I want to run a vac gauge to see if I have a vac leak at certain points, the plan was to just tap the line with a T fitting and run a hard hose into the cabin.
Im moreso doing this as an experiment/real-time check. MAF seems to have vacuum from the inside of the manifold, as no vac lines appear to be routed to it externally.
Would it be ok to tap the FPR vac line?
Hopefully someone can let me know here soon.
