    Chill out buddy, just saying, not having a go or anything.  They are a great pump, gerotor style so nice and quiet, good quality.  There are a few good fuel guys in Oz, each has their own preferences, all good :good:

    Yeah i agree with about 1000hp

    Yanks have a weird way of rating pumps for hp

    Almost like they free flow them and go will at no pressure it flows X amount of litres and that will support 1500hp so we will say that

    But really only see that power at 20-30psi boost and that gives a 65-80 psi fuel pressure so has a effect on fuel pressure

    I had paid for that serge you have but then i changed my mind and asked and changed order to a sp1200

    Love my aftermarket industries serge tank

    Stunning the build and design quality

    The fuelab pumps are the same

    There is just no way a single prodigy pump could supply 1800hp

    And stuff fuelab anyway complete puss

    :cry:

    Exactly.

    Its been quite a humbling experience actually getting  a grasp around what a proper fuel system to suit your needs is required…. its been alot more involved than the supercharger itself and everyone has there own opinions on how to do it, atleast i know I wont be blowing a motor from a lack of fuel after all of this. To the OP best advice i can give you is get intouch with someone in the know and let them design something for you and go from there, i had people telling me a single walbro 460  no surge would be fine for my application and i got laughed at when i passed that on. Talk to the guys in the know buddy :)

    Thats the base of what julian was telling me, no way can that pump supply a 1500hp motor in the real world.

    +1 for there quality its incredible, billet surge tank mmmmmmm  :yes:

     

    Why did you change to the Sp1200? did you want the tank in your boot and not undercar?

    good advice bloke,theres a bit to it,especially  if car see corners or gets turned inside out.

    good for a bit of a chin wag

    got a laugh out of reactions too,i gotta sit back for a while after i type stuff,,haha

    also later stuff with them cradles that drop in look good.

    anyone measured one of them walbro’s,diameter,VS got a 60mm hole in tank,i’m trying to keep a fairly stock look,for the man really,haha

    But now i see people bolting them up under parcel tray witch would work great

     

    I also have a walbro 460 in tank

     

    Im using a factory vs fuel sender

     

    I just cut about 5mm of the pipe and it fitted between where the factory pumo sits and then i just welded a stainless hose clamp and that holds it in place

     

    I also got some fuel tank fittings and mill spec wiring from efi hard ware and all works a treat

    If noone has one measured i can do it for you when mine shows up (just delayed atm because AI cant post due to the weather in NSW). Im sure they will fit – they need a couple mods to fit but they do work in there no worries

    Fuel pump flow rates aren’t exact, depends on the viscosity of fluid they are tested with and then what is used in real world. Fuel pump ‘hp ratings’ are a very very rough figure.

     

    The 1800 holley pump is rated at 156GPH@43psi, 140GPH@60psi and then would rapidly drop off after that. Its listed on their website. Then you have to account for pressure drop in the amount of line to the injector and the number of fittings.

    Still reckon this is the best solution, all contained in the tank itself, no hoses running all over the place, easy as to work on, dont lose any boot space :)

    here is what I did to myn

    it’s a walbro 460 custom attached to the factory sender

    must note in not using a factory tank, myn is a custom made alloy tank that just has a heap of baffles in it

    It just and I mean just fits into my tank witch has the same size hole as a factory tank as I took the measurment and had that piece laser cut

     

    i had had to cut 5mm off the pipe where hose connects to and that made it fit perfectly, had to cut the bottom rubber to fit the walbro pump nicer and used submersible hose

    Hi buddy

     

    i made that table a couple years back, I also made the cupboard in the back ground and heaps of other stuff as well

     

    and no don’t live on a boat and yes it’s cork floors and are great, They don’t hurt your feet, I love on the beach so carpet is no good at all and cork is awesome

     

    as for the pump yeah it’s a good idea for people running decent power and don’t want a serge tank but It might suck the swirl pot dry not sure

    I used 2 fuel tank bulk head fittings and run them through the tank
