hi, just sorting the fuelling for the car i.e fuel tank pumps etc etc,

are 2 044 pumps enough one as lift pump to swirl pot other feed or use 2 for feed???

cheers

 

how much power are you planning on running, just to help with flow/pressure requirements.
one 044 pump will deliver around 500bhp IIRC.
feed pump to swirl pot will be fin ewith one 044 pump i'd have thought if avoiding massive power, alternatively use a low pressure high flow pump like a facet red top interrupter and that'll flow 37 gallons per hour.
all depends on how your engine is spec'ed etc.

 

How much power do you need to fuel for? 1x 044 pump is massive overkill to use as a lift pump to a swirl pot! Bear in mind an 044 is gravity fed normally and can fuel for over 500bhp being gravity fed.

 

its est 500+ 2.4 eight injectors etc etc

 

one 044 on a normal saff tank can flow for over 600bhp! so more than enough for most people!

 

37gph is only 168 lph

Bosch 044 even around 60psi will be flowing almost double that.

A lot will depend how you are plumbing the system as to how much fuel each pump needs to deliver and for how long.

Draw it out, then decide what is required.

But a single 044 wired and plumbed correctly as the main pump will supply 600bhp.

 

if one 044 is good enough what is best for a lift pump to feed the swirl pot?? a standard sapphire pump?

 

As already stated, that depends how you are plumbing the system.

Draw it out, and write down how much each pump must flow in order to maintain a fuel supply at each point.

 

Im looking at holley fuel pumps for a lift pump in my system,

Red 97gph/367lph

Blue 110gph/416lph

Black 140gph/530lph

 

I run a facet redtop as a lift pump to a swirl pot,

 

the red top facet i have may only flow 37gallon per hour, or 168 LPH, however my injectors only flow 151.1LPH (4xsiemens deka IV 630cc), so perfect for my needs at standard pressure.
at higher static pressure of 6BAR (900cc equivalent) i will need 216LPH, so would be inadequate for that.
at standard pressure it would be close to 500bhp though, so as a lift pump is absolutely fine as injectors don't run at max flow for long.

 

I've got a holley lift pump feeding a single 044 and swirl pot in the boot, can't remember what model the holley is atm, I'll have a look.
