I just finished mounting and plumbing up my 044 pump and surge tank.

The tank is a 1 gallon fuel cell I bought from summit, had 3 fittings added, 2 welded shut and the top sealed. Total cost ~$140.00. It is mounted in the storage hatch to the rear seat belt mount. The fuel lines go through the rear seat well using bulk head connectors and exit with 90's to the underside of the car to route to their respective locations.

The fuel pump is mounted in the spare tire well along with battery charge terminals and a kill switch. I used 3/4" round tube that I welded to 3/4" square and used longer bolts through the tow hook weld nuts.

The fuel comes in and out through bulk heads and using black 90s to keep it discrete.

All of this is to support a GT3574 kit from A-spec. Heading to the dyno in a few weeks. Should be fun....

Thanks. Just wanted to post these pictures for people looking for ideas on where to mount that stuff.

sweet
i always wanted to do that .... maybe i will when i get myself a GT45r or something along that line .....


please report back when u have everything sort out
i want to know how loud is the 044 crusing on the highway, i always get different answers

that's a lot of fuel for a turbo that size... I wouldn't even bother unless you were planning to go bigger later

so this is replacing the stock intank pump?

No, the in-tank pump feeds the surge tank and the 044 pulls from the surge tank and provides high pressure to the rail.

I always prefer to have extra than not enough. Going the surge tank route required an external pump and the 044 fits the bill at a reasonable cost.

On the loudness of the pump. Well I figure it can't be any louder than the holly HP on my pro-street chevelle. But I'll let you know.

That looks safe, hopefully nobody rear ends you or you don' t drive it on the street. Unless you have "much" larger plans in the future a twin walbro or supra in tank pump set up will put out more than anything that GT3574 turbo will produce without having to plumb fuel lines in the cabin and having to listen to that external fuel pump whine when idling and at low speed.

Do yourself a favour and hunt down an inertia switch and wire it in with the fuel pumps. That way in any kind of impact the pump will at least turn off if a fuel line is severed.Certain 80s and 90s Fords had them, so finding them at the wreckers should be easy and cheap.

I've seen 3574s lay down as little as ~350 to the wheels and a guy with a 3rd gen put down 460. I would think the 044 is about right. In addition I have an LT12 and have always considered a 3 rotor. Again go a little bit over board for not that much extra money and then not have to tear out and redo something down the road when plans change.

The car is not a daily driver so I'm not worried about the noise.

Unfortunately the packaging on our cars has made it difficult to find places to mount stuff, so that was the only option in the back. I'd be more concerned about fuel vapor more than liquid fuel leaks. That is why the surge tank was modified from having a removable cap to being welded shut.

I'll look for an inertia switch. Hopefully they aren't sensitive enough to trip on a hard launch.

This looks about right

an A spec 3574 is a GT35 compressor wheel (like a journal bearing T61, 61 mm inducer 82mm exducer, 55ish trim) with a P trim turbine wheel. It's all that much bigger than a BNR stage 4 in terms of wheel size, but it is more efficient due to the housings, manifold, and larger exducer. BNR stage 4 is a 60-1 wheel (60mm inducer, 76mm exducer, 60 trim) with the same P trim wheel (65mm exducer 74mm major)

ok, I have no idea what a BNR stage 4 puts to the ground.....

I just looked on the a-spec section and see plenty of 380+ RWHP and again some around 450 RWHP at 18psi. I believe a walbro is good for ~400 bhp. At 380 RWHP that would be around 450 bhp. You would certainly need 2 walbro to be safe.

I was going to go dual intank walbro pumps but was told this was a waste of money since you can still get fuel slosh and not get good pickup. Hence the external setup.

If you prefer to run intank thats cool. It's certainly cheaper and a lot of people run that setup and seem to get away with it. I don't mind spending the extra money if I think it's a better way to go in the long run.

I did pick up a inertia switch though. My fiance thanks you for that suggestion.
