HI There,

If a fuel pump is on it's last legs what are some tell tail signs that it needs replacing?

Could one be that when I turn the boost up (to say 11 psi) and floor it a sudden fuel cut comes in.... like all power stops, cause when I turn the boost down to 9psi it works fine...

Also when I touch the accelerator lightly I can here a high pitch noise from the back of the car.. (and also when cruising at 60 I can also here it then).

So that said, if it is my fuel pump should I just replace the unit with a new factory Nissan one or buy a second hand GTR or what?? ( I have an R33 gts-t with FMIC, Air, boost - 163 rwkw's)

Are they just a simple replacement or do they need a lot of work to get in?

Thanks for the advice.

Rob

Welcome to the world of boost cut - above 12psi and your computer says I've had enough.

You can buy a defender to stop this happening, but if you are thinking about upgrading the ecu or fitting a SAFC(I think), you wont have to worry any more.

As to what to do if you have to replace your fuel pump (which I dont believe you do yet) that will depend on what your future hp goals are

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
