Holley fuel leak
 

I think I found another contributor to my carb issues lately. It's a brand new 750 dp so I don't know why it would be leaking but it is. It's leaking from the very front, where that little arm is that presses on the carb to shoot more fuel, by the red spring. Sorry it's my first Holley I have no idea what it's called lol

Here's where it's coming from

the accelerator pump try and tighten the screws if not need new pump

The diaphragm itself seals the pump as it is sandwiched between the pump housing and the fuel bowl.

Just check to see if the screws are a tad loose. Don't get crazy and over tighten them. You strip out a hole and you're in for a new fuel bowl.

Cool thanks you guys I'll check it out and report back.

Check the gasket if it still leaks after tightening, could be folded or torn. If the gasket is fine and it still leaks, likely the diaphragm as a guess.
