Im at the point in my build where I have to run the fuel lines. The original Regal set up is a three line system with an in-tank pump. A fuel line, a return line, and a vent. What has everyone been doing with these lines on a carbed 455 transplant? Also what size line can I run to accommodate 600 or so horse power on a carbed 455? Thanks....
Im running a rear mounted electric pump with 1/2" hard line run inside the R frame rail to a reg mounted 6" off the firewall then split into 2 3/8 lines to the Holley.
... 1/2-inch braided stainless steel single line from electric Carter fuel pump (inline filter) out back to TA Street-strip mechanical fuel pump on block (inline filter #2) to Holley 850 DP. :3gears:
Are either of you running a return line from the regulator back to the fuel tank? I have the body of my car off the frame right now so I'm wondering if its worth doing a return line too.....
I have 1/2 line from the tank to a regulator, then 3/8 to the carb fuel lines (Holley 800 D/P). Used a 3/8 return line since it will be mostly street driven and was advised by some that it puts less stress on the elec. pump. for longer, continous use.
I'm running a Robbmac 1/2" pickup with 1/2" braided stainless steel line through an inline filter to a JW mechanical fuel pump with 1/2" braided line to an 850 DP Holley. No need for an electric fuel pump with this set up, and no return line. This is working very well for a JW 470 with close to 600 HP. Roger
I am in the process of upgrading my system i have a complete mallory 140 set up with a new mallory fuel filter i will be selling very soon if interested.
I have a jw 470 being built right now. Somewhere down the line I may supercharge so I'm thinking up a fuel setup I can expand if necessary. I am heavily leaning towards an aero motive set up with 5/8 feed and 1/2 inch return with a fuel cel and an a1000 pump. ---------- Post added at 04:33 PM ---------- Previous post was at 04:31 PM ---------- i appreciate the offer but not what I'm looking for, thanks though...
Run #10 line front to back. You can use a holley blue or black for now dependingon your application. Once you get a supercharger you can upgrade fuel pumps and line will already be ran. Are you goin fuel injection? A1000 were designed for FI from what I understand not sure you will get pressure low enough for a carbs setup.
Should be nice efi. If your not stuck in using a fuel cell I would recommend using a GN tank and sending unit. With the technology now you could run a single 430 or dual 255 intank setup that would easily feed what you want. Would probably be quieter than than the aeromotive give you a more stock appearing and keep all your trunk.
Ive got a -6 line using parker push-loc to the front and a -8 line as a return ( also push loc ) -- no issues ever or running out of fuel... As a side note Im just removed an EZ EFI setup off a vehicle and am selling it for $750 if you're interested -- will come with everything that the base kit includes with the following exceptions --- 1. the wiring harness ( recommend you purchase a new one so you don't get a hacked up version ( $188 from FAST )) and 2. Ill include a MALLORY return style FI pressure regulator -- you will of course have to also provide a pump that can provide the required volume and pressures...PM if you're interested.
Im going with the ez efi 2.0, Im assuming this is the original system, if so Ill pass, thanks though...
