Replaced standard fuel tank with long range tank..Now car keeps cutting out

[bj42turbo]

I just installed a 85L tank out of a VS Statesman into my VN v6.....It seems to idle OK, but when i drive it, it cuts out every 10 seconds or so....
Any ideas?

hows the fuel pump?

It would have to be running out of fuel for some reason. How much fuel did you put back in the tank?

its a external pump yer?

could be something as simple as the fuel filter got blocked up by crap tht was in the tank before u put it in

Internal pump
Not hearing anything when key at acc, the old / tank pump was very noisy

IIRC, the VN long range (V8) tank has two pumps, in lieu of the single (internal tank) high pressure pump for the standard tank. The long range tank has a low pressure pump internal to the tank, with a high pressure pump (with an external pulsator) outside the tank.

If you have simply hooked up the standard connection when you replaced the tank, then chances are you are only running the low pressure pump - which sort of relates to the problems you are experiencing.

You may need to add a connection to the external high pressure pump, to ensure it is running, to sort things out.
