While a new bowl maybe super hard to find, taking your centesection and having the surface milled much in the same way a cylinder head is done would fix the top half.
The bottom half has an issue even with the well s removed. There are grooves on the bottom.
Has anybody ever used JB weld in the fuel bowl?
I used it on the front to fix a crack. The JB is on both sides of the bowl. No issues.
