Cubes Posted December 20, 2003 Share Posted December 20, 2003 Is there any other fuel pumps we are able to use? I remember seeing an intank Nismo fuel pump that flowed 270litres I think it was. Bosch 040 pump is 235 litres per hour and supports 520 bhp at 73.5 PSI.

Guest INASNT Posted December 20, 2003 Share Posted December 20, 2003 040 is also a very good pump to use and is internal designed Link to comment https://www.sau.com.au/forums/topic/30069-mounting-a-bosch-044-fuel-pump-intank/page/2/#findComment-613658 Share on other sites More sharing options...
Cubes Posted December 21, 2003 Share Posted December 21, 2003 I've found one... Based on the following table: Bosch 910 pump is 200 litres per hour and supports 450 bhp at 73.5 PSI Bosch 975 pump is 228 litres per hour and supports 500 bhp at 73.5 PSI Bosch 984 pump is 228 litres per hour and supports 500 bhp at 73.5 PSI Bosch 044 pump is 330 litres per hour and supports 730 bhp at 73.5 PSI Bosch 040 pump is 235 litres per hour and supports 520 bhp at 73.5 PSI There is a Nismo 4.1Litre per minute or 246 litre per hour intank pump that should support approx 540hp. Greenline sell them for ~$500 AUD.

Cubes Posted December 21, 2003 Share Posted December 21, 2003 Yep but its a NISMO JNR24. So that makes all the difference, lol. I paid ~$200 for my Bosh 910.

JNR24 Posted December 22, 2003 Author Share Posted December 22, 2003 Just a thought.... Would it be possable to run twin pumps, intank? Like run a 044 & a 910???

whistla Posted December 22, 2003 Share Posted December 22, 2003 if your pump does the same noisy thing when hot then I guess they all do it i was going to mention this! was curious to know if anyone elses gets annoyingly louder when its hot (long drive + warmer weather) im not sure how mine was mounted (its intank), but the only issue i have is that when the fuel gauge is on the second last notch, its classified as "empty" and will surge if it goes lower and i dont fuel up Link to comment https://www.sau.com.au/forums/topic/30069-mounting-a-bosch-044-fuel-pump-intank/page/2/#findComment-616185 Share on other sites More sharing options...

Steve Posted December 22, 2003 Share Posted December 22, 2003 I have put 55L in mine, guage was well and truely on empty, and it didnt surge - that was with bosch 044. If you have surge, there is a very good chance that the pickup isnt correctly located. next time you have low fuel, try pulling the pump, and checking that the sock is in the right spot, ie, it locates in the little section at the bottom of the tank designed for it to fit. Also, check the tounges on the back of the fuel pump bracked are secured (fitted) properly in the locator.

JimX Posted December 23, 2003 Share Posted December 23, 2003 Err yeah, but why? Edit: in tank it will be farkin' expensive. You'd really need to put them in a custom surge tank. But again I ask why? The 044 handles up to 700hp on its own. Combined with a smaller pump you might find it harder to control the fuel pressure. If you want to pair them up it's best to use the same pumps.

JNR24 Posted December 23, 2003 Author Share Posted December 23, 2003 I was thinking more about security & piece of mind rather than needing more pressure & flow. If one fails you have another still operating....? Just thinking aloud.. thanks anyways Link to comment https://www.sau.com.au/forums/topic/30069-mounting-a-bosch-044-fuel-pump-intank/page/2/#findComment-616279 Share on other sites More sharing options...
JimX Posted December 23, 2003 Share Posted December 23, 2003 If one fails you'd never know, unless you had a really keen ear. You'd be better off just carrying a spare of the same type and the tools to fit it, if you were really worried about pump failure on the road.

Brody Posted December 23, 2003 Share Posted December 23, 2003 The "surging" noise happens because Skylines have a variable resistor for the pump. When 100% fuel pressure is not required ie at idle or light cruising, it increases the resistance and the fuel pump slows down. With the PowerFC it seems to vary this a lot more between simply "on" or "off" like the factory ECU does. It also seems to want to vary a lot even when just idling, so the noise becomes a bit more annoying and "groaning" kinda because it dips up and down rather than just clicking between high and low pressure like with the factory ECU. Joel, if your pump does the same noisy thing when hot then I guess they all do it. Design flaw maybe? Ive noticed this with my 32...Anything below around 2800rpm, u get the shit groaning noise on/off. Though reving higher I never get it. Is there anything that can be easily changed? I get pretty much the same noises on empty or full.

Cubes Posted December 23, 2003 Share Posted December 23, 2003 So you have the pump mounted externally? Originally my pump was mounted directly the chassis and petrol tank. I used to be able to feel the vibrations at my feet when driving through the floor pan. I have since rubber mounted it and the noise can still be heard all though it is now heaps quieter & the vibrations have totally gone. Before you get under the car take it to a car wash place and hit it with the high pressure hose up inbetween the diff and petrol tank other wise you will have lots of dirt and junk in your eyes by the end of the mod.
