...I had a 'WalBro' pump fail on Me, once, in a different Car. It was the Aluminum Body 'Recipricating' Style. The Rubber Diaphram had ruptured. Make sure You have the Fuel Filter AFTER the Pump and NOT BEFORE!!
'Filter Before the Pump'; makes it more Difficult for Atmospheric Pressure to FEED the pump! The Pump does NOT creat a Vacuum, it merely Provides a 'Void' and Creats a 'FLOW'!! For those who Never took a Hydraulics Course!
'Pressure' is created when we start to Restrict that Flow. That is why a 'Layman' thinks His Pump is Not working,(and I'am NOT speaking of THIS Case) when they put a Pressure Gauge on the Output of a Working Pump, and the Gauge reads '0' ZERO Pounds!! Because the Flow is Not Restricted!
By the way... Your Fuel Tank is VENTED, Right!
NOW, in the Pantera, I use a Holley Electric with a Regulater.
