I got a plaz surge 2nd hand, a 044 was about the same price as yours, made my own harness / relay setup and used ethanol rated fuel line ( non braid ) , all from green lane speed shop in Penrose, Auckland.
You might want to consider a non return valve too, post pump.
I didnt use a filter pre or post pump, figured the intank and chassis rail filter was enough, no problems so far with around 40,000kms on it.
I'd pm ralph and jet regards the pierberg pumps too before pulling the trigger on a 044- noisy mofo things, would not bang again.
