Help wiring a lift pump and fuel pump

I will be fitting an external swirl pot.
This will need a low pressure pump and a high pressure pump.
Now I am all clued up on the plumbing, but how do you safely wire in two pumps?
A diagram would be cool thanks

I haven't a clue - but don't forget to keep the Webasto before any pumps (in case you need reminding

)

Text me tomorrow chap and will get a wiring diagram that i usually use when putting leccy pumps on Aircooled.
Twin relay that is fed from alternator so cuts fuel in event of engine stopping for safety sake and doesnt just pump non stop. Low pressure pump wont cause any major issues as if fed from ignition live , the swirl pot will stick excess fuel into tank but better safe than sorry.
HP pump is fed off DJ loom.
TBH everyone i know has ran GTis without a LP lift pump with no issues if using a Mk2 pump/swirl pot.
Make sense?

I did question the need for lift pump as the pot is at tank height...and I'll not be racing owt
I'll try without first perhaps, that'll keep the webasto happy as oldie says
