Fuel Pump options

Hey guys, just some questions for you as I’m looking to get a new pump for my SR when i put it in. I know the Walbro pump is probably the most popular. But ISIS makes one and Aeromotive, AEM, and Airtex aswell.

Price wise they are all pretty close, just wondering if anyone has any experience with them.

Also, does anyone know the part number for the Walbro kit? Keep getting different numbers

the walbro 400’s can flow handle some serious hp on pump gas

I’ve seen 500-600 whp on just a single pump
