I've recently install tbi on my K5. I drove it about 20 miles today pretty hard and fast. When I pulled up in the yard I notice a liquid pouring out of the front. I thought great I've blown a radiator hose. After close inspection and a sniff I realized it was gas coming from the vent tube. I released the gas cap/pressure and it stopped. I'm thinking that I need to switch my vent and return line at the sending unit. What do yall think? I'm at work now until midnight so I'm trying to think out loud about this. I've got to have it fixed by Wed cause she'll be loaded up and on the way to ECBB thurs morning.
