Oh, sorry I met were do I put the sensing end of the hose. So there is a place on the block. I know, like you said bgilbert that the 91. 5 and up can us the hole buy the pump. I didnt know about the one under the throttle bracket. I was told to drill a hole in the intake crossover tube. I will check that out, I like the sound of that better then drilling into the crossover tube. Thanks
