Make sure the Gauze filter under the tap is clean!!!
On the top of each filter is a screw. Not the bigger bolt.
slacken each screw about 2 turns.
Pump the
fuel hand pump until fuel with no bubbles comes out.Then tighten while slowly pumping to stop any air getting back in.
(The hand pump is the round "wheel" under the main injector pump, unscrew it and then pull it in and out to pump.)
Then look at the top of the Injector pump where the 4 pipes come out to go to the injectors. At the front of the pump is a hex bolt, usually with a screw slot, may be painted red, 12 mm spanner I think, slacken this one and again hand pump until fuel with no bubbles comes out. Then tighten.
Crystals will normally start after 15-20 seconds of starter after this.
occasionally,although I have never known a crystal to need it, you may have to slacken Injector pipes where they join the injectors behind the inlet manifold and let air out while cranking.
Hope this somewhat rambling answer helps. Dave
