Hey guys done a quick search and couldn't find what i was after.

Basically I'm deciding whether to mount my bosch 044 fuel pump in-tank and external with a surge tank for my rb25de+t. The main plan was to mount it in tank but after doing a little more research i am heading towards the direction of mounting it externally.

Basically what are your ideas on this?

As for mounting the fuel pump externally what do i use to push the fuel to the surge tank? Can i use a standard fuel pump or do i have to get a special lift pump?

And how do most people mount the surge tanks? Weld on a bracket and bolt them in?

Thanks in advance for any help

had external set up in my r33 gtst..

i used a factory gtr pump as a lift pump to the surge tank, and an external bosch pump from the surge tank.

i screwed the surge tank and pump in a bracket to a piece of aluminium, then screwed that to the floor of the boot. i also screwed an L shape bracket to the alumiunium to mount the relay for the pump.

the relay just wires in to the pump signal, so when the original pump is on, it switched the relay and the bosch one runs aswell.. i had it running straight battery voltage and had an inline fuse just in case.

its good insurance against leaning out, knowing that it can support 300kw, means it wouldnt be breaking a sweat at normal levels... its a quality part, that is brand new and reliable.

plus it makes a kick ass noise when its external.

Use an 040 if you want to run intank.

For an 044 use a low pressure lifter pump like a Carter gold and a small surge tank 2.5lt, you can mount it underneath the car so you don't get that horrible whine from your boot as well.

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
