filter as Buell part. The later style pre-filters aren't listed as a replacement part in the Buell parts list. I also have an '06 Uly so in my case I can stock a common part that will suit either bike. | ||

I just ordered an AC Delco EP274 fuel pump and Airtex FS220 strainer to rebuild my fuel pump assembly. This pump is compatible with the newer bikes but you just need to get the correct strainer. I am also going to stop at Autozone and pickup a FF3330 inline fuel filter. | ||

I bailed on the Autozone fuel filters and found part numbers for Wix and Fram. I personally went with Wix but here are the numbers for some more fuel filter options. Wix - 33095 Fram - G3606 | ||

How much was the Delco pump? The Airtex from Autozone was around $100 when I rebuilt my 03 assembly | ||

I was able to find the AC Delco pump on close out for $47 at RockAuto since the pump has been discontinued. They also had the strainer and filter. I got two of everything for $125. | ||
| Xbtwelver |
I just received all of my parts however the Airtex FS220 strainer does not fit the AC Delco EP274 pump. I am returning the strainers and purchasing them from the Harley dealer. | ||

I got everything put together and took it for a quick ride today to fill the gas tank. I appreciate everyone's input and help finding information on this issue. Now I can't wait for summer! | ||

Hmmmm... I once had a random fuel pump fuse blow on my '09 Ss. Think it was low on fuel at the time, but I don't recall it being particularly hot out. Only happened once, so I just started to carry spare fuses and haven't given it much thought. But this is the first I've heard of a batch of "bad" fuel pumps. Is it something I should worry about, like it might have a more serious failure at an inconvenient time? The pump on my '03 XB9r has been the one that's concerned me more - it's pretty noisy... | ||
| Greg_e |
My 03 9r was getting really loud, that's why I changed it. I consider it money well spent to make sure I don't break down while riding. If it has never been changed, it is getting a little old and might be worth the time and money. My input strainer was trashed and not sure about the output filter but all that got done while I was doing the work. I don't consider it worth while to pull the assembly and just change the filter and strainer, the pump is $100 or less depending on how much looking you do. After putting a 1050cc kit on mine, continuing to put fresh parts on it just seems logical. | ||

After riding for a while with the AC Delco pump, I would not recommend it. Now instead of blowing fuses when the bike is hot, the pump just can't handle the heat and cuts out. I then have to wait for the bike to cool and it runs fine again. When I have a full tank of gas it runs fine because the fuel keeps it cool enough. I have been lucky enough to locate an OEM pump only without the entire assembly that I will be reinstalling. Just a heads up for anyone thinking about using the AC Delco pump. | ||

I was blowing fuel pump fuses too on my 09Ss. Switched to Amsoil full Synth, didn't blow a fuse for a long time. Then had a burn out on a hot day when my fuel tank was low. I try to keep my tank over 1/4 full, carry extra fuses and I haven't had a repeat in a long time. | ||

Has anyone tried this or a reflective heat blanket material as an option for keeping tank/fuel heat down?   Just wondering if it would help with the pump overheating issue. | ||
| Gregoxb |
Not sure if that would help with this specific issue. Is that your bike? What was your reason for putting it on? How long did it take you to do? | ||

Yes, my 07 STT, frame gets really hot up here in the mountain desert valley that Salt Lake is in. Felt like my leg was blistering on a ride around town the other day so I decided to give the reflective tape a try... see if I can keep the frame and fuel from acting as a giant heat sink! It took an afternoon (couple days ago), with more time taken due to my being a perfectionist. Rotating the engine has gotten to be pretty routine, still bugs me to have to pull the muffler, but as prone to rust as they are I don't mind touching it up every so often to keep it looking nice. Anyway, my bike doesn't pop fuses for the fuel pump, but the dang frame gets so hot in the summer, and I've seen some different options for dealing with that discussed. Have to get the muffler back on and take it riding, got sidetracked finding nylon washers for the body work. I'll be happy to post up if there's a noticeable difference in frame warmth. | ||

Well without a temp gauge or a hand held temp reader I can't say that it's done any good at all. I did notice the garage didn't stink of fuel after riding, which is an improvement, so I think it must have dropped the temp a little. When I got home I also noticed that the plastic under seat cosmetic fillers are impeding air flow, so I popped them out. Gonna be running around on it some more today, we'll see if that helps keep the frame temp down too. The ethanol fuel and winter oil blend (with 1qt 10/40, the rest 20/50 Mobile 1) might be part of it all too. (Message edited by littlebuggles on June 26, 2013) |
