Gentlemen;
Adding the sediment bowel was a 'dealer item' and didn't come from GM on Chevrolet or GMC. It was used on farm tractors/machinery and ended up on cars/trucks as an accessory ONLY. The filter is on top of the fuel pump.
We fixed dozens of these on 30s/40s vehicles in the 1950s. It's best 'before' the pump to keep dirt away from it too and that's where we put them removing the hazard.
With two of them right above headers with porcelain is "triple" the potenitial for disaster is all.
No one is faulting your workmanship, It's just bad design. Please; don't compound that by leaving it in place and destroying your vehicle, after all that work.
Good luck.
