My 040 in tank pump has been noisier than normal for the last month or so. Thought it was my imagination being overly sensitive to all the sounds my car makes (Skyline paranoia) and Leesh telling me she can't hear it.

So I took off from the lights today showing an HSV how it's done and hit a brick wall on high boost in second; thought I'd done a cooler hose so putted off boost to my destination and popped the bonnet. All hoses secure no sign of a break in. Fuel pump quite noisy on idle now, and especially noisy when the variable voltage kicks in with throttle on...Leesh can hear so it's not my imagination.

After 5 years of faithful service, is the 040 dying a slow death? Now feels like I'm driving a ticking time bomb. Gonna buy another one but fearing there may be another issue at hand. Is it possible fuel lines / filter / rail have a blockage and the pump is noisier because it's trying to suck a softball through a straw?

Started getting noiser pre-98 octane switch, but now feeling like the switch has aggravated it further...possibly because I ran the tank pretty dry or the 98 has caused some crap to unclog and re clog somewhere?

Sincerely,

Birds

inb4 get a different pump - if I'm buying a new pump another 040 is going in! 5 years is nothing to sneeze at and 2 of those with ethanol when it's not even sposed to be compatible with it.

get walbro.....im on my 3rd in 5 years...at least it quick to change now.

I swore I'd never do another 33 in tank pump again after the first installation...it's a nightmare for anyone without spaghetti arms. But here I am...

first time had to modify the loom for the pump as well for the walbro, and think the s14 tank as bad as the R33 one.

could be worse, to do the one on my ute you have to remove the tray, or the whole diff assembly and then the tank.

040s get f**king loud when they start dying

Source: killed multiple

Get a 460 pump and for gods sake redo all the wiring in one hit

Yes it is annoying

But better than doing it 9 times and WAY better than having your car die because you have a powerFC that wont save your engine by cutting all your fuel when you hit 18:1 AFR on 20psi.

Appreciate the concern but I don't see it popping my engine anytime soon while I'm driving around off boost. Worst case I end up stranded and needing a tow. It already leaned out on me today on boost, that might have been a lucky experience but now that I know it's on the way out I'm driving cautiously. That this one lasted 5 years is a good enough interval for me to suggest I installed the first pump properly with good wiring and in a good position - plenty of people kill walbros/Nismos/bosches in shorter time; replacing fuel pumps is just a fact of life for modified cars and in-tank pumps that cop abuse from tracking etc. Everyone replaces them. The 040 is cheap and to a degree it'll be take out and drop in cause the hose lengths are already cut for it and wires soldered to correct terminal size. Fk doing all that again for another pump type. Tell you what if this next one goes I'll get a 460 :P

Also gonna keep the variable voltage setup - think this may be a reason for longevity of the pump as a lot of the time it was cruising away on low voltage mode. Also keeps it quiet.

I just find it suprising it supports the power you're making, i.e 270ish on E85. Would have thought itd be close to running out.

If it meets your needs its worth doing it again, but the 040 certainly certainly clogs up more than your average bear.

Mine was doing 335kw on E85 with still room for more.

Also lol Birds you cannot complain about a 33 GTST Fuel Pump fitting. The only thing easier is a 32. Try fitting a pump in a 34 GTR!

I'm surprised they're not more popular than they are (and they are popular). See people doing lift pumps and twin 044 setups in street cars lol?

A single 040 can flow 600hp+...shitloads of headroom on this pump and at $160 why bother with anything else!

Interestingly Just Jap say not suitable for E85 but this website does http://www.dp-engineering.nl/bosch-040-motorsport-in-tank-fuel-pump.html

On that note, anyone know what makes an E85 pump an E85 pump? I'm not sure I buy the gimmick when I've been running E85 for longer than the designed for E85 fuel pumps have been around - where is the test of time?

Come around after work and fit my new 040 - will supply tools and pay cash more than RP pay you by the hour!

That^

I don't understand his logic...if he took it apart and found impeller blades corroded away it would make sense...but he's showing the mesh covered in sediment? These pumps sit at the bottom of fuel tanks and suck lol

He'll get a shock when he pulls out the walbro in 12 months and it looks the same...

    • I know it's an entirely different engine, but I noticed practically 0 difference removing or adding 2x 3in (5inch body) 400cell cats (one in each bank) with regards to sound. So changing the cat to change drone I suspect will have very very, very, very, very, very very minimal impact.
    • 200 cell cat will probably help. Do you have room to tee off a Helmholtz resonator anywhere along the exhaust? These can do wonders for drones, with a little experimentation with regards to length.
    • The car revs up through the gears much better/faster now, and fuel consumption doesn't really seem to have be affected either on a Hwy cruise, which wasn't expected  The FAB9 intake manifold has been problematic sourcing though, I've contacted Plasmaman to ask about their intake, which you can get different runner lengths spec'd, and, their different options for throttle bodies  The only real physical drawback with the Plasmaman intake is how to connect it to my current OEM style airbox, as FAB9 make a OEM style back half of the airbox to suit the larger diameter throttle body, and all that is required is a 30°bend silicone pipe to mate the throttle body to the airbox Car also goes in for some exhaust work in a week or so to fit the biggest resonator they can fit clearance wise in the front pipe to help remove some of the drone, there isn't alot of realestate under there, a rough guesstimation is it will only be about 3-400mm long and maybe 90-100mm diameter, and with a 60mm exhaust that doesn't leave alot of space for the internal volume of the resonator to do its thing I'm thinking I may need to bin the "high flow" 100 cell cat for something a bit more substantial, yeah, and restrictive, like a 200-400 cell, to help, but, I have ample room for a really large bodied cat to replace the current one which has around a 4" diameter body I may look around in the recycling bins and see if I can find a massive newish cat that was "replaced" with some new full exhaust system that the local exhaust shop in Western Sydney is doing
    • Hahah look at that smile 😂 Just like those ones on IG where they compare the husband in family photos vs husband going fishing lol. I don't think I'll participate this time, clutch isn't in and also the last time I went there were too many numpties on the cruise sessions. Nearly caused a few accidents holding up people and a few guys initiating massive kerb to kerb drifts with heaps of cars right behind them. Not to mention, there were guys on the track session using it as a power cruise session.
