The place where your buying the fuel tank from should be able to advise you on this. If the tank is bespoke, try and use your existing pump.

i'm afraid i have sold the original fuel pump with the tank but i have been given a bosch fuel pump! It has an operating pressure of 300 KPA and a flow rate of 130 L/Hr. Would this one work at all? does anyone know?

bump does anyone know about the pump? i really need peoples input i would be very grateful.

Get yourself one of these

http://www.fuelpumps...0-70psi-7-p.asp

Then two cotton reel exhaust hangars to mount it , mine is mounted on what used to be the rear seat metal support , however my gf has hers mounted under the rear subby so its a bit more user friendly

It runs my 1380 with webber 45 nicely , i did have a fuel pressure regulator but my engine builder said i didnt really need it for what i was doing , always best to check though

thank-you for the input. Where could i ask to check though? I mean because it's electric fuel injection does that mean it is self regulated at the injectors? so therefore no need for a fuel pressure regulator? regards blue

i have a radtec fuel tank for sale if you are interested??

take a look at some of these pumps

http://www.fuelpumps...-pumps-23-c.asp

your best asking " sprockett" or "Dan" for the pricise in's and out's and full spec for fuel injection pumps , my cooper was an SPI , but had the carb convertion carried out.

And with my MOD hat on , please use the classifieds for buying/selling in future , thanks

I don't know what the spec for the standard pump is, but I suspect the Facet 'cube' is not going to cut it for injection. They are designed for carb engines. Sprocket will know more.

The regulator is built into the fuel rail. You just need a filter at the tank end, I assume you are keeping the original.

Stroker, are you saying that the fuel pump is inside your car? That's very bad prectise and AFAIK is actually illegal and uninsurable. If the fuel line runs internally it must be one single length of solid material with no joints. You should fabricate a fire bulkhead box to cover it and seperate it from the cabin. If you've already done this, I apologise.

thank-you very much for your input i will wait for sprockets input on the situation. I have purchased a new filter and a pre fuel pump free flowing filter

No worries dan,its all legal,safe and above board

Has anyone heard from sprocket i sent him a pm on this matter of fuel pumping but no reply

[skye]

bump. Has anyone heard from sprocket i did send him a pm about my predicament! regards skye

There is a fuel pressure regulator that.. regulates the pressure..

so if your replacement pump matches the original (3.5bar pressure).

Note that you will need a fuel return line back to the tank to return excess fuel..

That square brick is a pump for a carb.

You can use any sort of external injection pump, the popular one is the same one used for the Metro turbo. Plenty available on ebay, but it depends on how much you want to pay as to whether you get a genuine pump or 'something' else.

Plumb it up - tank>pump>filter>fuel rail. Keep the return as is, returning to the top of the tank somewhere, but not the tank breather. Use a fuel filter for injection. There are topics on the type of filter that can be fitted with barb fittings, nice and easy. Peugeot springs to mind.

Also be aware that if there is no swirl pot built into the tank, you will suffer fuel starvation with a low level in the tank and moderate cornering.
