Zenith carb.....I pumped Sea Foam directly into carb....trucks running fine right now, probably junk from tank, I removed the tank and treated and sealed a few years back.

Truck has 18,000 miles, no rust, could use a new paint job, missing nothing from top to bottom...I love the truck, but it has been a bit tempermental(sp)....

Thanks for your response, what would cause a vacuum leak, where?

Have a grateful day!
