Fuel Leak - 2.0 Zetec on Jenvys

Evening fellas,

I've just put the car back on the road for spring(GTS Panther) and it's leaking fuel everywhere on tickover.

It's running a 2.0 blacktop with Jenvey 45's and a swirl pot with twin pumps.

It starts, runs and revs exactly as it should, but there's a small leak from the connection to the front of the fuel rail, and there's a large leak from the last injector to cylinder #4.

I've rebuilt the fuel line, injectors and pipes and it's still leaking on tickover, but it stops under load.

Any ideas what this is? Faulty pressure regulator or pump?

Thanks in advance!

Did you change all the seals for new ones?

Yes, re-balanced the injectors with new seals all round.

What's changed/been worked on over winter?

It was fine last time you had it out?

I guess if it goes away when you up the load then I would say maybe the fuel regulator is providing too much fuel, can you test the pressure in the line?

This is the odd thing, it went under the covers in November, all working the way it should.

I started it this week for the first time and this is where the fuel leak started.

I think it must be the fuel regulator, potentially failed or needs adjustment as it looks like it's putting too much pressure into the line.

I'll have a look when it stops raining!

Fuel pressure gauge, the thing virtually no one fits but makes this type of fault finding simple. Also don't use adjustable fuel regulators, buy a decent quality fixed pressure one (Bosch etc) and fit & forget. All this adjustable ones are a waste of time and money.

Give it a tap with a small hammer,atleast if that stops it you know it's dodgy.

Is the injector leaking the nearest one to the regulator?

I'm still waiting for the snow to clear before I can check it.

But yes, the biggest leak is coming from the injector nearest to the regulator.

Does that indicate it's pushing too much pressure?

Thanks
RR
