    Hey guys!


    I've been absent from the forums for quite a few months, due to an NA to TT
    conversion gone wrong and being corrected. Will be back with pics and details
    and all that in a couple weeks or so!


    Now to the topic - well... I have a NA 2+2 fuel pump in my Z at the moment.
    I handed the Mech a 2+0 TT fuel pump and they told me I need to get them
    a good condition or new 2+2 TT fuel pump as the 2+0 TT fuel pump don't
    fit? Here's a quote from the Mech.

    "The TT 2+2 fuel pump is different from the 2 seater. The tank's have a
    different depth so the fuel pick up is too low for your tank & the internals
    don't swap over."


    I heard about changing the fuel pick up with the NA one and it should fit or
    something similar.. anyone know what the best COA (course of action) would
    be for my situation??

    If anyone has a good condition 2+2 Fuel pump for TT or wants to swap one for
    a 2+0 TT fuel pump that would be sweet. Kinda urgent, haven't driven my Z
    in like 2 months it's driving me nuts!

    Any help is appreciated guys!
    Looking foward to returning in action to aus300zx really soon.

    The 2+0 pump has a hose that runs down to the pick up sock/filter whereas the 2+2 has the filter/sock attached directly to the bottom of the pump.

    There are ways to swap the parts over however I do NOT recommend this as if the mechanic gets it wrong you could run in to issues with fuel starvation etc.
    Areomotive make a 340LPh pump that will do the job and is easy to install

    Otherwise you COULD (if you trust the mechanic) simply cut the hose that normally runs to the bottom of the tank on the 2+0 pump and fit a filter sock to the end of it and swap the pumps over in the cradles - they DO fit.
    It is the better option to simply buy the correct part number pump though but these are harder to get as the USDM never had the 2+2 TT in the model range so cost will be up there.

    Thanks for the replies guys! Yeah I've been trying desperately to find the OEM 2+2 TT Fuel pump, seems impossible to find and the OEM parts cost over $300 USD.

    mungyz - That link you provided at Z1 Motorsports, so that pump would fit directly to my 2+2?? No need to do modifications to it and stuff??

    :) Glad this thread was able to help someone! I think I may go with a new pump from Z1.
    Thanks mungyz!

    All you need to do is remove the original pump and fit this one to the bracket at the correct hight and orientation, you can attach it to the bracket by using stainless steel hose clamps, then connect the two wires using a couple of crimp connectors.

    The problem with swapping the parts over between the two pumps to make a 2+0 pump in to a 2+2 pump is the clip and pin are a once only design (IE: use only once ever) by forcing the clip off and swapping the fittings over then fitting the clip back on you run the very real risk of the filter sock falling off at a later time.
    This leaves the pump extremely vulnerable to debris getting in there and destroying it, if you trust your mechanic can swap the parts over and ensure the sock can not fall off then all is well.
    I had a customer supply me with a 2+0 pump for a 2+2 car a while ago, I removed the clip and found the hose fitting to be extremely tight on the pump to the point where I was not prepared to go further with the task. Who would pay for it if the pump were to break off its fitting? you may find your own mechanic is not prepared to take the risk either, or he might be happy to and might have a looser fitting than that one I struck.
    (I've removed a couple of others with no trouble)

    Yeah I looked up on this little trick and it sounds risky if something goes wrong.
    I've already decided to upgrade it to an aftermarket fuel pump, plus having something
    new in there.. more peace of mind than a used one :)

    Thanks for all the help man! Problem solved! Looking foward to getting back into the
    Z scene real soon. Much appreciated!
