Fuel System

[WHITER33GTS-T]

here is mine im my 33. its not pretty but does the job.

Im running 2 044 pumps and 2 filters. And runing 2X 3/8 fuel lines one to each end of the rail

[Gts-t]

Yeah, i think theyre 3/8 in diameter or something like that. They couldnt be in a better place really. Silly to run braid or any other solid line under the car if these are unused.

Whats wrong with just using the standard fuel lines under the car? Thats what i did, my setup is the blue skyline in the first post of this thread.

Can you remember the exact fittings you used to hook the braided lines up to the stock hard lines?

haha yeah i know i have that link bookmarked i was just wondering if he could remember an exact speedflow fitting / part number he used

yeah hose clams lol, i figured if it was ok for standard then it should be ok now. The braided lines are only for looks really i could have just used fuel hose.

Ok well the fuel set-up seems to be almost there, now I'm after ideas to hide the ugly wiring for the injectors, any pictures or ideas?

Black flexible plastic conduit, available at auto sparky / hop up shops.

[PSI Parts]

That was my first thought, however I find that most of the time it looks really messy or disorganised. I'm thinking of running them underneath the fuel rail through cable holders (similar to what's used for computer cables or home entertainment cables) so that I don't have zip ties and plastic conduit going everywhere.

well finally got around to getting some new update pictures of my fuel system

Some very serious filtration going on there.

Are you running one tank for methanol/race fuel and the other tank for normal duties? As it looks like you have a distribution block that links to the fuel lines that run underneath the car?

u guessed it!

the sard surge tank is connected to the standard fuel tank which will be used for ur normal every day 98 octane

the fuel cell will be used for race fuel

the car is setup so it can swap between different fuel's via a switch inside the cabin

we are able to do this because the haltech E11v2 allows us to hold more then one tune map

so with a flick of a switch we can go from street mode to race mode

the wiring involved thats going into a setup like this is just mind blowing

the fuel cell is a custom item which we blue printed from the sard surge tank

we bought the sard surge tank from hi octane and copied its design and built our fuel cell from it

so not only is it a fuel cell its also a surge tank all in 1

the filler cap and lid are all CNC machined from billet

we will also be making our own sard surge tank copy's which we will have on the market for less then geniune sard items and they will perform just as good

V8 supercar. 2 external pumps + 4 internal pumps in each corner of the tank.

Does anyone know who makes these?

I've had a look through earls, russel and speedflow catalogues but have yet to find them.

[GeeTR]

Each of the big three motorsport connection manufactures make Y blocks I think.

If you want fancy ones like that, MagnaFuel do them in poiple

Cheers, Martin from Earls beat you to it though haha.

I want them to be parallel as I'm using them for twin Earls Fuel Filters, lets just hope they fit.

hmmm..bumping an old thread

Buuuuuttt

What are you guys using to switch the pumps on and off relay wise? I assume you just splice the factory wires to trigger the relay?

[shanef]

Fuel system i recently did for a mates 33gtr im building.

For the fuel pump wiring, i used 2 30amp fused relays, 1 for each pump. Power is connected straight to the battery, and the trigger for the relays is spliced into the factory harness, its the wire that goes down into the fuel tank, its a switched 12v that powers on when u flick the key, easy to find with a multi.

thanks mate, that must be a serious GTR if it needs an A1000 Pump
