Howdy everyone,

So I think the next project I need to address is the horrid fuel smell. My car is a 1972 with twin Weber IDF's. Nothing is connected in the frunk. My plan is to order some cloth braid hose from Belmetric and reconnect everything up front, as well as possible a filler gasket. The engine compartment is a different story. Where is the pressure tap off the fan housing? I can't seem to find it. And then, what have people used to cleanly attach to the generic IDF filters? I went on a date today (first date in 23 year, newly divorced) and the woman complained of nausea from the smell. I had planned on doing it soon. Now it is on the front burner. Last question. Is it worth getting a later plastic canister and recharging it? It seems like it is easy to find canisters, but not the corrcect mounting hardware. Will the later one sit correctly on my early tank?

Thanks for any help

Dan

Most carb setups use crappy K&N filters that are even worse for containing fuel vapor than they are as filters. You need a closed air box that will trap and contain the vapor so it can be burned. There are a few on the market but they are not cheap. Or you can make one yourself but expect to spend hours and hours fabricating. They can significantly reduce fuel vapor smells AND noise from the carbs.

For my money, I'd rather put the money toward going back to FI, either stock or aftermarket. In fact, that is what I plan to do even after building my own air box. Here's what mine looks like. BTW, even with an enclosed air box, proper carb jetting is important for containing the smell. When my carbs were running rich, they still sunk up the garage. Now that I have the properly tuned, the vapors are tolerable but I think still more than a properly function FI would leak.
