Just bought a set similar to #6 and it worked well on the fuel filter.

I've successfully used #5 on my fuel filter a few times - but can't get it to work on my fuel pump connectors

Will be trying out #2 or #4 tonight

I have 2 sets of pic #2, I use them all the time. I used to have some of the metal scissor style ones, but they are sometimes unwieldy IMO.
