Just wondering is there any other lines I need to run off the inbuilt Ve pump in my drop tank
or just get some AN fittings and hose to attach to the one main line to the ls3?


Also what are the best AN fittings for high pressure fitment wise and quality, speedflow, Aeroflow, ect.

Are these a regulated MRA like a VZ? The VZ you go out of the MRA to the filter, then the outlet of the filter has a T piece that returns to the MRA on one side and into the fuel line to the engine on the other. The MRA also has a breather port on it that goes to the canister.

Not sure to be honest just trying to clarification on it all as I know stuff all about fuel systems.

I asked Brown Davis sales and they told me

“Hi Nathan
That fitting is the factory fuel delivery pick up you can block it off or use it as fuel return if required “

Still didn’t help me though.
I just assumed you get the ve pump installed in the tank and it does everything so you just connect it into the main fuel line.

I’m not sure about VE, but I’m pretty sure they are regulated at the MRA. Not sure if they need the recycle like the VZ around the fuel filter. They might just deadhead to the engine.

I'm not an expert, but I think they have the regulator as part of the pump and they are return less. This would mean you just need the one fuel line going forward, plus any breather lines for the charcoal canister if you are running one.

VZ is regulated too, it’s the MRA I put in my HK GTS tank. But it does have a fuel return from the engine side of the fuel filter which sits just in front of the tank. Not sure why it’s there, and don’t know if a VE MRA needs it. I didn’t use a VE MRA as it’s too short tor the HK tank.
