Injection Lines for a 4bt Cummins

I've been trying to find a set of injection lines for a 4bt with a p-pump that fit around the stock intercooler because we made our own intake that they will work with. I had found one set from Dieseltuff but the injector end is for 12mm injectors and we are planning on using 14mm injectors. Any help with either a part number or if you could bend them up for me or if you can point me in the right direction of who could bend them up would be greatly appreciated. Really don't want to have to bend them up myself but if that's what it comes to then I will. Thank you

if you have lines that will work, fair valley performance will bend a replica set for you. Depending on your budget, but you can buy straight line and bend them yourself for a lot less. Don’t get soldered on ends, make sure they are swedged

We bend our own lines because no one makes lines For a perkins, it’s not too hard. I make a copy of how I want the line to look with a piece of wire that’s th same length then bend the line to same as the wire

I'm pretty sure (like 99%) Cummins never used an inline pump on the aftercooled engines. All rotary style.
If you do not want to use the smaller injector bodies, you'll need to build, or have the lines built.

The lines that dieseltuff has are genuine cummins. They have 12mm injector ends because they are used for p-pump conversions.

If they have lines bent with 12mm end that will work, buy them and send them out to someone and they will make you a set exactly like them but with 14mm nuts on them. Itd be a pricey way to do things, but it would work

There is also some adapters out there to go from 14mm male to 12mm female. I've got a few around my shop for test equipment. May be an option, just a little tweaking of the lines.
