Fuel pump replacement/relocate

[Buzzard]

I was a bit disgruntled with the location of the external FI fuel pump on my 2002 LeMans. Deciding to do something about it, I realized I would have to make several changes. The air box had to go, I needed a smaller pump, and a smaller fuel filter. I would also need to go to velocity stacks with K&N filters. I found a pump by MSD, the auto ignition people, for about $110. Model #2225. Stacks and filters from Sport Cycle Pacific. Fuel filter is a Golan Mini in 5/16". I mounted the pump on the LH side, on a bracket made out of 1/8" aluminum, right beneath the front of the seat. I mounted the air temp sensor right in the end of the RH K&N filter. After installation, initial test ride indicated sort of a lean condition, stumbling off idle, slow response in mid range. I will add that this bike, which is new to me, had these symptoms before the change, but they were now more severe. I gave the TPS a spin a couple of degrees CCW, looking at it from the top. It runs fantastic! I like this mod, others may not. Of note, though, is that this fuel pump is a good replacement for the original if needed, at a bargain price.

Interesting mod Buzzard, how are your plug readings and what is the fuel consumption rate? Good to hear it runs well.

Since the mod, two tanks of fuel have yielded 47 and 45 mpg. The plugs are running a dark tan in color, which I am pleased with. Then the slow oil leak out the front timing cover became a gusher, so I've pulled off the cover. That's quite a bit of disassembly. I am relieved to have found a gasket with a blown out piece, right beside an engine mount. I was having horrible thoughts of a cracked cover. Looking forward to getting the bike back together in a few days, and get back to riding!
