|
| Hello everyone. I bought a 67 squareback 2 weeks ago and I have a couple questions. I need to check/adjust my fuel pressure. How do I remove and change the gaskets on the manual fuel pump on top of the engine? Also I have been reading up on ignition timing procedure. It talks about disconnecting vacuum lines. Since I have electronic ignition do I need to worry about this? I dont see any vacuum lines on my engine. Not to say they shouldnt be there. But I am trying to correct previous owners mistakes. Also do I time it when it is at idle or at 3400 rpms or both. Thank you |

Welcome!
Take some pics and pull part numbers off your carbs and distributor.
Answers vary depending on that you have, especially since it is no longer stock. |

the gaskets are under the pump itself, you can add or subtract gaskets to get the pressure you need. You can use a cereal box for cutting gaskets a little thicker. I have had to use 2 or 3 thick gaskets to get down to the 2.5-3psi range with some pumps.
sounds like you have a mechanical advance distributor, so you will just need to set the max advance at 3400rpm to 28-30 degrees and let the idle fall where it will.

2.5-3.0 lbs of pressure is plenty for that set up.
