Product Endorsement

OK it's early, but here's my initial reaction. The aftermarket automotive fuel pump previous owner had installed on my Yamaha failed in that it would run for only about 10-12 minutes before ceasing operations. A 10 minute wait would get me back on the road for another 10 minutes but this is obviously not going to cut it.

Fuel pumps of the type normally fitter to the bike are available on e-bay at prices ranging from $15 to slightly over $500. Go figure. The same pump seems to be pictured in all ads. With some skepticism. I got one labeled "high performance". Not sure what that means in a fuel pump but aftermarket parts on e-bay tend to be factory seconds from China so any additional endorsement helps. Price was a bit under $21 so not bad, and it ships from CA. Surprisingly it arrived 3 days sooner than I had expected.

Not mentioned in the ad was any useful specs like flow rate or pressure. Not mentioned on the pump is any indication of inlet or outlet. You have to figure this out yourself. Put a few drops of gas down each of the hose connections and put some power to it and flow direction will become immediately obvious. Hose size is 5/16" which of course I didn't have lying around. No big deal. Pressure turns out to be about 3 psi which is fine for a carbureted motorcycle. One more thing: This is possibly the noisiest fuel pump I've ever dealt with. The rattle from this thing rivals the exhaust noise. It's louder when there's no fuel in it so I suppose it will be easy to tell when I've run out of gas. Or maybe it's just quiet in the garage by myself.

I'll take it out on a test drive today. I expect it will get me there and back again with no problems.

UPDATE: OK under normal running conditions I can barely hear it at idle so I was right about the garage being quiet. Forget what I said about the noise.
