The pressure is constant between the pump and the cold start valve . The higher pressure won't make it run rich but it causes vapour lock in hot weather .The return valve wont cause a high reading though unless you have a blockage. Crushed fuel lines under the car are common where someone has lifted the car on a two post and lifted under the floor.
if you have touched the plunger elements with bare fingers there is every chance they are marked now ,and you can't really set them by guess work . The rack is worked by the governor via the cold start and cold running links ,any maladjustment there will affect the running,hence the need to get them set up on the test bench. As i mentioned before there is a oil pressure seal which lubricates the plungers but also prevents fuel leaking into the base of the pump and then into the engine where it does a great job of wearing everything out.
if there is a lot of petrol smelling oil in the governor case you need to get the pump rebuilt . A governor floating liquid makes the pump slow to operate .
The pump i have is still on the engine, which was removed from a car because some clown had bolted a manual flywheel on and the imbalance wrecked the crank and the block. The rest of the engine is OK. You are welcome to come over and have a look ,I'm at rocklea,ph 0402413373.
