Hey guys,
As the title says, is there a higher flowing unit that I can basically just throw in, in place of the in tank Walbro 255? The car is an RX7 with LSX swap but the walbro 255 that I am using now came out of a 1998 Trans Am WS6.

Thanks!

I just bout the Walbro 400 LPH unit part number F90000262.

I found this and figured it will fit in mine...

It'll fit, not sure what you have for a regulator but if it's stock it'll overpower it and you'll see like 80 psi rail psi at idle

Im running the stock 1999-2004 Corvette fuel filter with built in regulator. So that mean I need an afermarket Fuel Pressure Regulator? Thanks!

Just for anyone who might be searching later on, the Aeromotive Stealth 340 bolts right up. It's the same physical size and is MUCH quieter than the Walbro. It's what I've got in my FC currently, replacing the old Walbro 255.

make sure all wiring and connectors are up to the job too, all those Walbro style pumps larger than 255 draw huge amounts of current

What part number?

UOP

Years ago I modified my stock hanger to work with a Walbro 255 intended for a fox body mustang, so the one in my car isn't the same part number. However, according to this document from Aeromotive the correct part number is 11141.
