S1 fuel pump with integral non return valve
Discussion
To continue the saga of the S1 restart problem, which has been mooted to be a leaky non return valve on the fuel pump, . . . I was advised by some of you guys that the answer may lie in a new fuel pump with an integral non return valve.
Martin from TGA in Wolverhampton has carried out a search and the pumps that are available to him are not guaranteed to have a non-return valve fitted.
Obviously to pay out for a fuel pump that is of no use is not sensbile. So is there any advice as to where to source the correct fuel pump with integral non return valve, or is there an alternative installation which will protect the system and eliminate this starting problem.

Yep, bloody frustrating (at times) these S1s. When I broke down in Stoke on Trent in November . . . . which turned out to be the fuel pump relay - well diagnosed from a distance Glenn Robbo! . . . the breakdown guy (one of the old school mechanics) tested various things and definately had fuel getting through to the pump. We're now considering getting the pump (? - sometimes I don't get fully included in conversations) pressure tested. Looks like we could be in for a new fuel pump and adding a filter.
A bit of history from the car's documentation file that might throw some light on what has gone on: the car appears to have had fairly regular use from new until 1996 (evidence mileage and MOTs). In 2006, the car had a new owner and appears to have had problems - one of the invoices states that the car had been off the road for 10 years. Among the invoices for 2006 and 2007 are evidence that a new fuel pump, a fuel pump relay and a relay yellow pin were fitted in August 2006, in October 2006 another fuel pump fuel was fitted along with a "start" valve, in November there was an Injector test + clean; injector O ring k-jet; Bosch fuel filter,Bosch fuel accumulator, test/clean fuel injectors, fit new O rings. April 2007 - Engine flooding; fit supplied 2nd hand metering head, adjust throttle butterfly - at this point the car didn't have an MOT and was still off the road. The car passed an MOT in May 2007 and then had a Fuel sender; sender seal; fuel sender lock ring fitted at the end of the month. The car was sold the following year and then sat in a private collection for 6 years, covering only 144 miles until I bought the car in 2014.
We had a lot of problems in 2014 with hot starts (among other things)and used a fuel additive most of the time, since then fuel additive has gone in every other fill. 2015 the injectors were cleaned and rebuilt and things improved, early 2016 I had a starter motor fire and lost some of the wiring, then had major problems with the alarm system and power drain during starting. The alarm was removed and a hot start mod fitted, but the problems persisted, just before Christmas the car had an overhaul of the wiring which improved a lot of things, but not the repeat start problem.
Just writing this I can see that this car has a history of being a "little madam".
