Gtr Fuel Pump

[blaikier33]

hello ive got an r33 gtst and i just pulled my pump out to replace with an intank bosch 023.

pulled it out and was a completly different setup to what ide thought, the pump is located up at the top of the tank with a long feed pickup that runs to the bottom.

i pulled the black rubber boot that the pump was in to get the part no. a42-621 b70.

is this a gtr pump, if so what one 32 33 34.. and how good are they

[paulr33]

GTR is fine and should be prefect for around 250rwkw

but they are as old as the car they come from, so keep that in mind vs a brand new bosch

[RBceffy25]

go tha bosch. headroom pays! as long as you dont mind some noise...

Not to mentionm its peace of mind as its brand new.

[blaikier33]

yes they are getting old now its mounted rite up the top of the tank could i put an o44 in there in the same spot and run a long pickup like what is already there. it would nearly be a strait swapover in the gtr cradle..

abit off topic but can you mount an 040 intank for an r32 gtr ? or are they external only ?

[blaikier33]

040 are internal only

What sort of HP will the 040 support? Tossing up between the 040 or ease of installation or the 044 for further headroom

yeh im in the same boat, need one to support 300rw-kw so tossing between these 2, but i definetly want to go replacement intank...

I use an 040 and its awsome. As far as I know it is well capable of over 300kw.

As far as external goes forget about a bosch.

You want to use a Pierburg push/pull external pump. These are an in-line style pump so no need for surge tank/swirl pot, no lines in boot, no fuel smell in cabin etc, etc.
