brian in buddina Posted 5January, 2021 Report Share Posted 5January, 2021 The insulated cover on the fuel rail on 944 is it decorative or functional? Not sure what the 924 or 968 has/had. A discussion on a 944 fb page is saying decorative by consensus. I didn’t think Porsche in the 1980s was into decor. Opinions are easy but anyone know the truth?

Peter M Posted 5January, 2021 Report Share Posted 5January, 2021 Brian, For it to be effective wouldn't it have to fully enclose the fuel rail? My votes for "decorative" to match the shape of the cam cover and intake manifold. Quote Link to comment Share on other sites More sharing options...
Stepo Posted 5January, 2021 Report Share Posted 5January, 2021 The truth should be known, would it be rude to call out to our local guru? @Buchanan Automotive brian in buddina 1 Quote Link to comment Share on other sites More sharing options...
Redracn Posted 5January, 2021 Report Share Posted 5January, 2021 It’s functional even if only by a fleas nat of nothing a proper heat wrap would be much better. Heat pickup by the fuel rail or fuel lines or anything else including heat generated by the fuel pump is a major issue and fuel temperatures of over 50C are very problematic. The lower the tank gets the bigger the problem as less fuel to absorb the heat. Moral of the story is don’t expect to climb a mountain on a hot day with not much fuel in the tank. It will get hot and boil in the tank at the fuel pump inlet at the lower atomespheric pressure. brian in buddina 1 Quote Link to comment Share on other sites More sharing options...
