Fuel lines.

[Reynard38]

I had ordered a bunch of parts for my Westerbeke W13a from Diesel Sqpecialists. The two fuel lines on the engine lift pump to filter, and filter to injection pump) were not readily available. In addition they were crazy expensive, $80 and $100.
I took the old hoses to a local shop that makes all sorts of hoses, brake hydraulic etc. Told them it was for small Diesel engine.
While I waited they made them up for me using the original fittings. Total cost $34.
Just test fit them to the motor. Perfect!

Most times you can save the original fittings. Those banjos or whatever fitting are expensive , durable and last a long time. Typically all that is needed is new hose and copper rings or whatever gasket the End fittings use.

carefully inspect the Banjo Bolt. They are hollow and easily stressed and broken by over torquing . A spare banjo bolt and copper rings are handy spare parts.

Can you use copper with diesel fuel? Thought it was a problem due to the sulphur in diesel.

I dont know the technical answer. Mine are copper for fuel and silver metal, tin ? for steam coolant.

Best ask a pro.

And the banjo gaskets are one time use items. That's why it is a good idea to have a spare or two. Otherwise, they should be annealed before reuse. Congratulations on avoiding unnecessary costs.

Copper crush washers are the industry standard. Not enough fuel in contact long enough to be an issue. I see more aluminum crush washers today than I used to, but I think that is a cost saving issue, not a fuel contamination issue. (I reuse them all the time, if they have been obviously over torqued I replace or anneal them) Copper fuel lines can be problematic for a couple of reasons, the more critical one being work hardening from vibration and ultimate failure (leak).

It would be worth reminding folks how to anneal a copper crush washer........

Wait isn't the term "olive" rather than "crush washer".

[Canoeyawl]

I thought "Olive" was a colloquialism for "banjo"

(You can anneal the copper washer by hanging it on a steel wire (like a coat hanger) as a handle, heating it to a dull red and letting it fool back down. This can be done with small propane torch or even a burner on the stove)

olives are compression fittings for metal pipe

copper washers are washer gaskets for mechanical joints
