    Is there any particular reason for the change (ie changing from the stock carby setup) or what? If the car is standard, the original pump is simplicity (two nuts need attention to remove/replace) and reliability itself. The pumps generally being long lasting, just keep an eye on the fuel lines themselves, as they can become brittle with age.

    For a new pump try the usual suspects of French Connection or Caravelle Imports, both located in Melvegas.

    G'day Simon,

    I replaced the one on the old r20 with an electric as the pressure regulation in the original system was not worth having, immediate improvement in power and economy

    Poor old carby was being drowned.....

    Easy replacement Alan, goes down at the tank end, as they are better pushers than suckers. Mount it on rubber grommets to kill the vibration. If you are safety minded install a stall-cutout to knock of the power the next time you have a bingle. Fedtro 40104 is a suitable unit for our carby froggies, don't be tempted to get a bigger/stronger unit.

    cheers,
    Bob

    I gave up on a similar idea because of the cutoff switch needed. Tachometric relays are expensive and oil pressure driven switches need to be "normally closed" which makes them difficult to find. They are around, but it's a lot of messing around plus, if you go harder in a corner and have a bit of oil pressure drop in the system, your fuel cuts out.

    Really not worth it. You car Bob, probably had other problems the electric fuel pump overcame somehow. I am with Simon on this one, the original is cheap, simple and reliable and thank God still available. Now you try and find a fuel pump for a 205GTI.

    the problem was poor regulation in the original system because of silly design. The original is supposed to regulate by "bleeding" fuel back to the tank via a tiny steel line that is just made for buggering up. Obviously they didn't want to pay to use a sensible mechanical system that uses the line pressure to lift the lever off the cam.

    The Regie way managed up to 10psi No wonder the carby was drowning.

    I didn't fit any fancy cut-out switches either, and didn't have any problems with it, or bingles either, over several years totally trouble free. Of course that's a totally irresponsible attitude cos every time you have a stall situation, for whatever reason, a fuel hose is going to be off or you are going to be upside down aren't you with fuel spraying everywhere.....

    cheers,
    Bob

    If you have an R17 TS or Gordini head and/or cam shaft you have no choice but to fit an electric pump there was no provision on the engine for a mechanical one. The issue of safety cut out was discussed at length on another thread that asked a similar question.
