Right guys, I am trying to figure the best setup for my 20b fueling. I am not going to gk crazy so need something to handle 600bhp flywheel. With a bit of safety margin. Say 650bhp max. I was thinking twin Bosch 310 lph or twin walbro 440lph. However I hear the twin Bosch is very tight to fit in tank. I am also a bit worried about a pump failing causing leaning out which damages the engine. So I am wondering if a single walbro 440lph will do the trick or if there is another pump I can use in tank that will. I really want to keep the intank setup. I think the walbro 440lph I going to be very marginal?
Let me know your thoughts and what you run.

Still running the factory tank?

Yes I am still on the factory tank.. Want to keep with as close to a factory setup as I can.

Reading around some more there is a E85 version of the Walbro I was looking at called the GST450K. this is rated at 455lph and supposed to be good to over 700bhp. up to around 800bhp apparently.

Sounds like it could be the ticket? And possibly consider running a large fuel line form the tank to the engine bay to help a bit more? Not sure what kind of a mission that is?!

Any thoughts or any other options?

A single walbro 450LPH will work perfectly for 500-550rwhp

Run a -8 feed -6 return and you'll be set
