electrical bits on a rover v8 in a mk3 petrol hilux

Hi all,on holiday at mo but v8 stuff still going through my head. Was very lucky with headers I bought and only minor mods needed and wrapping them up.I bought the landrover v8 defender fuel pump on fleabay a while ago and now thinking about fitting it. Now some people say fit the pump close to the tank. Does this make a big difference as was thinking of bolting to bulk head. Also to turn the pump live where do I splice the live wire into?I'm guessing the ignition on wire but do I splice into coil or elsewhere?also I have a distributer which came with engine that has points and I have one without Wich came from the efi lump. Can I use the pointless distributer?and lastly the coil!do I need to source a rover v8 coil or if I can use the pointless distributer then a matching suitable coil? Sorry im pretty good with electrics but just want to ensure I get everything optimal!Cheers in advance,spenShare  Share Reply

On classic range rovers the pump was down by the tank, I knew a few people that moved them to the front inner wing with no ill effects, it does need to be set low.

Make sure you get the distributor with the separate box that the coil mounts on, the ones that reside on the distributor were prone to failure due to heat issues.

Just get a matched coil, I know the early points cars used 9v coils with a resistor wire within the loom.

Any of the electronic distributors (bar the opus...better known as hopeless) are far better than a points type. You need a lucas DLB198 coil

Mega Thanks for the replies fellas! Will have to see what the pointless dizzy is. In hoping I can employ or iI'll be looking for one to use as dont want points. Any ideas in the positive switch for the fuel pump?

Assuming your on carb/s, you just need an ignition switched +12v to the pump to get it going. To do it properly/safely you should have a couple of relays so the pump doesn't run when the oil lights on but does while cranking/running.

Oh man this is getting technical with relays and stuff!lol anyone have a diagram for the wiring? Its a v8 defender pump with a single live wire. So no switch wire as such!


Oddified - 20/5/14 at 02:16 PM

I don't have a drawing but do a google, there should be a simple diagram on there somewhere. All your doing is switching that single wire to the pump on/off at the appropriate times. To get it going/test just connect the single wire from the pump to an ignition switched 12v supply.

I am using a Ford Edis 8 with a trigger wheel on the crank pulley for mine. 2 ford coil packs.

Will be using a megasquirt or maybe a jolt, depends on whether I stick with the injection or go with carbs.

The thing that confuses me is how does the oil switch produce the 12v which the pump requiers?

The oil switch is normally open, and closes when there is not enough pressure. This is typically used to earth the oil warning light. What is being referred to is a way of stopping the pump if the light is on to try and kill the engine. However it gets a bit complicated as you want the pump running whilst you are cranking, but before the engine is running and the pressure has come up. It's a safety feature rather than something mandatory to get the engine running.
