??holley 4160 fuel bowls?

so both of my fuel bowls are leaking around where the needle and seat would be on a regular bowl, but being a marine carb, these bowls have no needle/seat to adjust, it's just some pressed in plug... my question is can i drive those plugs out and replace them or do i need to buy completely new bowls???!!!
i found new bowls on jegs but don't like the idea of spending 90 dollars if i could just drive the plugs out and press new ones in. please advise

thanks- steve

Ahh ok. no I didn't rebuild but the po did THEN put the jb weld job on them, but they still leak. I want it done right so I'm just gonna buy the new bowls

call holley i think i got them both for around 50. it took a few weeks because they make them to order . still have the old ones with jb weld . they dont leak and u can have them pay ship but no telling if they will leak.

They are very soft and mallable for a reason, no need to replace them. Take a hammer and you can 'reseal' them with a few taps and a soft punch(wooden dowel). My primary was leaking and this is how I fixed it. I started with a few taps in the dead center(angle the dowel a tad to spread and not drive down so much) and worked my way out in a pizza spreading kind of pattern. They don't see a ton of pressure so no need to fret too much.   

I wouldn't use jb weld. that's just a patch and you don't seal off the leak you merely cap it with an imperfect seal. If you 'reseat' it you'll effectively seal the leak for good.

update, tapping the plugs as john said worked, they no longer drip continually! the front may need a few more taps but that fixed both plugs on the rear!! tag this for future it could save you 60-90 bucks!
