Replace metal fuel lines 4Bta

[youngfam]

Hello looking to replace metal low pressure lines on 2001 bayliner 3488 with 4bta. Cummins says return lines no longer available. I see kits here for 6bta but no 4bta line kits. Any suggestions for new lines and connections?thank you

replace metal fuel lines 4 BTA

Sorry for the delay Pics attached of the two metal lines on my 2001 Cummins 4BTA.  I am interested in improving the system for some peace of mind. The one line you see with the hose spliced and clamped was one that had a hole the first year and a marine mechanic fixed to save the summer trip. The other line next to it, last year came apart at the connection and filled the bilge with diesel. Cummins said the line that has the hose spliced in is no longer available.

Options?

 

Thanks

Rob

I have 4BTAs also. Last summer the return line broke right at the #1 injector on the front side. I tried everyplace I could think of to find a new return manifold using the Cummins number. It is NLA! I took the line down to my local hydraulic shop and they brazed a hose barb onto the banjo fitting and another to the other banjo fitting by the overflow valve. If you have it broken in any other spot you can get individual banjo/hose barb fittings and use fuel line to connect it all with t fittings. Where did yours break?

Most of the steel fuel lines have a “tag” on them.  The tag is a flat piece of metal that is bent around the steel line at some point.  They are about an inch long or so.  This tag has a number stamped on it to identify the specific line that it is.

Not sure if the return line has a tag but try and look.  These tags are painted with the engine so they may not stand out unless you are looking right at them.

I posted an example
