Okay, so the petrol tank is all cleaned and painted and I'm ready to refit the fuel pump. The Haynes has served until now but it falls short of explaining how much and where you grease the new green o ring. Advice from the collective would be greatly apprecited. Thanks, Andy
Nightmare job! I rub grease around the tank rolled edges, then slowly, slowly, turn the screws down. Usually need longer spare ones to start the job. I also use the round/ball end of a T alllen key to push at the green O ring as it goes in. Bastard mofo of task! Good luck!
I can do one fairly easily/quickly now....Fecked a few up on the curve...:frown: Have you checked the price of the 848-1198 O ring?
I put the tank on an old quilt grease the o ring then place the pump in position and push down with the heals of my hands in a circular motion, always works for me. New o rings cost me 85 p each. Steve
Thanks guys, bit the bullet and just followed what I thought would be common sense. Now I only have to wait until I rebuild the rest of the rolling chassis to put petrol in the tank and see if it leaks. Andy
Could always put some in then just hold it up and look underneath, if it's leaking you'll see straight away. Also don't throw the old ring away, if you stick it away 'til next filter change you should find that it has shrunk back to original size. Can't explain why but I've done this several times now with no problems, don't think it's anything to do with being in contact with fuel as I found the same thing happened with the water jacket rings when I rebuilt Yam TZ engines back in the'80's which gave me the idea to try it on the Dukes.
