TEE FUEL PUMP FITTING
Addressing the previous reviewer: This is not common but can happen. The parts involved are pipe thread so each have a taper to them. This could possibly fix itself with a different AN822 but most likely it has to do with the KB 90 T being tapped a little deeper than normal. Easy way to fix this would be to simply sand down the length of the AN822.
Use extreme caution with this part. Threading an AN822 fitting into the 1/8 NPT hole will result in the fitting partially blocking the fuel flow through the part.
