044 In Tank

[T04GTR]

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

has this happend to anyone?

in a r32gtr

loose connection? enough fuel in the tank? did you put a fresh fuel filter in?

[T04GTR]

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

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?

[lebostyles]

i think the 044 is the external pump and the 040 is the intank pump. might help

[siksII]

yes the 040 is intank and the 044 is meant to be external but its fine to put the 044 in tank as long as u fit the standard sock as a filter

my mechanic told me bosch pumps are no good for skylines . ... .

[AlexCim]

and why not? was it just a "na, they are shit for skylines" with no justification?

[T04GTR]

hmm. that still doesnt explain why its cavitating

[Craved]

dave, is there any way the sock could be getting sucked into the pump and blocking it? i mounted mine external with a tank, so haven't looked at the sock/pump connection.

[siksII]

the sock cant be sucked back in because inside the sock there is a spring hanging off the input pipe so it does not collapse

no sock. just has the flat bottom with the mesh

[Craved]

its getting enough current to the pump?

could use your std pump as a primer/supply to the 044 if worst comes to worst

standard one is rooted,hence the replacment

[Craved]

ahhhh k fair enough..

[siksII]

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)

now its not airating the fuel and im much hapier

[Craved]

could it be a faulty pump then? still under warranty? good stuff its fixed now

[markimak]

that sounds a bit nieve. how can a fuel pump be shit..? they do the same pump fuel.. sounds like someone prefers a walboro. had one in my GTiR.. crazy little sucker.. forgot what psi it pumped out

what is recommended for GTR? ive only had it for 2 weeks lol.. time to start modding

[Tommyk]

a replacement pump from nismo/tomei/hks whatever, will pump at about the same as a bosch 044 (600hp?), it will be bolt in, and they only cost around the 420 mark plus shipping
