Running rich ca18et conversion. help Please

[ollymk4escort]

Ive just just finished fitting my ca18et into my mk1 escort. took it for mot today and it passed aok. trouble is i put 15 quid in it and did 25 miles in it and almost used it all. It is running real rich you can smell it real strong when following behind.

So what could this be??

have i connected the fuel pipes up correctly??
My inlet pipe is connected to the rail and the return is after the regulator. I thought maybe the inlet pipe may go before the regulator.

Also there is no knock sensor connected as they have taken this away.

no exhaust sensor(o2 sensor??)

Any ideas to try and sort this problem as i cant use the car costing that much to run lol.

thanks in advance.
