"How to" request: electronic oil pressure guage install

[khaosman]

Mine was over 6 ft...

Total, I assume, but I mean for just the short part (from the block to the splitter/senders).

Less than a foot.. but don't start with the correct length, No doubt you will have to cut it a couple of times to get the ends on unless you have done them before. They are a pain in the butt..

Jason... good post! How long was the hose you used, about a foot? It doesn't appear to necessitate being very long.

honestly i can't remember. It was right about at a foot i think. All we did was hold up a piece of small flexible tubing stuff we had laying around to judge, then measured what we figured was nessesary. I think the hose was ~$15?? Not bad. It was alot easier to deal with than the hoses from summit, at least for me. I've never dealt with braided hoses or hose ends before though, so it was much easier to have a shop do it.

EDIT: also worth noting, because of the angle i mounted all my stuff, having a built in right angle on the hose lessened the nessesary length. If it was a straight hose you'd have to allow more space for some gentle curvature.

Would this work?

Male tee off of block
stock sending unit on one side of tee
Straight female one the other side
BSPT Male x NPT Female adaptor connected to the Straight female

those aren't in the parts list that livelyjay posted. He had in mind a direct connection, but a remote setup is a much better idea if you're going to use the stock sender in addition to the aftermarket unit, since there would be a ton of mass hanging off of one threaded joint if you didn't remote mount it.

I got my 1/8 NPT to -4AN lines from summit racing. IIRC they weren't too hard to find, just make sure you get the specified male and female ends i talked about in my writeup.

i'm not sure whether you could pull that off or not. In theory it does seem like it would work, although its STILL the best idea to remote mount, due to the extra weight.... but that point aside, i'm not sure theres really room up there for all that stuff. And you don't nessesarily have much room to maneuver it around, since your tee governs which direction the other stuff goes and your tee has to be tight. I would still reccomend remote mounting it, although if you really don't want to you could try this and it MIGHT work.

I talked to my dad this afternoon who uses these fittings in boiler repairs all the time and he also says that the weight might be too much. He said that is there is enough pipe to thread into it would hold...but.... I think I will go remote mount also.

cool. Yeah with something thats A) hanging directly out of your block, and B) carrying oil, if something goes wrong with it that could be QUITE bad.

Awesome Posts guys! Thank you so much for the help. It looks like I won't get to it this weekend, but I should be able to tackle it in the near future.

Just as a clarify, you all used a -4an oil line? Is that correct? Or did you use a -6an?

Thanks again!

 

[jmv]

i used -4AN, not sure about others.

 

[Maestrokneer]

Cool....thanks jmv

 

[jmv]

anytime!

BSPT fittings are the work of the devil. That is all. I think I am going to have an oil-filter sandwich plate thing overnighted to me (yupnope)

 

[khaosman]

I found a site with lots of BSP stuff http://www.pegasusautoracing.com/group.asp?GroupID=PLUMADAPTBSP

They don't appear to be tapered though. Think it'd work good with a crush washer and some teflon paste?

i dunno, i just used the stuff from livelyjay's list which i linked in my earlier post, except for the one fitting right off of the block. The one i got seemed to leak, so i stopped by a 'speed shop' and they carried that piece since apparently nissans and a few others use that too

 

[khaosman]

I found a GREAT how-to thread on honda-tech about this very subject. Check it out: http://honda-tech.com/zerothread?id=377208&postid=6785467#6785467

Good to know I contributed in some way to the forum.

What was the problem with the fitting you bought? I know Nissan's and most Japanese cars use BSPT fittings for the oil. Just wondering if maybe I need to update my posts.

i just couldn't get it to completely seal. I put the tape sealant on all the threads but it kept slowly leaking. I grabbed a part from a local place and it seemed to seal okay. I dunno??

Agreed. Speaking from experience it was bad. I had a similar setup, and the brass fitting broke of (after about a year and a half). Half of the fitting was still stuck in the block. Oil got all over the inderside of the car from the engine to the muffler. I ended up getting the stuck portion out, but the stock sender didn't fit well after that. Ended up getting it fixed by the dealer. Just words of caution.

I found another option for connecting gauges to the stock pressure sender location and it has been added to my list on Post #16
