l series mechanical fuel pump cam slider the same?

[City Hunter]

I'm converting back to a mechanical fuel pump on my 72 z which has a 280z fi engine in it right now.

 

I got a fuel pumper slider deal that goes on the cam bolt to trigger the fuel pump but it seems to hit the valve cover on the l28. My question is, is the l4 engine slider deals different than the l6? Or is my valve cover off this fi engine slightly different.

no im going carbed since im too lazy to fix all the busted fuel injector lines and swap manifolds back over, I have everything but a heat shield right now.

the pumps should be the same if it hits the cover you may not have the right pump.

You mean the cam eccentric that works the fuel pump arm? All L series should be the same. When you put the pump on did you remember to put the 1/4" plastic spacer between the pump and the head??????

the pumps should be the same if it hits the cover you may not have the right pump.

 

dont ya need a spacer thing to go between the pump an head

[philip1]

oops forgot about the spacer.... yah if thats not there the arm will hit

yeah found the problem. The inline 4 l series spacers are different than the inline 6. There is a small portion that sticks up past the head I didnt notice. You are right though the eccentric is the same, but I grabbed a spare just in case.

 

Thanks.
