Upgrading fuel system need recommendations

[bob gonier]

I went with all Aeromotive stuff on my '70 Nova. Their fuel log/return style regulator is awesome and really cleans up the engine compartment. A 2" throttle stop fits underneith nicely. I'm currently running the A1000 pump with great results and have been 9.80's @ 136 mph. After a full season, not even a hiccup.........

Thats a good question Bob. When I got the car, it always had 2 regulators on it, so I left it alone.

Does Aeromotive have routing instructions for plumbing a return system?

Never mind, found it.

Just my opinion- The Filter should always be installed before the Pump.

after talking to Aeromotive their recommendation regarding return line/by pass regulators is unless you are making about 900+ HP , have multiple carbs or running a Nitrous system it is not necessary---one thing that does happen tho is by using a return line you are A) heating the fuel B) aerating the fuel--- because of A&B most cars in their(Aero) opinion do not need a bypass/return line---Because you have the tank in the rear in order to hav ample fuel supply I would run a -12 line to the reg --eliminate the Y and then run a -10 or at the minimum a -8 to each float bowl---as for a pump a Aeromotive/Weldon/Magnafuel will work just fine---- watch the current(Amp) draw on the pump you decide on--- stay away from Barry Grant and some of the Holleys they draw lots of Amps!!!!!

that should be 900 HP OR Nitrous OR multiple carbs not all 3--just ONE of those situations then MAYBE a return/bypass line is called for

Remember one thing ! Weldon is Guaranteed for Life and that means as long as you own it period ! Call Jim Craig @ Weldon and ask Him for a second opinion, You'll be glad you did !
