Gtr Pump Questions!

[MANWHORE]

I agree about cutting off the tabs. I do that too.

You can use hose clamps mate. I have 2 hose clamps on the pump in my car.

I'm pretty sure that the wire on the side of the pump isn't for dual stage. It is just a ground. The reason I know this, is 32,33 and 34 pumps all have that extra side ground.

I didn't install the side ground for my car, and I do get the 2 stage. On idle, it's soft. If I blip the throttle, it goes louder.

Cheers

Got the old pump out. Compared to the GTR pump the physical size it is almost identical!!!!!!!

I got told the GTR pump is a lot larger.

Is The R33gtst part no. A42-T22 ??

Well Ive been having issues.

The gtr pump is a bit of a fiddle to get into the GTST.

You have to be careful with how your rotate the body of the pump. The GTR pump has a piece at the top (not sure what it is) Maybe a relief valve or something.

This fouls on the tank if rotated incorrectly.

See fouling on pic..pump couldn't go all the way down

Also when you take the sock off the GTST pump you cant use the post and lock washer as you need to rotate it to the same orientation.

Chris did you find the same problem? When you push it on hard it seems to hold pretty tight. Hopefully this is ok.

OLD PUMP

I still haven't been able to test it as I need a new tank seal as mine is rooted.

So for me it wasn't a 2 hour job

NEW/2nd hand GTR PUMP

Mine was different again. the R34GTR pump is fatter, cased in Rubber and is Black in color. Im also having issues, As also I cannot get it all the way down. AS the pumps casing has also its own Hose clamp on it. which is in a position that it fouls the side of the tank also, and I cannot just turn the clamp around as the clamp has 2 teeth on the far side of the clamp which earths to the middle of the pump. Wondering if i should just remove the pumps casing clamp altogether, but this earth will no longer attach..

Mine didnt have that Weird thing on top of the pump near the Terminals like yours does ben.

hey silver

I have a r34 gtr pump right here, and yes, it does have the valve up the top near the terminals.

just piss that stupid ground off. I chucked it out, and it functions perfectly.

[MANWHORE]

hang on ben. I'm a bit confused. did you cut the bottom of your bracket off?

When I installed my gtr pump, you know that metal pipe up the top? I had to cut that up (so I used to next nipple to clamp the hose). The pump was significantly taller.

that way, I could still have the pump sitting on rubber, sitting on that bottom part of the bracket. That's why I was asking if you had cut the bottom off yours

[benl1981]

Yeah I cut the bottom of the bracket off.

When you rotate the body of the pump so that the sock will angle the correct way the bit at the top fouls on the tank. SO I rotated the pump so it doesnt foul but then I can't use the locating post for the sock.

Was wondering how you did yours.

I cut some of the pipe you are talking about also.. so that it sat on the next bead..

[MANWHORE]

I pushed mine down as far as it could, but didn't see if it actually went all the way down (it did seem more down then yours though.

I had my pump oriented differently I think. Is your + terminal right next to the bracket? that's how i had mine.

[MANWHORE]

actually, is it meant to go down until that metal (groin area) sits flush with the plastic? if so mine's not that low.

[benl1981]

Well I got it all the way down now. My +ve terminal is next to the bracket I think. When you swapped over the sock it would be the wrong orientation if you used the locating post..did you just push it on as tight as possible and not use the locating post and locking star washer?

Edited May 6, 2007 by benl1981

[MANWHORE]

I have mine attached still using the bottom part of the bracket. For me, cutting the top pipe was enough. I have the sock clipped on.

I did it when the tank was full, so couldn't see how far down it went, but it felt the same as when i had taken it out.

Are you sure it's not all the way down? is that how it was when you took it out? if it's fouling, give the bracket a bit of a bend.

[MANWHORE]

Yep, my sock is the wrong orientation. + terminal next to the bracket. I pushed it until it goes click.

I don't see any problem with it coming off anyways een without the clip. coz it was pretty tight. it 'clicked' in

[MANWHORE]

so what's wrong with your tank gasket? mine was fine. I just popped it back in. You mean the ring that goes aroudn the top of the tank

[benl1981]

Well I guess that makes sense then. Do you have problems with when you get really low on fuel i.e. it not picking up the last 5-10 litres?

Oh, you didn't use the post either is that what you mean?

I don't see it as a major problem but thought maybe I hadn't lined something up right.

Edited May 6, 2007 by benl1981

[MANWHORE]

Haha, ok, what i did, is you could say the sock faces the wrong way. i did use the clip. Basically, the sock still points down, just slightly backwards. When I stuck it down into the tank, it still sticks down to the lower part of the tank anyways. No problem with low fuel (having said that, I normally fill up at about a quarter tank - I don't go down to the empty light. but even the empty line is fine on my car).

If you want the sock the right way, and use the clip, you could just bend the bracket out slightly, or space the pump out a bit with some efi hose. From the looks of your thing, even a couple mm would help it clear. But I don't think it'll come off even without the clip.

I can't believe that you cut the bottom of your backet off. There's enough room after you just trim the top barb back a bit. lol. I like that part, because from a mechanical point of view, imo, it would stop the pump sliding down. If I was you, I'd add another hose clamp on (yes I know it's clamped to the hose above). Like I said, I like things perfect, and i am anal.

[SilverECR33]

nice, Now it slots in the holster properly. hopefully thats the last time i gotta open it up .

Cheers.

[benl1981]

Well if you leave the bottom piece for the pump to still sit on it it has to be spaced out from the main assembly that I was hose clamping it to. So I just chopped the bugger off.

1 hose clamp will do..as you say the hoses are holding it and the clamp. There is no real load on it. Maybe some vibration from the unit but 2 is overkill. 1 in the middle of the 2 ridges on the pump is good for me...

My tank seal was a bit split and when I tried to put it back in its become all mangled. The petrol has deteriorated it and made it all tacky etc. the car is almost 14 years old now!! And I'm going to be pushing it to make as much power or more than a new 6L v8 hahah

haha. a hose clamp is $1.99 man, I paid $3, lol, but i was at supercheap auto today, the size is 032.
