created the thread low fuel pressure at idle
" I have a 335 with jb4 and cobb backend flash with the walbro 455lph. I installed this using Terrys diy with 225psi e85 rated lines and my lpfp only holds 50psi at idle. When i get in the gas it just drops pressure runs lean and misfires. Any ideas what this could be? "
