G'day Im looking at under car surge tanks for my wagon atm and i was wondering if anyone had tried these ones and if they fit or not? http://www.ebay.com.au/itm/undercar-...em 35c0b95956 (http://www.ebay.com.au/itm/undercar-ally-surge-tank-bosch-fuel-pump-bracket-race-/230866639190?pt=AU_Car_Parts_Accessories&hash=item35c0b95956) would get it made for 2 pumps and with speed flow fittings on it aswel cheers

I am interested in an undercar surge tank for a wagon too. Where do you plan on mounting yours? Are the box shapes as good as the round ones? I am worried that it might have unusual flow characteristics causing air pockets that may starve the engine of fuel. Just an idea which is not based on any experience though.

speak to red star fab on here about making you a under car surge

I know JD customs under car surge tanks fits. Don't know about the one you posted. Looks abit large. http://www.calaisturbo.com.au/showthread.php?t=46412 Some original photos have not been recovered yet.

The lift pump makes sure there is always enough volume in the surge tank so that you can draw as much as you need, in reality the surge tank is basically full at all times? Consider it as a secondary fuel tank that is very small, and designed to always have enough fuel in there to keep your main pumps 100% fed.

yeah both the jd custom and red star ones are the same price and fit in the same place. only thing is im worried about where the pump would have to be mounted as my drive way at home is pretty steep with a big bump at the top. and a boot mounted surge tank is out of the question as i dont want fuel inside the cabin

JD Custom one: From memory I think it wasn't lower than the tailshaft. Going by the pictures, it wasn't. Some original photos have not been recovered yet.

I had a jd 1. Hated it always had problems. Ended up just putting 1 in the boot.

^really? I had one too and never had a drama!

Yeah the welds always sprung leaks n it cracked on the front side where the pump screwed in.

There you go then

Brightline fab make a neat undercar surge tank. Mounts in the standard fuel filter position

Thats not too bad acctualy Yeti, looks like the pump is no lower than the lower control arm mount. might be a go after i finish uni for the year and acctualy have money again Some original photos have not been recovered yet.

I had a custom 2ltr one made the bolts to the bottom of the spare wheel well between the rear of the tank and the back of the car up in the little void there.

With that under car set up is there 3 fuel pumps all up? Two original pumps + after surge tank . That's how my wagon is ! Heaps of current draw with all the pumps . Any one tried a vp commodore intank pump as the surge tank supply I'm thinking it could work .

i have a standard vl intank pump suplying my 3L surge tank and i have no dramas.

The little one intank only I didnt think it would of been up for the job.

i just replaced it with a new one. is doing me fine. with 1 044 from the surge tank. on e85 pushing around 300rwkw
