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?

I think I ended up getting mine off of amazon or something as my local stores did not have it in stock. Last edited by Jeller; 05-05-2013 at 06:32 AM.. |

Probably the venturi line or you could have a kink in the line coming of the pump. My venturi line came of and my pressure sat at 32 and lowerd under wot. Also make sure that the fuel flow goes straight through T fitting. Good luck with it.
