Ha! More than welcome to try it Birty!!

I've resorted to keeping the tank 1/2 full at least!  :lol: :thumbs:

Me too.
Also keeping wifey behind in a Nissan Qashqai pace car is good for other road users.
Off to Tatton Park at weekend so plenty of time for it to play up

i have had the same problem with my caddy tank for ages. turns out there is a metal pipe that is supposed to be connected to the outlet by a small rubber pipe but it had fallen off.

Interesting. Which side does the pipe run from and to? If that makes sense??!! Which end is open and which side is connected when the tank is in situ? 

Is a caddy tank the same as a cabby??

I've had the same issue. As RJ said there is a round rubber bung that is under the filter in the base of the swirl pot, it falls apart and the swirl pot no longer works. If you google 'golf mk1 swirl pot' there are a few pics.

Most of the crud in the tank collects around the swirl pot so are accessable through the top. I used a syphon tube, the small movement of fuel was enough to hoover all the bits out (tried the magnet trick but a lot of bits were not ferrous).

I changed the tank in the end to a pattern part and can say that I have had no issue with starvation even with the primative swirl pot that these use.

Hope this helps

Interesting replies.

yeah the tintop diesel tank swirl pot is a lot simpler iirc, its just a round cup spot welded to the base of the tank?

Where should the rubber hose be ? on the tapered end copper pipe ? and to where ?

My cabby tank no doubt doesnt have any of this inside but suffers from the fuel starvation turning right so i need to make something to suit, i thought the accumulator was supposed to supply a constant feed to the metering head, obviously not so some after market reservoir must be needed ???

this write up is pretty good at explaining whats knackered… http://www.clubgti.com/showthread.php?194372-Mk1-Golf-Fuel-starvation-on-right-hand-bends%E2%80%A6-Analysis-and-conclusion but not the cure, could it be as simple as adding an ebay swirl pot ? found all this (cut'n'paste) but will require someone more knowledgeable than me to apply the maths to a KR engine so we can buy swirl pots of the correct size and plumb them in after the intank pump but before the external pump :$
"There seems to be a lot of debate regarding how big you should make a fuel surge tank. Everybody will give you a diffrent answer from no surge tank at all to 3L. Some people even claim you need a 5L one for drifting So I'll try and clear it up for you (the way I see it, if you think I'm wrong please abuse me!) The size of your fuel surge tank really depends on your engines fuel system. You can use maths to work out how big it needs to be: Take for example my RB30/25. It runs 6 fuel injectors that flow 270cc (270ml) of fuel per minute at 43psi (2.96 bar) at 100% duty cycle Therefore your total maximum fuel flow is 1.620L per minute. This figure is calculated by multiplying your number of fuel injectors by the size of your injectors. So in a surge condition in your fuel tank when your lift pump is sucking nothing but air a 1.620L fuel tank will give me a whole minute of surge "protection" But really the sort of turn that would create a condition like that would have to be a big one. I mean how many places are there where you can pull a high G turn like that for over a minute (beside the donut pad!) I doubt that drifters can hold a high G drift without changeing direction for over a minute. So what I do is half that figure. So now I'm down to a 810cc (.81L) surge tank. Its small and compact and gives me a whole 30 seconds.
any thoughts ?  the UK retailers only seem to list 1ltr and above some of the US sites do the 0.8ltr ones, the best result would be to find a car that had one as standard so we can raid the scrap yards !!!

800ml should be easily big enough (given the delivery rate) and if you route the fuel return via the swirl pot even better.

if you want a standard one look at post-84 cabrio and scirocco injection plus all g40 shape polo. its a small plastic unit about the size of a fuel filter

where is it located ? did a search for VW swirl pot and got nothing  apart from a repro tank at £80 ?

Post

Back to the top
found a part number for a G60 one any good or should it be g40, does it make a difference ?

yes thats the part number for mk1 cab/rocco gti or g40 shape polo :)

not a g60 one though, they either have fuel pump inside tank or use mk2 type external fuel pump which sits inside a fuel reservoir.

edit: its under the car in front of the fuel pump, where the accumulator used to go on a tintop

edit2: it doesn't haver to be g40 polo either, ALL G40 shape polo have them regardless as they were all fuel injection (poverty spec were rubishy SPI setup but still counts as fuel injection :lol:)

We had a terrible fuel starvation problem on right turns in our stock 1984 GTI in the 24 hours of LeMons……We sidestepped the problem by replacing the old tank, always running with more than a 1/2 full on the fuel tank and also making sure the tanks was vented properly (ours was not).  Good luck…..Scott in CA

i didnt do any of this with the ebay swirl pot (ETKA fuel filter  O_o ) as i thought the air gets in to the pic up in the tank, thats where the swirl pot is supposed to be, the idea is to protect the fuel pumps (both in tank and external) so whats the point in having a swirl pot after the in tank pump  :P

Hoping a GTi tank will cure this.
