Outer Limits 4x4 Board

hey all i discovered a fuel leak on my injector pump it looks like its coming out of the fuel wind up screw well from behind it does anyone know if there is a O ring behind it or something to stop it from leaking is it as easy as pulling the screw out and putting a new O ring in it or is a pump off and pull apart job any help would be sweet

mate have you been playing with the screw to get more fuel?

there is actually 2 orings in there. you will need to mark the screw before you take it out.

one oring is in the pump housing the other is on the screw itself.
no need to remove the pump/

cheers mark

yea i moved it once i moved it about a quarter of a turn to give it a little more

as mud 4by said its just an O ring at the end of the mixture screw. get it from toyota as im told its a special rubber to handle the diesel and heat. measure where it is but you still wont get it back right will need a bit of playing around to get right. if you can unscrew it with out moving the locking ring your in with a chance.

its cool thanks i didnt go to toyota i got one from my mates at cheaper autos they has ones there that handle diesel and crap but all good now thanks
