Injection fuel pump

[alga]

Hi all. What is the best fuel pump to use for a fuel injected Zetec engine? There is a Bosch pump used in more than a decade's worth of Audi, VW, BMW, Volvo and other cars (Bosch parts 0 580 254 9xx), is that the one of those? What fittings required, what diameter fuel pipes, tank outlet are best? What about the filter? Thanks!

Ive used a bosch copy found on ebay and it runs fine.

mine is 3/8" 10mm inlet 5/16" 8mm outlet.

Mines on a standard 2.0 zetec.

You need a pump that pushes around 3 BAR, some pumps are designed for higher preasure systems and may overfuel.

i disagree a high pressure pump that is capable of 3 bar or above is fine. the fuel pressure regulator on the end of the fuel injector rail is what sets the pressure.

i got one of these the other day very nice but of kit

Sure the regulator is there for a reason and does a job.

but for example, a pump designed for a K-Jetronic application with mechanical injection is likly to put out 7-8 Bar. Where as the L-Jet based applications (on which the EEC-IV/V is based) is more likly to need arround 3 Bar max.

Best to try an match the pump to a similar application rather than just buying anything. If you have too much flow, and too much pressure then the system won't be able to return the flow.

Sorry to disagree, but I converted a Capri to EEC-IV with and engine and gubbins from a granada (pinto) and used the tank and fuel pump from a 2.8i capri (K-jet) and it ran for 5 years no problems whatsoever. Believe the guy I sold it to still runs it regularly.

the only thing i can think of at the mo is to make sure you have a strainer before the pump as all in tank ones have one fitted at the pump and external ones have one in the tank to catch the bits befor thay trash the pump.
