Ok u will need relays as the current drain on 2 pumps is a lot.

you are using the same pumps as i ,but i do not have dash switching.

using black/red fuel pump + split into two and then connect to two quality switches of your choice, then the other side of switches go to two 40 amp relays labeled no 86 ,u will then need battery feed straight form batt to spade labeled no 30 ,connect earth to each relay no 85 , and then the last spade terminals are for fuel pump +no 87.

it is late so i will check numbers for relays tomorrow.

unless someone else can clarifiy ?
