Hi everyone. I'm wanting to connect a filter/regulator to my Hif38. As you can see from the pictures the only real place I could fix the filter was on the opposite side of the fuel intake for the carb. How do I connect '1' to '2' together correctly? Can I cut the hard line at '3' near the carb, and just feed the hose across from '1' and attach it to that? It would be facing in the right direction so looks straight forward. Cheers, Daz.

It's only a solid metal pipe to keep it from falling on to the exhaust. You can just use a length of hose if you keep it away from the melty bits.

Thanks Ethel. I've not bought the hose yet so don't have a feel of how it will work, but will it bend back on itself without kinking at the carb input?

If you allow enough length to complete the full radius of the turn for that thickness of tubing then yes, that radius will vary depending on wall thickness, tube diameter, strength of material etc

That is another benefit of the hardline though, you curve it to the right shape with the right tool and if its not kinked then, it never will be in future

Cheers Stu. What tool do you use for bending?

Use 1 of these.

I am sure you can get them in the UK, or they should be available from Amazon.

Hose won't kink unless you force it in to a tight enough bend. As I said, the factory used a rigid metal pipe because it runs from the mechanical pump past the exhaust manifold under the carb. From where you have your regulator the most direct routes are over the inlet manifold or along the  bulkhead. A decent hose radius would accommodate the movement of the engine on its mountings. A pipe would add another 2 joins in the line & reduce the  length of hose that will need to do any required flexing.
