Fuel Pressure

[richd]

Got my 2.0 ZETEC (WEBER 45s) throught the registration gubbins the week before SVA, had to move away to work, put it up on props and there it stayed until 3 weeks ago. Passed the MOT no problems, but in those passing years have forgotten most things, not that i ever knew much in the first place.

Had a missfire, so took it to "PowerStation" (lottery winners only should go).

The verdict : fuel pressure too high, fuel was coming out of the Webers. It had a pressure of 6.5 psi, and was told that it should be 4psi. Do you think that this is my only problem (as far as the petrol is concerned) or should i be looking further? Can you recommend a pressure regulator to use, and where to buy it from (apart from the dreaded DTs).

Also i have YOKOHAMA "A520"  205/50 on 16" rim and can't remember the tyre pressures

Many thanks

Hello Rich

Regarding fuel pressure 6.5psi does sound way too high for weber carbs. The set up I have on my car is a purolator chrome dial type of regulator - easy to set up as the dial is calibrated & you just set it to the pressure you want - I would have thought 2.5 - 3 psi should be bang on - thats what mine's set to (admittedly mine's a xflow running twin 40s). Got mine from DT & was about £20 I think

This is something you should not leave as raw fuel washing down the bores can cause glazed bores - head off job to fix.

Hope this helps
