I recently ordered individual ITG air cleaners/filters and air horns from Motorsport Auto for the SU carbs on my '71.  This is to replace the stock air cleaner with integral air horns.  This is what I ordered:

Anyone have experience with these?  I have a couple of questions:

1)     There is not enough room between the end of the new air horns and the inner fender to fit the air cleaner foam element into place against the backing plate, so it appears that I will have to remove the carburetors from the intake manifold, attach the air cleaner backing plates and air horns to the carburetors, attach the foam element to the backing plates, then reattach the carbs to the manifold.  Is that correct?

2)     On the factory air cleaner backing plate, there are 2 nipples to which attach hoses from the float bowl fuel overflows so gas does not fall down onto the exhaust manifold/headers.  The ITG backing plates have no such nipples.  I thought about running hoses to an overflow canister / container attached to the inner fender, but that's not very elegant.  Any suggestions from someone who has or is using these air cleaners?  Thanks.

What happens to the hose that vents from the valve cover? If you moved it to overflow can you tap into that? Or is it all atmosphere?
