Vent tube

Tony....is surely is a modified/shortened housing. The way the vent sits now is def no good to you if you want to use it as a distribution block anchor anyway so it’s coming out regardless as you’ve said. Looks like it may have been modified already as it’s appears to be pressed in. This is what I’d do but I’m not sure what you have for welding capability. I’d totally remove that vent. Try to tap that existing hole to the vent thread size. If the hole’s already too large, I’d find a nut that fits the vent thread, drill the hole out to the same size as the outside diameter of the nut, slide the nut into the hole flush at the top and give it a seal weld. Grind that baby flush and install your block and vent tube. you’ve got that housing already broken down. It might take maybe 2 hours.
