I have a mechanical holley fuel pump on my 302 and it makes a ticking noise on and off as the engine revs off of an idle, you can't really hear it at an idle, and at steady speeds it comes and goes, we though it was rocker arms, but my dad used a hose and heard the noise coming from the fuel pump, pulled the fuel pump and sure enough when I push up and down on the arm it goes tick tick, like there is some free play before it actually pumps again, is this normal or isn't it?------------------

Before I upgraded to electric, I ran a Holley mechanical pump, and it didn't make any noise at all. Any idea how old the pump is? I'd remove it and carefully inspect the cam lever and fulcrum for wear. ------------------

It is almost brand new, it only has 900 miles on them, but it sat in the box for 2 years before I put it on.------------------

When I bought my motor it came with the chrome holley pump on it.The first time I went to the strip I made 1 pass and then the arm broke off inside the pump  ------------------

No, the Holley pump should not tick, I had the same problem with a Holley street pump. The actuator arm had slop in the connection to the pump rod inside the pump. Holley exchanged it for a new one. Of course having Holley Hq here in Bowling Green helped. If you still have the original paperwork, call them.Mike

I found the problem, it was the little spring on the top that keeps constant pressure on the eccentric was broke, I had an old one that has a broken diaphram, so my dad took the old pump apart and put the good spring in the good pump since the pump is out of its "90 day" warranty. So the pump should be o.k. now, when I get the intake back on, hopefully tonight, I will see if it still ticks. Thanks for the help, Brandon.------------------

Yep, that is what it was, the tick is all gone, and I think the intake was leaking for sure because it definetly feels stronger now, especially down low.  ------------------
