pressure gauge.
5. Connect adaptor LRT-19-010 and pressure
gauge LRT-19-004 to manifold and fuel pipe.
6. Connect battery earth lead.
7. Start engine. Pressure at idle = 3.5 bar ± 0.2
bar.
8. Release clip, disconnect and plug fuel pressure
regulator vacuum hose.
9. Start engine. Pressure at idle = 3.0 bar ± 0.2
bar.
10. Stop engine. If pressure is out of tolerance
suspect the following in order: fuel hoses,
regulator, filter and pump.
11. Remove plug, reconnect vacuum hose and
secure hose with clip.
12. Disconnect battery earth lead.
13. Disconnect pressure gauge LRT-19-004 and
adaptor LRT-19-010 from fuel pipe and
manifold.
14. Disconnect adaptor LRT-19-010 from LRT-19-004
