Running two fuel pumps

 hi guys and girls I'm just wondering about if it's possible for me to run my facet pick up pump and Bosch 044 main pump and the same wire circuit. I have got new wiring so should cope. But just wondering about the fuel pump fuse it's a 15amp at the moment and thinking if I should up the amp to a 20amp or more?   so basically I want to run my pickup pump and loop this to my main pump and just up the amp of the fuse is this possible???
