I am removing the air pump from my 79 SC. I've removed the network of injectors into the exhaust heads but I can't figure out how to remove this piece from the underside of the engine. It is held in place by two large nuts at the back of the engine just under the top of the engine compartment/the air pump.
Any tips to loosen these nuts so that I can remove the tube that delivered air to all of the exhaust ports?
