Dellortofuel pump vs 12v sip

whats better for me? ive got a 28mm carb and 2 fuel tanks the normal and legshield. ive got no battery how well do the 12v ones work with ac? what better suits my aplication?

Hi,

 

I got one sip electrical. It was a pain in the arse to get it working! and also it was very noisy. I didn't like it at all. Finally I got a dellorto one and I am very happy.

ive got 2 fuel tanks though using a mechanical pump may be alot of hassle to put return lines in both tanks. i might just run the electric pump from the legshield tank because my stock tank works fine with the 28mm carb and no pump.
