I got mechanical Auto Gauge Oil pressure unit. It came with nylon line which i want to change to a braided line. Now help me out which size should I use.

I was thinking of getting the AN fittings, but i do not know which ones....

The size in the back is 1/4', with the line size ( i might be wrong ) 1/8,

thanks for input

just take it a speed shop that sells the fitting, they should be able to tell you.

also, i hope you aren't running this into the car. if it's a mechanical gauge, it should be mounted under the hood.

What use would it be to me then........... nahh it will be inside!

For the cost of SS line and AN fittings, you might as well return that mechanical OP gauge and buy yourself an electric one. Running wire will be much easier in the end.

Judging from the picture, it looks like a 1/4 PT fitting.

It might just be easier to get the flexible copper line kit that is avil at almost any parts store. like any of the other fittings make sure they are tight and you shouldn't have any problems with leaks

yeah that's wise. the reason it's not suppose to be inside is because you're taking hot oil and running it into the cabin. imagine if you get a leak? or the line breaks while you are driving.

if you want the ricer look i suggest getting an electrical one. it's safer and alot easier to install.

Yeah 2 points towards electric and why i would not get them:

1. I already had electric and the sending unit broke off my block causing me to have the heart attack thinking that i busted my block. Hated that feeling......


2. Electric one do not have a such a big sweep.

So to get it straight electric gauge is non ricer?? While running mechanical gauge is ricer??

Try running a sandwich adapter. That way you can position the sender more upright. That and I have yet to see one break off a sandwich adapter.

If the weight of the sending unit is still an issure to you. Invest in a DEFI OP gauge. They use a really compact sending unit that is about the same size of my thumbtip to first thumb joint. Should you go that route, at least you can feel a bit JDM...

i run a mechanical in my pillar and i run a turbo del sol, i am not a ricer, the gauge uses a crush type fitting not AN style, AN has a tapered end SS wont seal right without the taper

also it looks like a sunpro

correct me if i am wrong

( I know nothing of fitting types) is the crushhing one ( I assume ) since it has a little pin that goes on the line and then it gets crushed and compressed to the line. Now someone sait it is the PT fitting, is there a conversion fitting??

highrev1987

most likely at a speed shop they have a PT to AN

PT stands for Pipe Thread ??

Nicram

What is NPT?? for example

Straight AN Swivel to Male NPT

Chim Chim

PT = pipe thread... There is a taper to the thread itself. You're also hear similar standards such as BSPT, or NPT. As for a compression fittings, it's somewhat similar to a flared fitting. A flared fitting is what you find on your brake system hard lines.

Chim Chim

NPT = national pipe thread
BSPT = Brittish pipe thread

Nicram

so NPT is the PT in US??

Chim Chim

PT and NPT not the same but fairly similar... I believe there is a slight difference in pitch. But not enough that you can't screw a PT fitting into the same sized NPT fitting and vice versa.

PT is what's used here in the states. If you went to your local parts store, they'd probably scratch their head if you asked for NPT fittings...

NPT is what you would normally find on imports. With the exception of subbies. They have BSPT which is like NPT without the taper on the threads... NPT and BSPT have the same thread pitch though...

nice info i smell write up?
