dipstick tube size

[5.9 Cummins Fan]

Long story short I cracked my dipstick tube (brittle plastic). Does anyone know the inside diameter of the tube? Looks like I could use nylon air brake line to replace it cheaper than buying a new tube. Thanks in advance

By my eyeball, I would venture a guess around 3/8". No way of measuring any pieces left from yours?

 

[5.9 Cummins Fan]

Yeah I can measure, but forgot to before I left the shop. Didn't want to make two trips but oh well. I will stop and grab some 3/8 and see if it will work. Pretty cheap stuff, will post if it works. I can't be the only person Murphy's law applies to when doing a simple starter replacement.

I can look here in a little bit, mines over at the shop.

.375 is the outside diameter of the metal tube in the block.

Snedge is the man! Thank you I really appreciate it

1/2 OD air tubing works perfect. .378 ID

 

[Knoberman]

Good to know. Thanks.

Pushed right on nice and tight with a little grey permatex. Looks factory, cost a whopping $3.27

Hey, my eyeballs work pretty good!! Good to know the air line worked.

Thanks, Jeff!

Does the dipstick handle seal well on the air line?

 

[Snedge]

The dipstick end also has a metal insert.

 

[5.9 Cummins Fan]

Yeah the dipstick seals on the metal insert. Just tubing in between them
