What manifolds are used for the Dellorto conversion? I have 36 & 38 carbs, just wondering what maifolds can be used.
Source for Malossi manifolds?
Maybe Alazzurra ones could be used.

Yes, manifolds (and carbs) from a Pantah are good, and the aftermarket source is Malossi. The Malossi ones are finished nicer, but dimensionally they look the same. They are sometimes refered to as 'short manifolds', compared to the stock ones that are really long. The rubber connector boots are common to most of the ducatis through the 90's that had carbs. The front and back cylinder manifolds have different angles. If you get a set from a bevel head, they will both be the same and one of your carbs will sit at a very odd angle. I know this because I have a set, and am looking for one more to make a set to fit my Sport. You can check with the guys at BevelHeaven to see if they can still get the Malossi setup.

Dellortos have a limit to the angle that they operate, but its pretty generous. The closer you get the two to level, or matching eachother, the better off you will be. The front head needs more of a sweep than the back head will.

Is the fuel pump still required?

No, the fuel pump is not required, but it doesn't hurt either. I have the Sport, and have to run the fuel pump because of the way the lines and pickup are welded into the tank. I don't know how the Paso tank is configured. If you run the pump, make sure you have a T in the fuel line that goes back up to the return line on your tank. One of the stubs on the bottom of your tank is overflow, the other is the return. Also make sure that there is no restrictor in the return line, as some people have reported having. Blow through all the lines to make sure they are all clear.

Also, make sure that your vent tube is not crushed or blocked. That happened to me and it took a long time to figure it out. Bike ran great for about 15 minutes, then it would run on one cylinder. I guess my gas cap fits like it should.
