    Default Nitrous fuel feed line size?

    About to start installing a plate system on a mates 355 VK. We will be running a dedicated fuel supply for the gas from a small tank in the boot. What pump and line size should we be looking at to support a 300hp shot?

    Any thought's on return style vs dead head fuel regulator's? Are small air pocket's in the fuel / pressure irregularities upon solenoid opening an issue with dead head setups?

    for dedicated n20 fueling a holley blue and 5/16 line should be more than ample. a holley deadhead reg is meant to be one of the most consistant for setups such as these. need to set the fuel pressure with the system armed & flowing but

    We have been looking at the nitrous flow checking tools. $300 is a bit steep. Would we be right to check it with an auto meter 15psi fuel pressure gauge as long as we can make up something to hold the fuel jet while we flow test it?
    I read somewhere that cutting the tapered end off a -3 male fitting then putting the fuel jet in there can work?

    Personally I'd flow it as an assembly into a bucket or something, then set the pressure.

    The Jet itself is only half the story, the lines (size and length), spraybar/nozzle, fittings, solenoid etc should ALL be considered a system in their own right and need to be flowed as such.

    and also when you start running it do small hits first. pull more timing than you need or think you will need to. start on the lowest shot. buy lots of plugs.

    its a lot easier to add timing than it is pistons and rings
