I took the flexible line off in front where it connects to return. The hole was so small in the line where they crimped it i could barley get a 3/32 drill bit in. turning it by hand. so i drill it out a few sizes bigger. now vac line off at 43psi vac line on 36psi. BLM is now at 116-117 Looks like this part is fixed. now to the next thing.looks like from factory they crimped it to much very small hole. thanks for everyones help.
