Thread: Power loss on hill climb

Could it be the fuel pump as they start to show signs of wear on hills first.

Yeh, it does sound like a fuel problem.
I see that a special tool is needed to remove the pump, is there a way around this? Is there a pressure test or something that can be done to prove the pump? I suppose new gaskets and what not are required after removing the fuel pump.

You can get lucky and sometimes reuse the gasket, but there is a good chance you will need a new one. And i am sure you have to buy a whole new pump to get the gasket. I used cardboard on my zook but i wouldn't recommend that .

As for the tool? i am unsure but i am sure someone on here would be able to help.

I had a look at some photos on Famous fours website and it looks the same design as the RRC plastic fuel tank pump.

If so the method of sealing in the tank is a BIG plastic cap, like the cap of a kitchen canister without a top if you can imagine.
You can undo it by holding a screwdriver against one of the raised bits and tapping with a hammer.
The gasket should be OK and they can be bought separately.

Unfortunately there doesn't seem to be any bodgee setups for the D2 V8 like using a Commodore pump, as the pump works at a higher pressure and the fuel pressure regulator is also fitted in tank.

I think from earlier posts that they are about (SITTING DOWN???) $800.

Thanks Philip,
I'll pull the pump out on the weekend if I have time. Hopefully it's just a filter blockage or something, however I can't figure out why the motor wouldn't run well in neutral on an steep incline (even after having left it parked for an hour), but it would run well (eventually) on a flatter surface.
Thanks again though.

AFAIK from earlier posts there is no fuel filter in a D2 V8 .

Electric fuel pumps usually all have a "sock" on the bottom of the pump, and if it develops a split the small entry of the pump can get blocked or partially blocked.
Ask me how I know.
There is a place in USA that would probably sell a high pressure pump to suit.
Iwas thinking of Walbro but via the Range Rovers .net site found this.

The fuel pumps are right at the bottom of the list. The pump looks like a normal pump and the regulator sits at the top of the pump assembly in the lid.

I just remembered why you cannot do a cheapo pump replacement on a D2.
Apparently the assembly is welded together unlike the older models which come apart by undoing some tangs.
BUT hey you can be a pioneer.

Do you remember how much fuel you had in your tank at the time?

Someone else can confirm this, as i dont know exactly where the fuel pump pick up is.

But, if it's towards the front of the tank, and you're low on fuel, when you point your nose up the hill all the remaining fuel sits at the back of the tank, and the pump will struggle to pick up fuel.

Again im not sure, but if the tanks incorporate a "swirl pot" (an internal surge tank) you'll get up the hill a bit, but once the pot holding fuel empties it'll suffer fuel surge.
Then once you're back on flat ground and the fuel levels, the pump can pick up a constant supply again.

If the fuel pump pick up is at the rear of the fuel tank, disregard this whole post And if you had a fair quantity of fuel in the tank this probably wouldn't be the issue either
