I am not sure this will be of any benefit to any one in the UK as the price is steep and shipping would add to that.

The vendor is in Fremont California. I have not looked at it in person, but plan to soon.
This is a combo swirlpot/pump that can be used in a horizontal orientation approx 4 inches in diameter. I figure there are about 5 inches available in a rear subframe.

Here is a link to the vendor site:

Description:
It fully encloses a Bosch 044 inside a 1 liter reservoir. This allows it to be mounted in any position while ensuring consistent high-flow and pressure.

Looks quite neat

It's actually surprising it isnt more common though, as it does make a lot of sense. Only complication with such setups that I can see is the wiring entry into the chamber, which is why such setups are less common.

Here is another one, although leaving the terminals externally. Can be used dual or single with a blanking plate as far as I know.

Cant see an 044 being ideal for a Mini though. At low pressures it's capable of flowing enough fuel for around 700hp. Not sure if the Malpassi could cope with that and still maintain low fuel pressures needed

That's an interesting setup but the high flow is also something I'd think about. Even if the rest of the system can cope with it, there's a good possibility that it will heat up the fuel more than it should.

I don't know if a PWM controller on the power supply could be a solution.

It looks like the end fitting just shoves inside the end of the 044.

So with some adaptation, it could be designed to work with a lesser pump than the 044.

Or the square box I linked ( which should be available as a single box ) could be used with any Bosch pump

It looks like the US Rally Team site sells both the round version and the square version.

So what range of specifications in a pump would one want for a 1275?
I tried to find specs for different Bosch as I know they make many. The only link I could find that worked is from the Aus site:
http://www.bosch.com.au/content/language1/...s/fuelpumps.pdf
This one is the same diamteer but shorter:
0 580 254 046
207lph (3 Bar)
M14 x 1.5 M12 x 1.5 (F)
length 169
diameter 60

For ease of use, the bog standard Metro turbo ( AKA Golf GTI, Cavalier SRi etc of similar vintage ) pump is more than adequate in terms of flow, and has a simple push on barbed fitting for the outlet hose.

All Bosch pumps Ive come across seem to be the same diameter body.

I was planning on making something simular, mainy becuase internal pumps are cheaper

Using an internal pump is ok, but as I said. The biggest issue is sorting a sealed wiring connector to the pump for a swirl tank which will always be full of fuel.

Even OEM connectors arent submerged in most cases these days, as they have access ports on the top of the tank.

So cost would need balanced

For a supply of internal pumps, you could nearly get them for free off a lot of Jap tuners who all upgrade the factory pumps.
The factory pumps would easily supply a Mini though, as most are capable of 300bhp

I went ahead and bought one of the 034 versions. They are a local company and were willing to spend time with me even though I was only shopping.
It is a tight fit, but there is room.

I just need to figure out whether to suspend a mounting plate from the top of the subframe or the bottom of the subframe.

It may need a support bolt from the spare tire wheel well as well.



Still need to sort out where the feed pump is going to go.

If you have an 044 in there, make sure you have an adequate fuel supply to it. In a low pressure scenario, that's going to be flowing well over 300lph.
Also make sure your chosen FPR can cope.

That's easily another 100lph over most Bosch pumps that would be used for such an application.

Terry,

Have you talked to them about what they would recommend for lowering the pump output flow? I'm pretty sure the pump could be controlled through PWM and your ECU could likely do that using a solid state relay.

I did mention it to them and they felt it should not be a problem, but they may have a limited perspective.

I plan to thoroughly bench test every thing before deploying it on the car.

How fast can the ecu control a PWM output ? and is there any back current protection required on either side ?

I'd like to be able to control my pumps via PWM and SSR, but my DTA only has a max output of 1khz. Most of the research Ive done suggest this really isnt fast enough, with up around 20khz being more like what is needed.

I think in the case of the 034 setup, just dont use an 044. Just depends what outlet fitting the tank actually uses. But I think there are lower output pumps that have the M12x1.5 output fitting

The 034 setup is machined for the 044 form factor longitudinally. I found other Bosch pumps that have a shorter from factor and those would work with the Integrated Engineering square version.

If there is a Bosch pump with lower output that has the same form factor as the 044 I would be willing to try it, but I never found a listing that could confirm the form factor of the different Bosch pumps. All I found was the listing from the Australian site.

The ECU Terry is using has PWM outputs that can go more than 20kHz. The maximum is about 90kHz with a resolution of about 0.4% duty cycle.

While looking for econoseal and JPT connectors I ran across this:
http://www.efihardware.com/products/183/su...all-under-floor

It is from Australia. they also have a number of intank pumps.

Be just as cheap to buy one locally.

Going rate seems to be around 100 yoyo's most places.

Local to me is a long way from most everyone else. This one mounts at the top and hangs down. Someone had one like this before and the vendor was willing to change the mount position. When I inquired, they were no longer making them. Other vendors were not interested in making modifications either. If you have the skills one could certainly modify one of the bottom mount versions...

Your info says you're in the USA ?

Really...that must be the easiest place in the world to get stuff made ?

There are fabrication shops everywhere ?

I did end up going the fabrication route, but with an internal pump.

Originally I found this for American cars:



http://www.tanksinc.com/index.cfm/page/pty...=prod/prd84.htm



But it required more depth than a LWB tank could accommodate. So Nick at 7 Enterprises adapted the idea to a LWB tank. No reason it should not work, another expensive experiment if it does not. It does get rid of the extra lift pump, extra hoses and I can use the stock MPi filter in the SU pump position.

It should arrive today*Clapping*
