just wondering what the thread size is for the oil pressure sender in the a15?

looking at putting oil pressure gauge in and also would like to keep the oirigianl light operational.

i think that it is 1/8 bsp someone may be able to confirm but i think thats right..

repco sells them, i bought one when i built my turbo a12.

any idea on price? from memory?

Hi guys could someone confirm the thread size for the T piece? is it 1/8?

Cheers,
Tom

1/8 bspt [british standard pipe tapered] similar but different is bspp [british standard pipe parallel] and the US std NPT [national pipe tapered].

1/8 bspt is the one you want.

for reference

Cheers benny! good thing you let me know! i'd just ordered NPT so thank you! a quick call to the guys at namiiss and done! they repacked the order and it's on its way!

Thanks very much! now time to find some nice old gauges!

Just a word of caution with this. I've had the brass T pieces break at the end of the thread many times. It's all down to the weight of the senders at the end of the t piece & the rocking of the engine. Even the extra short one I got from a VW dealer failed in the same way. My solution was to use a braided hose from the oil sender hole out to the inner guard, where I mounted the T piece with senders in place. I just cable tied the T piece to the brake proportioning valve on the Sunny's, but there should be other things you can mount the piece off. I just took a standard sender & the T piece along to a speedway supplier at Seven Hills here in Sydney & they supplied the fitting for the oil pump & made the braided line to the length I had measured. This cost about $30 each time I did it, if I can remember correctly, cheap insurance against breaking the T piece & pumping all the oil out of it.

Wow thanks for the heads up!! Do you happen to have the name of the shop that did the braided hose for you?

Would they make up a super short piece you could literally just have 1cm out of the hole then put the t piece into?

b310gx speaks the truth. Datsun Nationals 2005 .. I think 3 different cars had their brass t-piece fail resulting in oil all over wakefield track. Definitely mount the brass fitting on the bodywork, not the engine.
