Holley 135-10 GFLT Accelerator Pump Diaphragm

Good

You need this if you use today's gas. Ethanol proof.No leaks worked great.

They work great if you don't run E85 gas in your carburetors

On time and as expected.

Part was good but when I pulled carb I was only looking at the front accelerator pump which is a 30 mm the backside of the carb firewall side is a 50 mm so I’m sending 30mm back just trying to save the next guy sometime. Make sure you look to see if the cover of the diaphragm is the same depth on the front compared to the back float bowl
