Fuel pump options?

[Glenelg15]

In the process of doing a NA to turbo conversion (full engine swap) on my ba xr6 and I need to do the fuel pump while I'm at it. I have 3 options at this point, walbro 255, A factory xr6 turbo pump, or something like a deatschwerks dw200 which is similar to the walbro 255. 

 

I've never heard a walbro 255 in a falcon before but I have in other cars and they are annoyingly loud so for that it's my least preferred option. The dw200 is nice and quiet like the oem pump but I have heard reliability problems with them and I havn't heard of anyone fitting one to a xr6 so I don't know if they would even fit yet without doing more research. 

 

Any other options? I would just drop in a walbro and be done with it but I don't want to hear the fuel pump at all if I can help it. Power wise I don't plan to push this thing very far due to reliability concerns of the na m78 lsd, maybe 250 odd rwkw max however an upgrade in the near future is on the cards however id still keep it under 300kw. What do the stock pumps usually top out at?

The Walbro option has been done time and again reliably in Falcons and is tried and tested, plus gives you some headroom over the factory pump if you want to push the boost past stock sometime.

I put a Walbro 255 in my BA sedan before the car died. It was super loud on prime when you key on (which I kind of liked) but couldn't hear it at all when the car was running.

The pump only did a few months in the BA and I finally got around to putting it my FG a couple of nights ago. Same thing - sounds like a race car when it primes, then whisper quiet.

Hopefully that helps if you don't know anyone with a Walbro you can listen to first hand.

that's good to hear regarding the walbro. Currently with the car in its NA form with a stock exhaust and factory fuel pump you hear a faint hum when it primes and then when its running and the fuel tank is low you can just very faintly hear a slight low hum but when driving you can't hear it at all. Noise when priming doesn't bother when but I don't want to be sitting at a set of lights and be able to hear what sounds like a blender full of rocks under the back seat. 

 

Initially I had planned just to buy one of the premade units on ebay with a walbro gss341 fitted but then I heard a mates car the other day with one and you could hear buzzing away it standing 10m away from the car. That said it wasn't in a modern plastic fuel pump under a seat but a steel tank under the boot.

I have a Walbro 255 in my FG F6 and Andrew said, loud on prime with key on but quiet once started. I kind of like the loud on prime noise too, reminds me that my car isn’t stock.

What sort of exhaust systems are you guys running? That'd help mask a lot of noise depending on the system. I think you've got me convinced just to go with the walbro. Fortunately these things are cheap and easy to change so if it drives me up the wall I'll swap it out with something else

BA was a loud job, but my FG is just 4" dump and cat and standard behind that, so very quiet at idle.

Drop in kit is a good option. You can save some money by fitting the pump to your existing fuel module, but is a bit more mucking around with hoses and clamps.

But good point - if you can hear the pump just get a louder exhaust - win:win

the walbro ain't a loud pump haha

It’s loud for about 2.5 seconds while it primes and then after that quiet.

[Glenelg15]

Walbro 255 it is then. If its loud while it primes that tells you its working haha

The module can also be fitted in about 15 minutes, easy as.
