View Full Version : GTE/GSI Swirl Pot

Just thought I'd show anybody interested the swirl pot inside a GTE/GSi fuel tank. Principally the fuel returns at high pressure through the rubber hose, passes through the filtered area drawing in fuel from the tank in a venturi effect and swirls round into the main compartment. The pick up pipe sits down into the middle of the swirl pot.

thank you! i have not seen a GTE one before. i have only seen inside of the corsa SPI tank. i am intregued by the ballvalve on the filler neck. i did not realise there was such a device. i guess this prevents over filling and also petrol pouring on the road when the nova falls over on its side? also it will prevent bad man from next door from syphoning out my petrols!!!

Thats ace! I always knew it was there but spoke about through gritted teeth hoping I was right.

[edit] MC, did you find much crud & sediment in the tank?

My one I drained recently was really clean inside. Barely any crap at all.

There was a little debris, but the tank had been left open and I think most of it was grinding dust from cutting it open. Overall it was pretty clean.

At last, ive been waiting for someone to get a pic like that, nice one.

As everyone can see, it does infact contain a swirl pot and not some form of baffle. The pot is kept filled with fuel by the fuel return which the feed is then taken from.
When i removed my original tank, the pot did have quite a bit of crap sitting in the bottom of it.

For anyone wondering, the SPi ones are IDENTICAL to that too.

So what is the difference? :confused:

The spi pump sits inside the pot.
Whereas sri/gsi/gte one has a feed line going into the pot, with the pump on the chassis leg.

The spi tank setup is better IMO, the pump stays cleaner/doesn't get rusted to fook, and you dont have wires/pipes trailing about on the chassis leg.

So does the MPi Set up have an extra fuel line? I've noticed the MPi's seem to have 3 lines runing to the engine Bay. Are the SPis the same or just 2 lines?

Adam

They both have two. A 3rd line will probably be the breather to the carbon can.
MC-I bought a new tank a few month back, you can get them cheaper online! :p

I took my tank off the other day as it was leaking, i removed the senser/feed from the front of the tank by removing 6bolts. I then looked inside the tank and could see a metal swirl pot? There is a return at the back of the tank and im running an external pump.

My nova is a 3dr 1.4 SR running a c20let but im not sure which fuel tank to get. Been to local dingbro and seen the tanks they have, only one they have that looks the same with bolt on sender doesnt have a swirl pot in the tank. They said I must have an original GTE one?

I need to get a tank quite quick but want the right one, need a swirl pot as i use the car on the track, any suggestions?

Get an SPi Tank and fit a MPi Astra GSi fuel pump, its a nice neat and tidy job, no external pump dangling around. All you'll need will be tank mounted then.

I have found a tank which seems the same as mine, has a metal swirl pot in the tank and 6bolts to hold the feed/sender on so think I will go for that. My external pump has been used once and I like being able to access the pump easily, tank off job for an mpi one as my nova doesnt have the access bit where the back seats normally are

Dod

No need for a Tank off, theres an access hole under the back seat which allows you to remove the pump with ease!!

Mine doesnt have the access hole, unless i get the tin snips out.

In the rear under the seat? 6" Hole saw onto a cordless drill.

you will have to drive carefully with the top off your tank lol

if your binning that little plastic ball contraption can i have it

The one i have doesnt fit inside the tube so it blocks the filler neck and i cant fill up normally only at 20p intervals its a bit of a pain.

can i buy a SPi tank then and use that on my xe instead of the gte tank i have

Dod

Use the SPi Tank, Fit an internal Astra GSi Pump, If required, cut a hole under the rear bench as an access panel, NOT the tank....

Thats a nice interesting pic you've posted, my kind of image lol tank porn :D

Dont wish to Hijack but has anyone got a carb tank picture? The pipe that comes out the tank that goes to the pump does it have a filter?

Just interested to see what its like inside and also might help me diagnose my cars misfire issue as I recenlty drained the tank, if there is no filter on the end of the fuel outlet pipe then maybe its picked up some crud.

nice one MC... +1 rep added for that.

I love people posting pics to help others out :thumb:

wonder if mine has that in it? i presume not, as I was getting major surge prior to my external swirl pot installation

MC
17-06-08, 11:27 PM
Yes, there is a filter on the end of the pick up in the carb tank, but its not very fine so good for stopping large particles only.

The pics shown are from a standard tank, my new pattern part had a metal swirl pot inside, not plastic.

a uprated walbro pump for a corsa will also fit on the astra gsi craddle and fit in the tank correctly :thumb:

ALL nova injection tanks have swirl ports.
Which is why you should never get fuel starvation really.
Unless the engine is using more fuel than the standard swirl pot can supply to the pump.

Bit of a Hijack here, apologies!:)

What tank and fuel pump do you think would be best for bike carbs on an xe? because I know they have no return so would this brand the internal swirl pot useless as well as an external one???

Adam
18-06-08, 04:37 PM
If you have no return your probably best of with a carb tank.
Because the fuel return feeds the swirl pot on the injection tanks, which the pump then pumps from.
So without a return the swirl pot wont be doing much.

This swirl pot explains why I have never had any surge problems, no need for fancy/expensive swirl pot setups :thumb:

Just plumb the return into the feed line before the carbs.

As said, the only real need for a external swirl pot setup is if your using more fuel than the std swirl pot can supply to the pump.

Spi tanks are exactly the same, but the pump pumps directly out of the swirl pot(it sits in it)

The bolt on tank looks the correct one to me. GTE/GSi style screw in sender unit at the front.

http://bap.dominohosting.biz/bap/bapdb01.nsf/Plookup2/62-20-384VAUXHALLNOVA1983-1993!EditDocument&Ret=TANKS

Correct me if I'm wrong anyone.

19-06-08, 02:52 PM
LOL. Me & Dod disagree then.

Dod
19-06-08, 02:57 PM
The GTE/GSi uses an external Pump, the one I've discribed uses an Internal Pump. Choice is yours mate.

Craig, we're both right. But I'm a bit more righter. LOL

Adam
19-06-08, 04:11 PM
Aye, the bolt on one looks like a gte/gsi.
As the other "clip on" one has a arrow pointing to where the fuel pump sits(SPI tank)

Those prices are expensive too.

I paid £49 for my brand new SPi tank, and that included delivery.
Just checked where i had mine from and they no longer sell them unfourtunately.

19-06-08, 04:14 PM
so if i get the SPi one "clip on" what sort of price am i looking at for the fuel pump bit

Adam
19-06-08, 04:23 PM
Tenner from a scrapy yard.

If you dont already have a tank remember you'll need a level sender, which are rare as fook for some tanks.

i want a new one as my tank is rusting and the little plasitc ball doesnt fit in properly so i cant fill it up and the fuel flys out the filler cap!!!

SPi pump according to the site.
You need mpi.

Which tank are you buying? Internal pump?
