you can have it in the boot so long as it is completely sealed and drains to the outside, can be costly, i got one made to a design I made, it has a 2.5ltr surge tank and two 044's, has three 30mm id alloy pipes the go through the boot that act as the drains and the hoses go through them

Similiar to N1's just with out the pretty stickers

http://cgi.ebay.com.au/Fuel-Surge-Tank-Und...=item3356ba225b

Doesnt appear to have the capacity above the pump Steve-O's does

curious coincidence the sellers name is Brad????

The current ones I'm using on my GTRs have individual chambers supplying the pumps and are foam filled to settle the fuel a bit more.

I rather use them with dash fittings as opposed to barb tails and clamps.

They work well and are realativly inexpensive.

Any more info available on these like the sound of the foam too, pm if ya prefer

Does it mount in roughly the same position??

Flow was a concern as Brad and Greg figured out the tank had to be over 4L for the pumps I'm using.

Safe too assume 2 x 44's or bigger?? Or was the lift pump more the issue??

Was planning on using my Nismo in tank as a lift then probly two 44's

Speak to EFI performance. Pierburg external fuel pump. No need for surge tank.

i am looking into this setup myself & will confirm tomorrow if this pump can run on its own - surely this is the way they run it in their high spec mercedes cars?

Surgetank above is from here http://www.processwest.com.au/website/prod...elantisurge.htm

Usually around $900-990 with pump. Often you can pick up one from the XR6 Turbo Forum Classifieds a lot cheaper....

i spoke to these guys this morning & they dont make surge tanks for the gtr

Yes I know what a surge tank is for. I understand what you are saying but I have been assured you wont need one with this setup.

Here is a 'quote' from an email from Rick at EFI

"We recommend you look into an extra external pump we use and recommend (pier berg) high volume fuel pumps which are a draw and push pump capable of 350L per minute @ 3bar where the bosch 044 external is only a push pump and with its expensive fittings ect they are rated at only 200L per min @ 5bar."

"We have used these pumps on over 40cars now and are really taking off, they can be used with C16, methanol and are also E85 user friendly where the bosch pumps are not."

Like i said, I reccommend speaking to the EFI guys. They are really helpful and great to deal with.

Any love for the PierBurg?

hey adam - i spoke to rick @ efi performance in qld. he said i could remove my surge tank & replace my lift pump with the pierburg pump on its own (either run it in-tank for a factory appearance OR under the car with a simple bracket) & this will support 500awkw no problem. also is alcohol & ethanol friendly

he explained that the 044 is rated for 200lph @ 5bar & the pireburg is rated for 360lph @ 3bar, most pumps loss efficiency with higher pressure however the pierburg remains flat & says easily maintains over 300lph @ bar.

they use these in mercedes sports cars & the bugatti veyron actually runs 4 of these pumps (1 for each bank) in the tank as they are submersible.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
