Bosch 910 for GTR problem...

[JUN R33]

I just recently purchased a Bosch 910 fuel pump for my GTR but, am having a little trouble on having it replace my stock GTR unit.

I have been told that I need a pump in tank system and not just the pump itself?

I understand that the pump is 'inside' the tank but, cant it be installed externally?

Anyone who has a R33 GTR who can shed some light on this would be a 'GOD' in my eyes!

Thanks.

fitting the pump in tank is a little fiddly,but if u have a basic knowledge of hand tools ,its not that hard,u will need some fittings.

remove your pump from the tank and fit new pump in its place,then take the lot to enzed or pirtek and buy the fittings u need,they will be able to tell u what u need.

if ur not good at working with ur hands,dont attempt it.

I have just had the 910 fitted externally. My stock pump feed a 3litre surge tank, then the 910 feeds the fuel rail:D

I had fun (not ) fitting my 044 to my GTS-t. If the GTR mounting bracket and tank is similar, you'll need to bend the bracket back and to the side a bit, because the Bosch pumps are too big to squeeze into the small front corner of the fuel tank.

Pirtek won't have the fittings, I tried there when looking to fit mine up. They referred me to Earl's performance in Silverwater, who were able to help. I had to remove the small valve on top of the pump though because he didn't have the right sized banjo connector for it. It's only there to stop the fuel dribbling back down into the tank when the engine is off, but the regulator on the fuel rail does this well enough on its own.

Your best bet is to pull your old fuel pump out, and take the whole thing including the bracket and your 910 to a performance shop, and tell them you want to replace the old pump with the new. They should be able to tell you the exact things you'll need, and hopefully they'll have everything there for you.

The fittings and extra hoses and clamps you need should cost you around $60 or so. You can do it for less if you skimp on things like not fitting the factory fuel pickup, but if you don't you'll get major surge problems because the fuel intake will be about halfway up the tank. Also I've heard of pumps dying an early death if they don't have that extra filter sock on the end.
