What Intank Pump Will Deliver The Most Flow? Nismo?

[N1GTR]

Sell the 044's, throw something like an A1000 intank.

Boom, done.

[Marko R1]

So you bought it back well done. Was and still is I'm sure a great car!

yes the car is incredible & actually better than when i owned it lol

[Marko R1]

I assume you all mean 040 intank, because 044 is the external model

that is a misconception u can run an 044 submerged no probs!

what is an A1000?

Yea but why would you run intank, increases the chance of something going wrong, as well as reduced capacity, and more effort

exactly what I'm doing now

Aeromotive stealth

Just got mine $240 from ebay, did free shipping cos I bought it without bidding on Ebay

340lph @ 40psi and 13.5V

I was gonna take some pics of the install but it looks similar in dimentions to a walbro. Chances are I wont be able to do it this weekend either

Wut?

I've been running my 044 like that for years now, so has my mate and that single, in-tank 044 is supporting well over 500awhp.

IMO, the 044 in-tank with a stock-type sock filter setup is way better than the 040 with integral pickup, and the 044 flows more.

that looks like a good pump @ 340lph

have u fitted it as yet & are the dimensions similar to that of the oem gtr pump?

there are 3 versions of the 'stealth' so which is the right pump? would it be the 'centre inlet', 'offset inlet' or 'offset inlet/inline'

a few other q's:

1. stevo - the A1000 has serious flow (800lph @ 40psi), do u know if it fits in the tank of an r32?

2. pierburg pumps have also been recommended, do they flow as much as the aeromotive pumps as i cannot locate a website representing pierburg pumps?

3. the 'stealth' is rated @ 340lph on 40psi, what fuel pressure would the gtr run at high rpm/load? reason i ask, flow drops significantly @ 250lph on 75psi (as per attached flow chart) whereas the bosch 044 flows 200lph @ 5bar = 72.5psi

[bubba]

Marko, fuel pressure isn't rpm dependant, it boost dependant. Our systems are 3bar systems, if you're then running 2bar of boost then the fuel pressure will be 5bar at full boost

ok.

so my calculations should be based on something closer to 5bar fuel pressure as im running 21psi

[Marko R1]

My calculations are based on 5bar moving forward & here are my options...

1. Bosch 044: 200lph @ 5bar (more info: http://www.bosch.com.au/content/language1/downloads/fuelpumps.pdf)

2. Pierburg E3L series (700228510): 330lph @ 5bar (more info http://www.compsystems.com.au/index.php?option=com_content&view=article&id=106:pierburgefp&catid=2:ecu&Itemid=14)

3. Aeromotive A1000: 700lph @ 5bar (more info: http://aeromotiveinc.com/products-page/fuel-pumps/11101-a1000-fuel-pump/)

4. Aeromotive Stealth: 250lph @ 5bar (more info: http://aeromotiveinc.com/products-page/fuel-pumps/11140-340-stealth-fuel-pump-center-inlet/)

My concern with the aeromotive A1000 is if i can make it fit in the oem fuel pump cradle as it looks massivein comparison to the other pumps, there no dimensions available...

Pierburg flows 66% more than my 044 which is awesome...will the pierburg support 450awkw?

what are peoples thoughts?

thanks in advance

The Pierburg is very long and thin, like two Walbro's end to end.

The A1000 is around 3.5 inches round and 6 inches long as I remember. It can be mounted intank apparently but it is single speed, there are similar pumps around with variable speed to stop the fuel heating so much. These require -8 fittings and hoses at least for their rated output apparently.

Best and cheapest option is twin Walbro's cost and price wise, may not be the most reliable though but thats what I went for.

[Marko R1]

how did u set up your twin walbro's? any pics?

Designed as an external pump. Not saying it won't be fine, just saying it isn't what it was designed for

So? An 044 internal is fine, I use one and control it with Vipec. Stop posting crap.

The 044 doesn't have an open end like the 023 and 040....so you clamp a sock on the bottom of the pump and solve the problem.

The M35 pump is similar to the 350z, it sits under the rear seat. One Walbro and -6 line for each rail running ID1000's, non return valves before the reg should let me know if one pump fails so as not to run lean.
