68 tripower accelerator pump leaking "I think"

My 427 tripower has been sitting for about 2 months. Started it up to start driving it again and like to check for gas leaks. After warming up and removing the air cleaner I started to manually rev it up and at higher rpm's and it would squirt gas from the front and drivers side of the accelerator pump diaphragm on the center carb. Is it possible to try to tighten the 4 screws with the carb still on or does it need to be removed/replaced?

For those of you who have done this do I just have to replace the rubber diaphragm?

Sounds like an easy job right….

If I need to replace, does anyone have a part # please?

Thanks all,
JIm

if you can use a 1/4 drive racket with a socket and a screwdriver bit you can probably do it on the car.
Yes, if that doesnt work replace the diaphragm.
Part 135-5

use 135-10 as it is better for ethanol based gas.

Thank you both. I'm going to try Mels option first, but am going to order a 135-10 either way.
