[QUOTE="Mark Space-Ratio, post: 303093, member: 14370"] On my first van I had a leak in a braided fuel line connecting to the fuel pump. I experienced an overwhelming smell of petrol, luckily I was stationary and about to drive off. I found that although the pipe looked decent the braid was soaked with petrol and initially not easy to spot. I stripped off the braid and found that the rubber had cracked all along the line but not quite enough to leak everywhere but just at one point. These were original lines so I replaced them with modern rubber pipe where the braid is sandwiched between the rubber for strain relief. I don't trust aftermarket braided pipe as they are thin and quality is questionable. I actually bought some braided and thought it was rubbish when it arrived so now just keep that in my spares box in the van just in case. They are also sold in different internal diameters so they need to be correct for the pump and steel pipe from the tank that they are connecting to, it must be a tight push fit. Whilst your mechanic is fitting the new pump get him to assess your fuel lines and see whether he thinks they will last. Rubber loses its elasticity in the heated engine bay environment. If you have the rubber T piece attached to the engine bay roof and two steel pipes running off up to each outside air intake then it is worth getting the rubber T piece checked too. This is a breather pipe for the tank and maybe fitted to your '72, it was on my early '73. This is also a source of fumes if a failure. Good luck Mark [/QUOTE]
