Hey Folks-
I know this has been discussed, but what is recommended to seal the gaps in the pump tunnel?
4200 or 5200 sealant ? Seems like I've seen both used looking at other posts.
Also, what is the best way to pry off the intake grate without breaking it ?
 
5200 is more workable/sandable than 4200. Some have used JB weld, waterweld.

Thanks. Being in construction, I know Silkaflex products and they are top notch.
Right on.. if you do a search on this subject, I’m sure you’ll see the threads that have linked this product before

Here's what I did. Still holding on strong now 7yrs later.
