I have replaced an 8" piece of flexible fuel pipe between tank and filter on my Beta 20 3 cylinder. Will I need to bleed it through by hand or is it self bleeding?

If you open the fuel stopcock and bleed the fuel water separator of air as shown in Manufacturer’s literature you might be lucky and get all the air out.
Otherwise follow the “INITIAL STARTUP AND BLEEDING THE SYSTEM” procedure as given in the engine manual
(a) Open fuel bleed screw on injection pump by 1½ turns.
(b) Move hand priming lever on fuel lift pump up and down until fuel with no bubbles comes out of the bleed screw.
(c) Shut/tighten the bleed screw. Clean area thoroughly with tissue paper.
(d) Continue to hand prime for 30 seconds to push fuel through the fuel pump.
(e) Start engine (see normal starting). Note the engine may have to be turned over with the starter for a few seconds before it fires. Do not run the starter for more than 20 seconds. If the engine has not started after 20 seconds then disengage the starter and
continue to hand prime for a further 30 seconds, then repeat.
(f) If engine does not start after 3 attempts then allow 5 minutes for the starter to cool down before repeating (a) to (e).
Note: The starter windings can be burnt out with continuous cranking

Tallon is correct, but you may have to 'crack' the pipe at the top of the injectors to gat every last bit of air out. I had great trouble fully bleeding my Beta 25 and was advised to just open the injectors after the engine is running(but be VERY careful!) to get out the last bit of air. This cured my problem of stopping even after several minutes running.

Thanks both.
