Fuel pump for a 1977 Silver Shadow II

Hello, I have a Rolls Royce Silver Shadow II 1977 with, as I understand, a twin pump that sits a short distance in from the right rear tire seen. The problem I have is that it does not seem to work. Last year the car was started after standing still for approximately seven years in a heated garage. The car would not start at the beginning, after many attempts. Got the tip to buy a battery with more amp-hours which solved the problem and the petrol pump started to buzz when the key was on the RUN. When I later turned to its starting position, then pull the starter, the car started running. I then drove the car to two weddings which worked great except that the idle was too low at times when the engine stopped the instance. red light. Got to run some with the left foot on the brake and right on the gas while braking into a longer distance and the engine went into the yard, not really easy. Have long suspected that the petrol pump is not able to send up the petrol. Have noticed that it is only occasionally I can hear the petrol pump after I put the key in RUN mode. Most recently when I started the car th petrol pump worked maybe after 7-8 tests when turning the key. Then it was a gurgling sound and it sounded like it was uneven. We got the car under its own power out of the garage with some engine failure but after about 200-300m it just stopped. Now it wont start at all. The starter motor works well and the car sounds alert except that it does not start, of course. We have two paralell 12V 95Ah batteries in order to assure ourselves that there is power on the battery. Even tried a little tap on the petrol pump to no avail. Checked fuses. Have also suspect that there might be problems with voltage up to the pump. I would be very grateful if anyone knows how I should proceed or have any tips. And maybe if the pump is broken, were do I get a new one, and can I install this myself if I am reasonably handy. Do I have lack of power to the pump.
PS. Can you tow the car in neutral without the gearbox taking the rap. What to consider when towing.

Ps. Excuse my bad English

Expectant greetings

the shadow has two fuel pumps in parallel, so if one fails you won't notice anything. but when number 2 fails the car will run out of gas. I occasionaly have a mechanic test the pumps by disconnecting the output fuel lines from the pumps
one at a time a check if they are both working.

The pumps are easy to remove, the only problem is the car has to be lifted to get at them

Please follow the link in my previous posting. It includes more information about the fuel pump(s) and why they may not feed fuel to the engine.

A copy of 'The Shadow Owner's Companion' by Jon J Waples is always useful for the DIY Shadow enthusiast.

my 1978 Rolls Silver Shadow II trunk will NOT lock. no activity at the locking mechanism. Does the Rolls SS II trunk work as a Mercedes ? in that it sucks the trunk down into the lock position ? I can roll the gear system, but the trunk will not engage and lock. Any ideas how to get the trunk lock to work ? Many thanks

No, the SS2 doesn't work the same way as the Merc. What can happen is that the locking pawl can be moved into the locked position while the trunk lid is open so that the lid catch just bounces off it. The cure is to locate the little lever that opens it up again. A few drops of light machine oil or even WD40 can get things moving again.
