Bosch 044 external pump help & fuel setup

Ive been reading up on pumps to get for my BMW 1jz project the Bosch 044 seems to fit the bill. Ive bought one off ebay but turns out to be an external pump no real bother to me just need help with all the fixtures and fittings.

Here is what I have so far

The BMW tank has the same design as the supra with a hanger and plastic nut design.

I have renewed the fuel lines from the front of the car to the back with 10mm copper

I have an aeromotive fuel pressure reg

A brand new supra fuel filter

650 injectors

oem 1jz fuel rail with threaded ends for flow and return

bosch o44 spec

Bosch 0 580 254 044 Inline Fuel Pump

Bosch 044 fuel pumps mount inline (out side of your gas tank), most commonly rear center under your car or truck. Each Bosch 044 inline fuel pump provides 300LPH of flow and operate at 72.5 PSI. Bosch 044 fuel pumps are comparable to the Walbro 255LPH high pressure inline fuel pumps which can both support vehicles for up to 600-700 horse power. Can be used in sequence with an intank Walbro or Bosch 040 fuel pump.

Bosch 044 Fuel Pump Specs:

Bosch Part Number: 0 580 254 044

Minimum Current: 12 Volts

Operating Pressure: 72.5 PSI (5 Bar)

Minimum Flow @ Outlet: 80 GPH (300 LPH)

Fuel Pump Location: In-Line

High Temperature Reduction: 8 GPH (30 LPH)

Weight: 1030 Grams (2.27 Pounds)

Fuel Pump Connections:

Inlet: M18 x 1.5

Outlet: M12 x 1.5

Electrical: Positive M6 / Negative M5

found this fitting kit on ebay

Am I going the right way here or should I flog the pump on and buy an in tank one?

are the 10mm copper lines ive installed large enough??

do I need the oem fuel dampener still?

whats the best way to plumb this lot together? any help and pictures will be great

Here's my set up from my Skyline

An in tank 044 with the proper pick up sock will be FAR simpler, you just need the sock and the fitting to convert the 044 pump you have.

I got one the kits and sock filter as CW mentioned, then adapted the hanger to fit... its not pretty as it has an NRV on it (may change this for a in-line one), but it works well..

As already said, drop it in the tank with a sock on it

You can replace the Bosch valve with an aftermarket one if you wish from somewhere like here:

It allows you to connect directly to it with AN/JIC fittings.

To get onto your hardpipe you may want to try something like this from Speedflow but you'll need to be using imperial aluminium tube to suit the fittings:

I know you said you have already fitted 10mm copper pipe, I don't think this stuff can be made to work with that but it may be worth a call to Speedflow to check. To be honest the aluminium stuff isn't that expensive but it always seem to be out of stock at Speedflow. I bought mine here instead:

ahha!

ahha!

Good or bad?

?

the check/nrv valve to remove the bosch thing

the check/nrv valve to remove the bosch thing

Ah - I see

Have you actually run one of those valves Dan? Do they hold line pressure as well as the Bosch ones?

Have you actually run one of those valves Dan?

Yes - done about 600miles or so with it fitted.

Do they hold line pressure as well as the Bosch ones?

I don't know how well the Bosch ones hold pressure to be honest so have nothing to compare to. I could see how quick my rail ressure drops and report back...?

Or if someone else buys one for themselves I could do some testing on one with pressure decay vs time at whatever pressure people wanted to see.

If it starts pretty much instantly after sitting for a few days I think you can assume it's fine. They could make installation in tank easier in some cases than a banjo fitting, that's for sure.

whats the advantage of the new valve?

The stock Bosch valve that comes with the pump only takes a banjo fitting, short of making something bespoke. Most in tank set ups sit more happily with the pump outlet coming off the end of the pump vertically, not at 90 degrees as a banjo union would. The valve enables a straight run off the end of the pump without recourse to bespoke fittiings. Some people run with no none return valve and prime the system each time, biyt it's a PITA on a road car.

You can see how a "normal" banjo brings off the line at 90 degrees in these photos of my twin external 044 set up for my Skyline engine below.

Cheers Chris, I think ive got a 90 deg banjo that might make the plumbing a bit more relaxed will look inot that also

Managed to get hold of the fuel sock but now come across the problem of the pump being to tall for the tank can I lay this pump at 45 deg but make an angled fuel sock socket so the sock sits flat to the tank? or am I better off mounting this externally.

my problem is then how would I do this as it has two pump style hangers either side of the tank, I think so it draws the fuel evenly from both halfs of the tank as the centre part of the tank sits above the prop.

do I remove the old pump extend the fuel line to sit in the bottom of the tank with the fuel sock attached then fit the pump externally to the other side of this line?? hope that makes sense.

Heres a pic of the bmw hanger with the fuel pump attached.

I've just done mine and it sits in the tank just fine...
