I found my Zetec saloon exhaust a bit too noisy with just one large silencer at 
the rear of the system (though it is a stainless Magnex system), and acquired a 
4-2-1 downpipe with a small silencer on it where the cat would be which will 
hopefully help.

Was the old engine (a 1.4 CVH wasnt't it) fuel injected ?
If not then there won't be a lift pump in the tank.
If you try running the high pressure pump directly from the fuel tank you will 
suffer fuel starvation on corners and roundabouts when the fuel level gets 
below half a tank or so.

You either need to change the tank for an injection one with an internal swirl 
pot or fit an external swirl pot with a low pressure feed pump and a high 
pressure fuel pump.
If you feed the fuel return from the engine back into the swirl pot then it 
won't matter that the high pressure pump is a lot higher flow than the low 
pressure pump.
There is a school of thought though that it's better to feed the engine return 
into the fuel tank to keep the fuel cooler as you aren't recycling the excess 
fuel between the engine and swirl pot.

  Hi Chris, the exhaust hasn't been done yet... the 4 - 2 - 1 that I have 
doesn't fit the engine. I have the stock manifold on there at the moment. I 
bought the downpipe with lambda but minus cat from a scrappy the other day. 
today I got the bits to make the rest of the exhaust. How much do you want for 
the pipe you have? The exhaust that is about to go on is going to be cobbled 
together from an escort downpipe, puma middle section and the back boxes from a 
puma sport... the polite word is hybrid!! 


  I managed to get the coil pack, exhaust bits and road speed sensor for £40 so 
quite pleased with that. We now have a spark but currently have no fuel getting 
through. I suspect that the lift pump has been disconnected from power 
somewhere during the mod. Just trying to find where in the loom I need to 
reconnect the power for this. I have concerns about whether this is going to be 
man enough to supply the hp pump  (from a 3.0 senator!) or whether to try to 
remove the lift pump altogether. It is top mounted and I don't really want to 
drop the fuel tank if I can avoid it.
