    I just went through your original description of fuel pump mod you did.

    Fuelmiser pump FPE284 is totally different from the original intank one.
    I'm not sure why you had to use Fuelmiser pump FPE284, instead of replacing it with an original one.

    I can't understand why it should leak fuel, unless the O ring seal of the sender unit assembly was damaged badly enough.
    It's not that easy to damage it.

    Another thing you need to consider is that the fuel pressure of the Fuelmiser pump FPE284. It may be too high.
    The AC Delco parts listings had the original pump listed with a photo that was a direct match. Couldn't find a Delco pump available but the Delco book cross referenced the Fuelmiser pump number which was available, so I ordered the fuelmiser pump.
    Didn't even bother enquiring about genuine Nissan parts- pricing is normally calculated on an additional 300% sucker surcharge.
    Didn't expect the O ring to leak for the reasons you mentioned, but all hoses are secure and the fuel leak is coming from the O ring area - Impossible to see with the tank in place in the car.
    "Can't" is a dirty 4 letter word.
    Best way to deal with a "Can't" is to chop off the "t" and brew it in boiled water for a few minutes.
    Sip on the "t", and consider what you've got left to work with

    Did you try Patrolapart? They have very reasonable prices.

    I was able to source the pump from Burson for around $130 on mine. Also available for same price on ebay.

    Your should look the same except the EFI pump is a much higher psi one.

    The Fuelmiser one would've cost you over $150. Way too much fiddling while having to do all the mods to fit it in, IMO.

    Having to lower the tank again is not fun at all. I would look into the possibility of creating a new access hole from the top.
    I'm assuming your is an aftermarket tank, in which the original access hole is no use.

    O ring leakage from the sender unit is a bit of puzzle for me.

    Mine was running okay on both but would shake a bit when idling on petrol. Had a real bad backfire and the air filter housing cracked and the air flow sensor broke We're replacing those but would really like for this to not happen again, how can I avoid this?? Thanks guys!

    Backfire means too lean fuel mixture.
    You need to find out the cause of that, be it fuel starvation due to bad injectors, bad fuel pump, etc or vacuum leaks, etc.
    Vacuum leaks can be located using a spray can like WD40 & spraying into suspected hoses, joints, gaskets, etc.
