Fuel cut off relay

[Rara72]

I am going to be fitting a electric fuel pump to my 1.9 wbx and a bit confused about what relay to use.

I like the look of the CSP one https://www.csp-shop.com/en/electric/sa ... 8015b.html    as it says it will switch pump on for 2 secs at ignition switch on  to prime carb and then switch off until Engine is running.

Problem is everywhere is out of stock.

 Is there another relay that will perform the same as this?
