Im putting an s475 on my 2000 ecsb 4x4 and need some fuel ideas. My camaro i had i did twin 255s and one was boost activated via my meth switch. Any reason i couldnt do the same on the truck?

 

I would just drop a walbro 450 in your stock bucket, a single 450 will support that on gas

 

Most run the 450. I run dual 255s.

 

The 450 will over run the stock regulator though wont it?

 

yes, it will

 

yup you'll need a upgraded FPR the walbro 400 overpowered mine

 

I'm going the 450 route. Extra work now but will support any of my future goals. Just add a 255 on a switch and i'd be set forever. I'm building for 93 octane & meth.

 

I would do a dual aem 320L. For sure enough to support everything you need. Affordable and even if you switch to E85 you are good to go. You could even do a corvette filter setup and just run a hobbs switch setup to activate when you hit boost.

 

Im running meth also so i dont need a huge pump. Talked to racetronix and their drop in modules look nice. The 255lph version i dont think will cut it but they have a 340lph option now that retains the jet pump. Anyone have any fuel starvation issues when hacking the bucket with a 450 or sual 255s?

 

I wait until the low level fuel light to come on before i get gas. Been doing that for 2-3years without a single issue. My bucket is uncut.
