Good morning all,
I'm looking to perform a fuel system upgrade to rectify issues related to engine compartment heat and E10 fuel (non-eth. not avail in Mass).
I've dug into all the info I could find on this subject, and looking for feedback on my current plan.
This is for a moderately built street 440 currently with a Carter high volume mechanical pump feeding dual Edelbrock AVS2 carb. with 5/16" line, no regulation, no vapor separation filter and no return line. The fuel pressure is a consistent 6 PSI (boarder line with these carbs), and engine runs strong and consistent with air temps below 85*F. Any higher and we have a problem!
My off-season upgrade plan is to replace the sending unit with a Spectra 3/8" (I'm aware of the resistance issue) reworked with a 3/8" return line and a Tank Meter Match. Mechanical pump will be removed and replaced with a Carter P4395 electric. After pump 40 micron filter at pump for serviceability (maybe 100 micron before), 3/8" supply/return lines routed along frame (insulated) up behind alt brackets like factory to fuel log, then pressure gauge, then Holley Bypass Regulator (set to 5.5PSI), returned via 3/8" to tank.
Attached is a diagram.
Anyone see an issue with components selected or routing issues?
Thank in advance!!!
