fuel feed pipes

Tony if you are taking the tank out, could you not get a pump and swirl pot ( complete unit ) from a BMW and get the tank cut open and fit it in the tank. This is what I have and no problems so far. The idea of a swirl pot is the return line returns the fuel to the tank in this causing the fuel to swirl in it this has the effect of actually holding the fuel in the pot when the level is dropping so when cornering it reduces the risk of the pump sucking air. The reason for this is these pumps burn out very quickly due to the high pressure they work at if they try to pump air. HTH

Tinka,

VW and Seat do have a swirl tank outside the main tank that holds the electrical pump too.
It reduce the noise of the electrical pump (submerged in fuel)
I think that it would be easy to install and cheap than any BMW stuff.
See pictures.

The swirl pot and pump I got cost £15 from a local breakers, it is a pain to fit as you need to cut the tank open as I mentioned but once fitted you cant hear the pump at all except for a 3 second burst when you first turn on the ignition and it primes and pressurises the system. But if Tony has the room your system would be easier to fit, just most of us are really tight for space.

NO just gravity and a short hose.
Be careful with the pressure, there are different models there.

Tinka,
YES the first option would be a submerged type (new tank) at the main tank and forget the swirl pot.
But work at a fuel tank after it was used can be very dangerous and only for specialist.

All
Remember no matter how much you clean, it will contain hydrocarbons.
Steam blowing (long duration) and always with a hydrocarbons sniffer than you can work on the tank.
Caustic Soda will help to scrub the big part but not all.


Please be careful!
