Seeking Sump Plug with 1/8 NPT

Bravo_charlie

I have recently install Race Tech Stepper Gauges and unfortunately I can't get the Oil Temperature to function as I have hook up to a Tee piece at the minute. So I am now seeking a sump plug with 1/8 npt for the sender unit. Any feedback would be very appreciated on where I can purchase one.

Thanks for the reply but I am unsure as I think the sump plug is M12 X 1.75 can anybody correct me.

evocarlos

seams all the other plugs in the block are m12 x 1.75 but without taking the sump plug out and measuring the pitch i can't say

A mate thinks the sump plug is M14X1.5 any feedback on this

evocarlos

your mate is wrong 🙂

Also searching for the part number comes up with the same

edit: probably best off measuring it yourself

Anyone with a part number for the sump plug just to use for reference size.

Bravo_charlie

have fun i tried may places for one but nout i ended up making one from a brass oxy/acct pipe fitting

Bravo_charlie

The quest begins there must be someone who has carried out this mod.

evocarlos

i went to pirtek ,halfords,car parts, and looked on demon tweeks ,ebay and others there is some on ebay but in germany made of stain less and cost 3 times the price they should
there is one place i now know of that may beable to get the adapter
bearing man just up the road from me 🙂 i will ask next time im in there

Bravo_charlie

That will be much appreciated as I have been trying for ages to get the oil temperature gauge to function. I don't mind paying a little extra as long as it works correctly.

evocarlos

im sure when im back at work i could have one or two made up out of brass but will look at mr bearing 1st there prolly only like £6

Bravo_charlie

That would be much appreciated.

evocarlos

i did ask but its not something they can get out of the catalog

Bravo_charlie

Thanks for enquiring its much appreciated. I have been thinking about drilling a hole and welding a adaptor onto the side of the sump so its not sitting to low for speed ramps as I think its the only way that I'm going to carry out this mod.

Bravo_charlie

Would it possible to weld a threaded boss onto the oil sump to enable installation for the oil temperature sender unit. Any feedback would be appreciated

evocarlos

you could prolly drill and tap the sump to 1/8npt and fit a sender with no issues
cant say ive ever thought about monitoring oil temp tho
