That looks about 6X the size of the OEM one Are you keeping the OEM and using a swirl pot, or just taking a direct feed from the tank

[The Batman]

not sure yet ideally i would love to swap the oem pump for this one but i dont have the time or the money really..... as you might aswell swap for the pro alloy long range fuel tank with built in swirl tank while you are there! maybe for christmas so the plan was to use this as the feed from the swirl tank to the injectors its the bosch 044 pump

All you need to do is drill a hole and drop another pipe down there*




*Ok, so maybe not quite that simple

[The Batman]

tell me more

I may be completely wrong here, but I presume you want to use the new pump as the OEM one isn't man enough for the power level you want, so you plan to: OEM Fuel Pump > Fills Swirl Pot > Bosch Pump > Fuel Rail and/or Return to Tank But the limiting factor is the capacity of the swirl pot, which is essentially simply acting as a buffer tank Trouble is on long straights (esp the motorway) there's a good chance you'll empty the swirl pot if the OEM pump can't keep up (which you've already shown it can't) in which case the new pump may suffer together with your fueling I could however have this completely wrong, as the OEM pump will no longer be supplying a high pressure line (does it in stock form ), instead it will be open end For the swirl pot I'd imagine you want a feed in from the OEM pump, a mid point take-off for return to tank and a bottom take off for the Bosch pump The best solution would be to simply put a line into the existing tank (keeping the OEM setup for level indication) and feeding that straight to the Bosch pump, then use the stock return to tank line But as I said, I could be completely wrong

Hey joe, Hope your well. Where did you buy that header tank if i may ask? Are the plastic ones really crap at higher power? That beast is a aftermarket Fule pump right? Do you need a uprated fule pump on the higher bhp vx's ? On CS and TMS there power packs 4 dont seem to change that, Hence me asking you, or is there another reason? After the 5th , when i see you at a meet would love a pax ride if poss :-) Jim

I may be completely wrong here, but I presume you want to use the new pump as the OEM one isn't man enough for the power level you want, so you plan to:


OEM Fuel Pump > Fills Swirl Pot > Bosch Pump > Fuel Rail and/or Return to Tank

But the limiting factor is the capacity of the swirl pot, which is essentially simply acting as a buffer tank

Trouble is on long straights (esp the motorway) there's a good chance you'll empty the swirl pot if the OEM pump can't keep up (which you've already shown it can't) in which case the new pump may suffer together with your fueling

I could however have this completely wrong, as the OEM pump will no longer be supplying a high pressure line (does it in stock form ), instead it will be open end

For the swirl pot I'd imagine you want a feed in from the OEM pump, a mid point take-off for return to tank and a bottom take off for the Bosch pump

The best solution would be to simply put a line into the existing tank (keeping the OEM setup for level indication) and feeding that straight to the Bosch pump, then use the stock return to tank line

But as I said, I could be completely wrong

No it doesn't work like that. The operation of a pump follows a curve*, like a single speed line on a compressor map, that means that the less pressure head it has to provide the more flow it will give. Exactly how much will depend on the type of pump and specific design, also on top of this depending on how the motor to the pump is controlled as the load is reduced it could also spin faster so providing even more volume flow.

Also it will go tank pump -> swirl pot -> high pressure pump -> rail/reg -> return to swirl pot. the Swirl pot will take its highest outlet to the tank return. So the pot should have 4 connections to it. atleast one low one and then atleast 2 high ones and the other, well that isnt mega fussy where that is

this is the diagram i have been following:



and this is the swirl pot i have, it is a direct match to the diagram
