I just installed a Wallbro 400 in-tank. Now I can not get my base fuel pressure below 60psi. If i adjust my afpr it goes up but will not go below 60psi. Any suggestions? I had a wally 250 with -6 feed, stock return with a Areomotive AFPR and it worked perfect. Now that I switched over to the Wally 400 it does not want to go down. Thoughts?
my thoughts...
1) return line too small? (i have seen others running stock return with high-hp applications)
2) afpr needs the other spring inserted (I really doubt this could be it as it was working fine before the 400)
3) tank siphon connector too small (I was told I need to drill out the instilled siphon connector, though I have not tried that)
4) Your thoughts? Anyone else have this problem after a big fuel pump?
