YNY530H Dennis F43 WrT GlamorganYNY 530H was purchased by the old Glamorgan County Fire Service in 1970, and is believed to be the last petrol appliance purchased. It is powered by a Rolls Royce B81, eight cylinder petrol engine and an Allison automatic gearbox.
In 1974 under the then Mid Glamorgan Fire Service, following the local government re-organisation, it was to serve at Pontypridd and later at Pontyclum, Abercynon, and finally at Pontycymmer. From 1984 it was preserved by the brigade before being sold to the A.D.T. Auctions, (now B.C.A.) at Newport in December 1992. Its new owners Parkway Commercials of London then sold it to Fire Aid, Early in 1995, following which it was donated to W.A.F.E.R.S. by Simon Rowley in 1998.

The transition seemed to take hold in the later 60s and 70s, as more powerful Diesel engines became available in less expensive fire appliance chassis, not least the 170 BHP Perkins 510 V8.
This was available in Dennis, Dodge, ERF, Ford and Shelvoke chassis - and some of these manufacturers also offered quite powerful turbocharged six cylinder diesel engines around 140 BHP too…
I personally think one stimulus was the fact that for many years after 1959 Merryweather insisted on supplying their very popular new hydraulic turntable ladder exclusively on the diesel powered AEC chassis with the AV 470 engine, so many petrol-only fleets ended up with one or more diesels in their mix. They then found that this diesel performed quite adequately and was extremely reliable in addition to being much more economical.
After our first sale of eleven petrol powered D series to Gloucestershire in 1967, Ford sold only diesels to around thirty brigades in the following years. These either a regular 360 six, a 300 turbo six or the 510 Perkins V8, with 130, 140 or 170 BHP respectively.
