Now, i would like to replace this myself because my mechanic is the kind that doesnt like doing custom stuff (he'll tell me to just get a new Nissan one), and I dont want to pay someone else to do something i could possibly do.
The fuel tank and pump is easy to access (with the boot trim out it is right in front of me) but i want to know how dangerous it would be for me to change it over. I have about 2/3 to 3/4 of a tank left right now....
Is it something that should be left to the experts? I have no trouble doing most mechanical things, but i wouldnt tackle and engine swap alone (if thats any indication of my level of skill)

I fit my own Walbro when i had the RX7. No big job. Red wire to red wire, black to black, bolt it back in, and your away. You will no doubt have to do some stuffing around to try and make it fit 100% as they are a universal pump. All i had to do was cut the bottom rubber mount a little into shape to fit. Oh, and yeah, try to get your fuel level right down.

Dom; Mate just make sure the fuel level is below were the opening to the tank is. and don't smoke mate .hehehehehehe you should find a bracket that the old pump is located on IF the new pump doesn't fit exactly in were the old one came off you will have to hose clamp it in place. IF you have to hose clamp it in place then there is a sock available to put around the pump and under the clamp that is resistant to petrol and will stop any buzzing noise from the pump that WILL drive you mad in the cab . i did mine the first time and never had the sock and i thought all hell was breaking loose in the car. and more so when the fuel level dropped around 1/4 tank . MATE the stereo couldn't go that loud to drown out the noise
LOL, thanks for that guys. I think i will give this a go myself.
Only problem is, my car is not running very well, hence why i have to replace the fuel pump (to start the car i have to open the boot and punch the tank while my gf cranks the ignition, and then once it is started the pump doesnt seem to go at a constant speed, it really sounds like its on its last legs).
So I dont know how to get rid of the rest of the tank (other than parking it out on the street with the fuel lid open and a sign saying "free petrol"). For the first time in my life i wish i didnt have so much in the tank! Haha
Any sydney siders willing to help me remove half a tank are free to put it in their Soarers. I believe it was Optimax last time (either that or Caltex Vortex 98), i alternate depending on which is cheaper
On a side note, it sounds like Walbro are a decent pump then? And $165 is not too much?

Dom; take the fuel feed pipe off the engine or the tank and put it into container. turn the ignition on and pump it out. even if you have to kick the crap out of the tank to keep the pump running. that way you can put the fuel into the GF's car.
With an afternoon of rain my confidence was boosted enough to give this a try. I figured that with the damp air my tank could never explode (yes, i am that naive).
I am going to pick up the Walbro tomorrow so i thought i would have a look to see what i am going to be replacing (incase the Walbro is completely different). 2 nuts holding some metal tubes in (supply and return?) and 6 screws. Then I had to get those metal tubes so they didnt interfere with the removal of the centre bit.
The centre bit was tricky to remove and i got alot of fuel on me trying, but it finally came out. I made my measurements and put it all back together again.
Bridged the fuel pump relay so I could pre-start the pump (punch the tank) before trying to crank the engine and its all working (albeit still with the old pump). All up it only took 1hr
SO now comes my questions. Some research seems to indicate that Walbro will be quite a noisy pump. Is that true? I also read that the 255LPH pump will be too much for a stock FPR???
Thanks shaun... I cant wait to finish it now to try it out! I see that you can get a Sard fuel pressure regulator on Ebay for $134 so if it is too much i will just get that (LOL, Walbro fuel pump, Sard FPR, i'm considering Splitfire coilpacks and aftermarket injectors to cure a misfire - yet i have no desire to make the car faster... Aftermarket parts are cheaper than OEM on this car!)
As many problems as this nissan is giving me, it just makes me more determined to get it right in the end...
LOL I had to doublecheck even though i had one in my hands 2 weeks ago. Yes they are top feed injectors. One of them had burnt the tip out so i had to find a replacement. $150 to replace it with one that was "similar" and then my Mechanic tells me that another may be bad as well (was stuck open), but after cleaning it seemed ok
Now one week later it is sputtering at idle as soon as it gets to operating temperature (seems to rev fine though?). I'm considering replacing all of them with aftermarket if i can work out what other cars share the same injectors
On another note, i got the fuel pump in without any problems. Turns out i didnt need any hose clamps at all! It was virtually a perfect fit, the rubber grommet at the bottom was just right, and it was around the same height as the OEM pump. With no cable ties it is almost completely silent, the noise is drowned out by the aircon fan...
And it doesnt seem to be surging so I dont think i need an aftermarket FPR just yet...
