4age Ke70/Ae71 Fuel Setups

[pauliee]

hey there guys,

currently most of the way through my smallport 4age conversion in my ae71.

Just curious how you guys have set up your fueling process with the stock fuel tube thing (with banjo fittings at either end)



(this thing^^)

Currently, I'm running the pretty standard setup that consists of JDM 86 Fuel Tank, ae71 lines, to which at this stage I have worked out i can run a Ryco Z412 (8mm Barb inlet, M12x1.25outlet) filter, which should allow me to hook into the stock smallport (hopefully).

Whilst this should i work, im interested to know how others have gone about feeding fuel to the rail.

any photos would be great!

Cheers in advance,

Paul

The neatest way is to buy yourself a small port 4age petrol filter and mount it in the bay. You'll also need a section of pipe with the fitting to screw into the bottom of the filter. I'm sure places like pirtek etc. can do them as well or you can buy a jdm fuel supply line. I got mine off the donner car I got the engine from and mated it up with a small section of efi hose.

Can grab bosch filters from ebay...


You'll also need a banjo bolt with a hole in the middle of it to bolt the fuel line to the top of the filter.

I hope that helps, some people cut the banjo fitting off and connect the line straight into the existing ke70 hoses.

hey there, cheers for the reply matt..

Well after playing around with a few ideas, i ended up cutting that fitting off, using the banjo with some new efi hosing. Also used fuel filter from a 300zx.

Came up nice and clean, might not be a factory setup, but should do the job..

It works, just make sure you got efi clamps to minimise wear on the hose itself. Its one of those things where using the banjo is neat, but ultimately won't make a huge difference.

aww rookie error, used normal hose clamps. Will change it up though.

heres my setup anyways, constructive criticism always welcome

looks pretty much the same as my setup, i think i've got an s13 setup in mine. i have mine mounted vertically though, when i had it mounted horizontally it would feel like it surged for time to time.
you going to run cold start? i'd say get the hooked up next before you go much further

[pauliee]

oh really? i guess ill see how i go with it horizontal, and i'll swap it around if i get similar surging issues.

and negatory for the cold star, the wax pellet idle is fuarkked, so Golberg suggested best option was to block it off completely.

you can also buy banjo to barb/pushlock fittings from places like Enzed or Pitek, which mean you can make a much more solid connection.
Ive done the old "chop the crimped stock fuel line" trick to make a hose clamp connection, and it ended up leaking.

Get the banjo to barb fittings. They are cheap, and work reliably, and give you a wide range of options for how you want to connec the rest of your fuel system.

dont mean to thread steal

but im planning on doing a gte in my ae71 and was wondering if the ar71 fuel lines would flow enough for a basic set up say 180 to 220kw???

the bracket that holds an ignition coil is pretty much perfect for holding a 300zx filter if anyone's interested.
