i recently instaled a bosch 044 in-tank fuel pupm and after about 5mins of driving it starts cavitating and not pupmping.

its starts making a bouncing groaning noise, when you squeeze the hose it pulsates

umm. no full tank evrything good. pump just isnt hapy,

do they have to be VERTICLE in the tank?.

im a mechanic and not retarded(some may argue)

cheeres :D:P

ps. worth noting i removed the inline damper in the tank. this helped but still shit.

also the return that directs it back to the base of the pump.

(so it doesnt suck warm airated fuel.)

my 910 makes a groaning noise when there is about 12L left in the tank, and the car startsd surging when there is 5L left. when is starts making the noise it doesnt affect the pumping though.

i think the noise is from vibration and touching the fuel tank. does yours touch the bottom of the fuel tank?

if it has a mesh bottom it is not an 044, it is an 040!!

check the pdf as well. look on the box, it cant be an 044...

ok. its a 040 intank!! :lol:

doesnt matter i fixed it. i put a peirburg scroll pump from a merc in.

(had them from my old car)

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
