the problem started the other day and I live in a mountainous region of western Canada. When I started up the hill normally I can get it upto or beyond 70 mph at the top but this time it went up at 30. When I got to the bottom of the hill I popped the hood and looked into my (after market) racor filter bowl and all I saw was fine bubbles and I mean lots. This was at idle too! My racor is getting positive pressure as it is between the lift pump and the injection pump so I know that's not the problem. My question is, would the return line be the most likely to give me the problem or the feed line from the tank?
Also I have seen the numerous transitions from braided to solid lines going to the tank which looks like a nightmare to replace. So would it be best to replace the whole line back to the tank and how easy is that?

thanks

Replace both lines (supply and return) with diesel rated fuel hose - not the standard fuel hose you get at your local NAPA dealer...

If you cant find suitable hose in Squamish - you can order a kit from here:

In addition to the hoses, both on top of the fuel tank and in the engine compartment, check the electrical connection on the fuel heater. They are known to get cracks in the insulation and leak air. Also, check your fuel/water separator and its seal, and the seals and screen in the fuel heater. Some 95's came with a one piece overflow valve, so check that and change it to a two piece if you happen to have the older style. If the overflow valve is good, a crack in a return line would not cause any problem, other than losing fuel.
