Guest christo Posted January 7, 2004 Share Posted January 7, 2004 Whats the fuel pump excentric on the end of the cam for? I know its for a mechanical fuel pump but I haven't seen one yet. Does it have to be there? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 7, 2004 Share Posted January 7, 2004 To drive the fuel pump naturally.... Quote Link to comment Share on other sites More sharing options...

Guest christo Posted January 7, 2004 Share Posted January 7, 2004 OK it was a stupid question. I just haven't seen a mechanical fuel pump on the Z's I've seen. Quote Link to comment Share on other sites More sharing options...
BillZ260 Posted January 7, 2004 Share Posted January 7, 2004 I am not sure about the other models but the 260's (at least mine did) have an electric by the tank and a mechanical on the block. Dunno why but there it is. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 7, 2004 Share Posted January 7, 2004 Bill, I believe it was to combat vapor lock from underhood heat effecting the fuel in the lines. My 73 240 that I sold also had one...can't remember if I put it in, or if I bought it like that.......old age is catching up to me Tim Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 8, 2004 Share Posted January 8, 2004 I seem to remember that you need to leave the eccentric on there or get another washer that is the same thickness and ID because it has a shoulder on it and the cam gear bolt won't sit flat on the end of the cam without it. I know I've still got mine on there even though I've switched to an electric pump. It's been a while though... Jon Quote Link to comment Share on other sites More sharing options...
