Does anyone know the exact dimensions of the O-rings for the fuel pump? A friend replaced the fuel filter and didn't change O-rings and now I have a leak. Trying to get this taken care of this weekend but HD can't get new ones in till Tuesday next week. My weeks are slammed and want to be able to ride. Not happy with my friend at the moment. [mad]

3 inches diameter....3/16th inches thickness
H-D part #---P0121.02A8A think it is 2 per pack. about $5 list price
also any advance auto parts or napa store has them for a bit less. they must be viton.

The outlet? Loosen it and adjust it to vertical, re tighten. My 9sx did that until I let the o ring settle again and got it tight.
Take yours off and go hardware store hunting. Match it up. Probably 1/4", 3/8" or 5/16.

HD selling 'em as each, just ordered 2 from newcastlehd.com $4.99 each...pretty much anything that normally comes as a set, HD is selling as individual pieces
I found the leak tonight it is at bottom of fuel pump. So leak is definitely being caused by orings. Didn't get a chance to hunt for them today so I will be looking tomorrow. Hope to find some but this small town doesn't have many options.

read what i posted. oye
Thanks lunaticfringe. Guess I should have read the whole thread. I am getting ready to pull my fuel pump and swap frames, figured new o rings would be good since its an 04. I didnt want to wait for Harley to send them to me or pay the shipping.

my pleasure. most all H-D dealers likely have 2 or so in stock as does most NAPA stores. they're fairly common standard size.
