fuel pressure and boost

[Texas gn]

Would someone reminded me of what kind of fuel pressure I am looking for at 20pounds of boost? I am seeing roughy 62-65 psi. Thanks

if you are running at 43psi FPR ( Vac line off ) then should be 63 psi so you are right in the ballpark! 1 psi boost should be 1 psi Fuel press rise. ( 1:1 ratio )

Thank you. I am planning on kick the boost up to 26 psi, so i might need a little more pump. My walbro 255LPH might be getting tired.

how long has the 255 been in there? i just put mine in a couple of weeks ago with the hot w. I'm still at the 13-14 psi stock boost. I really want to baseline what i have before i touch it!

Do yourself a favor and dump the Walbro and go with the DW300 you won't be disappointed. Just compare the two.
