hey any help would or advise would be appreciated

I have recently installed an external bosch 044 fuel pump to a surge tank in the boot of my 92 R32 GTR and i have realized a sort of slurping noise through the pump and hoses after i have been driving around for a while.

I had to install the surge tank as i had replaced my intank pump with a Bosch 040, but had fuel starvation issues at a half tank of fuel when going around any right hander. Was told its because of the placement of the pump in the GTR fuel tank makes it a b!tch to fit the pump and the pump doesnt have a sock filter which means it doesnt sit as low as a stock pump did before.

So far i havent had any problems whilst cornering since installing the surge tank but im worried that i may have issues when down below half a tank of fuel and hard driving could cause problems. Is there away to modify the the 040 in the intank so it sits lower or to have a sock filter adjusted onto it so that i wouldnt have issues or have it sucking air instead of fuel to the external pump every time i get to half a tank? or is this something not to worry about?

Anyways back to the external pumps noises, On starts in the morning all you can hear is the normal whining sound of the pump and no slurping but after driving around the slurping sounds start. I was told this could be air bubbles running through the pump or hoses as the fuel starts to rush into the pump, the fuel heating up can cause the pump to change tones or the fuel in the tank getting slushed around causing the intank pump to send air up to the surge ( i dont think its this one because i had the tank filled to the brim and the slurping sound was still there but i thought id through it in anways :banana: ).

I was told not to worry as the car has been running fine so far and no fuel starvation issues thus far. is this something i should be worried about or is it in fact a normal sound?

Here is a link of a video with the sound im talking about that i found:

how did you mount the 040 on the stock bracket? i'm not familiar with the GTR setup, but i know that some people with r33's made a bit of an error when mounting an 040 on the stock bracket. they made the pump sit in pretty much the same place as the original pump without taking into consideration the fact that the stock pump has the hose and sock come out of the bottom of it, therefor it will be lower in the tank and then they end up with fuel starvation issues once the tank gets lower. when i mounted an 040 in a mates 33 i mounted it in such a way that the bottom of the pump sat as low as the stock pump. he was then able to drive with the fuel level low enough to get the fuel light to come on.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      What Music Are You Listening To?

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Yeah I would like to try and get a ADM car to reduce issues with insurance. I've decided if I end up getting this car I will set it up to be a sleeper build, leave it looking stock/dad spec on the outside I wonder if you can just drop in the 400r/Red/Z ECU or better still use a flashing tool to copy the map off one. Backup the factory map and then flash the 400hp cars onto the 300hp cars ECU?

      Nah, yeah, nah. Speakers have a nominal impedance of 8 ohm that looks more like 6.4 ohm when measured. The receiver's amplifiers (all channels) are all rated to 6 ohm (I think, it's been a long time since I cared). The real problem is that many modern class D amps have aggressive protection circuitry that cuts off the fun if they think too much current is being drawn. And with my speakers having series crossovers, as opposed to more typical parallel crossovers, and big TL enclosures, they can certainly dip down to lower impedances at some frequencies and that easily triggers the protection. Pioneer receivers are somewhat famous for it, but even Denon, Onkyo, et al, all have many complaints against them across various models. It only does it when listening to music at high levels. You have to be putting your ears at risk to do it. But sometimes I want to do that. If I was serious about using it as a listening room I'd simply upgrade the amp for the front pair to a nice Rotel or something, and just use the receiver for signal handling and processing - although that would be a bit of a pain in the arse too. Have to switch on more shit, pre-amp volume vs main amp volume, etc etc.
