What do you guys think about the Aeromotive Eliminator fuel pump pn.11104 as compared to the Aeromotive A1000 pump part no.11101.And is it streetable.

Twin Bosch units!&nbsp These Aeromotive pumps are loud!&nbsp Unless you're crazy enough to stuff them in your gas tank - pretty anodize fins and all!

hey ted where do I get these bosch pumps from and what are the part numbers.

RETed

Kinsler has them for about $200 each, last I heard.
http://www.kinsler.com/
I've seen them called the "Indy Bosch" fuel pump, as they are used on the Indy Lights cars.&nbsp These are 300lph fuel pumps, as ask for the Bosch fuel pumps with those specs.&nbsp There are several models available, depending on what kinda fittings you want on them - AN, metric, barbed hose, etc...

If you need a lot of fuel, then Aeromotive is the way to go and their A1000 pump runs like $299, you only need one and they last about 30k miles. If you have a single turbo FD w/o cats then you won't even hear the pump!!

RETed

The Aeromotive fuel pump equals 294lph.&nbsp Run the numbers and covert their gph to lph.&nbsp The Bosch is rated at 300lph - pretty much the same thing.&nbsp At $200, the Bosch fuel pump is a better bargain, and a little easier to install in the tank.

Well they claim 500 GALLONS per hour. So it flows alittle more than you think. I have seen these pumps support close to a 1000 flywheel horse power w/ a single pump. I run a 255lph intank pump and a 240lph inline pump and together they can't support more than 700 flywheel

A couple dumb questions here, and one whacky idea..

The Bosche's are in-tank pumps, correct? So, there is some extra hardware in the tank, and a second set of lines (output and return) running to the front of the car?

Would the twin Bosche's be plumbed in parallel? Ie. one feeding the primary rail, and the second feeding the secondary rail?

Last, just a thought (I haven't run the numbers yet), but if I was running two pumps in parallel, and had two sets of lines, wouldn't a stock TII pump be enough to handle a pair of 550cc primaries, and a Walbro (255lph) be enough to handle a pair of 1680cc secondaries (assuming a 1:1 FPR, and less than 20psig of boost)?
Or, maybe a pair of Walbro's?

Seems cheaper.
Am I out in Left Field here?

I don't know what you mean by an "A1000" model, but the only thing I see is this one...
http://www.aeromotiveinc.com/products/1000hp_pump.shtml

It does mention "500 lbs. per hour" which means you have to divide by 6 to get gph equivalent.&nbsp I am not aware that Aeromotive has anything that can flow anywhere close to the 500gph you've mentioned; I only know of Weldon who makes fuel pumps that can flow that much gasoline.

They were designed to be in-tank, but I've seen them mounted outside the fuel tank.&nbsp If you want to run twin lines up front, you can do that.

Parallel fuel pump will double the fuel flow.&nbsp If you want to run one per fuel rail, you may do so.


Sure, a stock FC turbo fuel pump can support up to 250bhp.&nbsp I pair of them will support up to 500bhp.&nbsp A pair of Walbro will support up to 700hp - this is what a bunch of the JZA80 (Supra MkIV) owners uses...

twin in tank looks pretty good. soul assassin has that setup

qwck10th

Only problem I can think of with the dual pump/parallel setup is how and where to measure fuel pressure...

If a single FPR with dual inlets and a single pressure nipple (like the Aeromotive or SX) is used, and one of the pumps dies, what fuel pressure gets reported ?! That could be a very expensive question to get a wrong answer to:o

Seems like a FPR with the dual inlets AND dual pressure nipples is the answer, unless the units with a single pressure nipple "report" the lowest pressure of the two inlets. Hmmm.


So the $64 question is: with dual inlets, and a single pressure nipple (on a dual pump system) what does the pressure gauge read if one of the pumps dies???

s

RETed

Interesting question...you really want the fuel pressure measured at the fuel injectors, so closer to the fuel rail would be better.&nbsp Ideal would be to run TWO FP gauges, but this gets a bit ridiculous.&nbsp I would run the FP sender at the Y-splitter myself.


Does it matter?&nbsp I think as long as the fuel pressure stays high, you're fine.&nbsp Of course, this doesn't necessarily mean that one fuel pump is dead.&nbsp Maybe we can run a microprocessor controlled circuit to check to see if both fuel pumps are working?

With the dual pumps, would you still get power through the stock wires in the tank OR would you run power straight to them from the battery with a relay?

Would the dual pumps cause idling problems?

It is smart to be sure that you have enough fuel, but it is easy to go overboard. Running parallel lines to the front of the car increases weight, complexity, and hassle -- do you really need this, or are you just having fun with SS hose and AN fittings? Going way overkill does not make you go faster, it is just way overkill.

one huge-*** in-tank pump & stock lines (including the rubber ones)

Many good thoughts...

Max: no S/S lines, or AN fittings for me - just trying to save some money using the pumps I already have - the trade-off is I'd have to run another set of stock-type lines to the front, and figure out how to mount another pump in the tank. Kind of a hassle, but maybe less $ than another pump.

I looked for the Apexi pump on the SR site, but couldn't find it. What was the price? I like the ND pump (RX7 store) it supports my HP goals (450bhp), and like the Apexi, both are low-hassle alternatives to the two-pump setup.

I think Max is right though, the hassles for the two-pump setup are:
O welding together a new in-tank mount for the second pump.
O A couple AN->barbed hose fittings to bring the new lines out of the tank.
O Finding and installing another set of stock lines, and another fuel filter.
O The dual fuel pressure gauge problem.
O The wiring hassle.

Trout: as far as rewiring goes, maybe Ted can address that (my Haltech is sitting in the basement). I know the ECU will need a relay so it can cut power to the pump if the motor isn't spinning (ie. in an accident). For the FC, a fuel pump rewire is good practice regardless.

LOL... a processor to monitor fuel pump operation

lots of good details in here, and interesting stuff to think about.

Thanks everyone.

Max, I reread the post, and found the pump...
Thx,

At this stage of power, I would assume that you're serious about your mods.&nbsp Rewiring is highly recommended.&nbsp I would also assume that you're running a Haltech or equivalent - idling is not a problem when fuel delivery is readjusted.

I can hardly hear my 1200 hp aermotive pump, and I have the stock cat back. Addition of a catback and I'll never hear it. Trick is to not mount the pump on the frame, it is a lot louder mounted driectly to the chassis.
