Can someone tell me if there is any connection between modifing the exhaust and fuel leaking at the carb. I've not owned the truck for very long (couple of weeks)...what I can tell that has been done is that the egr vaccum hose is plugged, the converter no longer resided in the exhaust, the air pump is still there and apparently working? When the exhust was modifed I've noticed that sometimes gas is leaking at the base of the carb, before exhaust work it was not leaking. I don't know if this is just considence or is there some connection. I do plan on removing the smog crap.....since I don't have to deal with inspections where I live currently. The leaking gas business cf course concerns me and I need to get that fixed. Its so nice that the carb bascially sits on top of of the hot exhaust manifold (right near it anyway)... Truck seems to run fine.... after driving for a while I noticed the smell of raw gas and opened the hood to see that it looks like gas is leaking out of the drivers side of the bottom of the carb.
