Get every dollar out of the stock one.

its not worth taking the risk cos with this view, it might srsly end up costing you more dollars than you bargained for. If your going to do at some point, why not just do it now, cos at 280 rwhp, you'd be pretty much close to maxing it up. Sometimes you cant even notice have much it is leaning out. i'd say just change it, before you do long term damage

As rednecks would say 'don'ts fix it till it's brokes'

But seriously should be fine, and you don't want to put fuel pump in unless you really have to... It's a stinky c**t of job.

Buy a fuel pressure gauge only $69 (defi style) from just jap for fuel pump insurance + you can rice your cabin up more.

I reckon change it. Its not worth you taking the risk till it dies, it will leave you strandard in the middle of no where.

If you have the cash just buy it, there is no harm in changing it. It may last you another year, or maybe it will last another day. Who's to say when it will go?

At least with a new one, you will know its got a long life a head of it, and its not going to clonk out any time soon.

If your planning on getting more power out of it, why not upgrade it. The stock one didnt cost you anything anyways..

You could pick up a replacement pump, like a BOSCH 040 cheap enough.

Buy a fuel pressure gauge only $69 (defi style)...

But $70 is like half the price of a fuel pump. Later on if he buys another fuel pump, when it does die, it will cost him more in the long run. Might as well spend the cash and upgrade now..

Just my thoughts!.. :D

Where are these $140 fuel pumps you speak of... my genuine bosch cost $220 delivered. A fuel pressure gauge is a good idea all the same, as if fuel pressure drops the afr's lean out and cause damage.

Many cheap after market fuel pumps break or seize shortly after installation due to poor installation, factory faults with pumps, and especailly with 040's the bottom filter screen sucks up crap and reduces possible flow which burns out the pump.

By your reasoning you should sell your r32 and get a new car because it could die at any time.

keep the stock fuel pump, its still working, no reason to change it and spend money now rather than later.

If it dies in the future, change it then. It'll take you 2 hours max, and usually they slowly die rather than just stopping working all of a sudden, so you should have plenty on notice before it goes.

i say stick with your stock pump untill it starts to die, or you decide to do more upgrading. atleast you know it is working. you may get a new pump and it may be faulty straight out of the box, so you would be driving around thinking everything is fine and then end up causing more damage. if you do get a new pump installed i would put it back on the dyno to see if the mixtures have been affected. ucd15r33 put his car on the dyno 2 days after a new fuel pump and the mixtures went from in the 13's to low 10's, so upgrading his pump was a good thing. but if your pump is good and the new one is dodgy it could go the other way.

I didnt say $70 was half the price of a fuel pump, I said its like half he price. Although I have bought a original BOSCH 040 new in the past for $160, which for arguments sake is almost double $70..

You could spend $180 and get a BOSCH 040 brand new, theres one on calaisturbo at the moment. Original BOSCH too, with receipt.

All I was saying was if your after a bit more reliability, and peace of mind you might as well change it. Its a matter of $200 max and about 2 hours work. He obviously has some concerns, hence this thread?

The stock fuel pump would be a least what, 14 years old by now?

Not even going to justify that with an answer.

But according to your signature you seemed to have recently upgraded to GTR fuel pump from standard?

Any reason for that, since your car is only making 155RWKW, which is plenty for the standard fuel pump to handle..

Just curoius.

first of all what car is it, i may have missed something, if it is a GTR then it should be fine, however if not i would change it, yes you have had the car tuned and all was good but i can tell you the harder you push the pump the faster they fail and you wont notice it leaning out all that much until it is too late, changing a fuel pump is an easy job especially in a nissan most local mechanic will only charge you around $50-80 or you can do it your self in a half hour. the cost of a new pump is not much and is good insurance

Yeah fair enough, I guess I was just trying to make a point that you can't always go around fixing things just because they might break in the future.

My fuel pump (r32 gtst) lasted 14 years and 175,000kms. I discovered my car was running lean so i replaced it with a GTR pump.

So IMHO if you know your pump is providing enough fuel, its not worth replacing it.

I guess if you want the extra peace of mind, upgrade it. But make sure you get it dynoed after to ensure the new pump is operating as expected.

When my stock pump started to die it went from nice solid afr's to running dangerously lean within 6months.

If its old, high km's and showing that its a little lazy.. Replace it; not worth the ringlands.

Your tuner will know what you pump is good for and if its lazy or not.

      Yeah, my moulds and seals are 32 years old now. I think I will continue to not use a pressure washer on it.

      I hear the old "I'd never use a pressure washer on my motorbike" BS in the dirtbike community too.  The only people that have had a problem from using a pressure washer on anything are the people that aren't using them properly.  If you hold the wand any more than 45 cms away from pretty much anything (radiators, wiring connectors, paint, etc) you aren't going to cause any damage.  We've had detailers wreck moulds and seals on cars at work before and the only reason why is they held the pressure washer too close and on the one spot for too long.  If you have 5% more brain power than a detailer then you know not to not do that and you'll never have a problem.

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.
