Fuel pump assembly is leaking at the fuel return inlet. What to do? What to do? What to do?
After much consideration, decided to use epoxy compound to patch up the leak, because it is known to make a strong bond that becomes very hard. The first attempt didn't work, which could be because a regular 5 minute clear epoxy compound was used and the bonding surface on the plastic was not prepared properly. The most likely culprit is the fact that the fuel line is still pressurised, therefore fuel was weeping out from the hairline crack and prevented the epoxy compound from sticking to the plastic.
So, the return fuel line was disconnected, which resulted in some fuel spilling out. Fortunately a rag came in handy to soak it all up and any remaining fuel just vaporised under the hot sun. Then the plastic bonding surface and crack was carefully sanded with sand paper, followed by rubbing with tissue paper to remove the plastic dust. Finally a 3-ton metal epoxy compound was mixed and applied to the crack and surrounding plastic. The epoxy was left to cure for 24 hours, after which it became rock solid.
Reconnected the fuel line and ran the engine on idle for 10 minutes. No leaks were observed, which is good. Drove the car for another 30 minutes. No leaks observed too. So the epoxy compound patch works and I hope it will last long. Buying a new fuel pump assembly will cost US$ 250, while the epoxy just costs US$ 3.
With Citroen, Peugeot RC HYmotion4 is a field that is increasingly cluttered with hybrid concepts using a new system that can take the road to be unveiled at the Paris Motor Show. Fortunately for Peugeot, they have managed not just recycle or rebadge an existing model, but have incorporated this technology into an boldly attractive four door GT coupe.
Peugeot has joined sister-brand Citroen by releasing a concept vehicle based on the new HYmotion4 AWD hybrid system. The new concept is according to Peugeot, a ‘Touring Car Coupe’ that features a number of engineering and technological ideas expected to make their way, if only gradually, into both of the carmaker’s future production models. Unlike the hybrid systems used by current production vehicles, this concept has no direct mechanical connection between the electric and internal combustion drive systems. This way, the RC can operate in either rear, front, or all-wheel-drive modes. That means it can also operate using internal combustion, electric only or blended mode combining both. Propelling this concept is a rear mounted turbocharged 1.6 liter engine driving the rear wheels and producing 218 hp and 206 lb-ft of torque. Up front, an electric motor provides up to another 132 lb-ft of torque and provides a governed combined production of 313 horsepower. This sort of power pays of with acceleration to 62 mph in a mere 4.4 seconds. The electrons are stored in a lithium-ion battery pack of an as unreleased size, but having the electric motor at the front instead of the rear axle means that more kinetic energy can be recaptured through the regenerative braking process. According to Peugeot, the RC can get 52.3 mpg with a minimum output of just 109 g/km of CO2 emissions. 
Other Hymotion4 concepts in the mix for the future include Peugeot’s Prologue, which previews an upcoming 3008 crossover, as well as the Citroen Hypnos and C4 WRC rally car. These concepts, according to the manufacturer, are a synthesis of ideas that demonstrate a commitment to both respecting the environment and driving pleasure. If all of the technology that is used within this concept lives up to the manufacturer claims, the French may have the inside track in future hybrid production.
