Farmer_Terry Posted April 18, 2015 Share Posted April 18, 2015 I have one of these fitted to my car. The engine is a 2 litre zetec with two twin choke webers and the fuel pump is electric.It started to leak at the end of last season, so I had to dismantle and mantle it again. The leak is now cured, but I don't have much idea how to set it. The page shown in the link recommends setting it to around 4 psi - is there any more information I should have?All tips, hints, pointers or general advice gratefully accepted, as always.

Guy Lowe Posted April 18, 2015 Share Posted April 18, 2015 I used the same Sytec regulator when my car was fitted with a standard 2.0L Zetec on 40's and had it set to 3psi without any problems or starvation, even on track. Link to comment Share on other sites More sharing options...
Farmer_Terry Posted April 18, 2015 Author Share Posted April 18, 2015 Thanks Guy, that seems like a good place to start.I must admit, while I realised that too much pressure will chuck fuel away, (and before it was fitted that was indeed what happened) the result of too little pressure hadn't occurred to me. Thank you.I will start at 3 and if I get any starvation problems I can increase it.As you may have gathered, I am not very technical with car engines, so is loss of power at high revs the sort of symptom is would be watching for?

Guy Lowe Posted April 18, 2015 Share Posted April 18, 2015 Yes it's like your running out of petrol, spluttering etc. If the pressure is set too low it will happen after a period at high reves when the engine is using most fuel and the carburettor float chambers empty because demand outstrips supply.

OliverSedlacek Posted April 18, 2015 Share Posted April 18, 2015 3 PSI works for me. The float needle valves will cope with a range of pressures, so mostly it's not that critical. Link to comment Share on other sites More sharing options...
Farmer_Terry Posted April 19, 2015 Author Share Posted April 19, 2015 Great. Thanks. That seems to be what I needed to know. Link to comment Share on other sites More sharing options...
