    making an adapter for the oil pressure sender

    post part 1

    I'm making this for a member on here, so I thought I would make a technical post of it.
    This is an adapter that will mount on the firewall, this allows oil pressure from the warning switch port, to travel to the firewall, a warning switch sender to screw in, then on to the gauge in the car. It's made from 3/4 bar stock aluminum

    I found center already on one end on the turret lathe, this is drilling out the oil passage that runs through it

    squaring the ends on the bridgeport

    finding center

    marking the center hole and holes for the screws

    holes center punched

    holes drilled

    screw holes counter bored

    POST PART 2

    I use the drill press to start the tap by hand, to make sure it's square


    finishing tapping the threads

    adapter and pipe thread plugs for pressure testing

    pressure testing at 130 psi

    finished part, mounts to firewall and warning light switch screws in

    this is how it would connect at the oil filter, the only difference is there would be an adapter between the fitting you see here and the oil filter housing

    this is how the other end would go at the firewall side, the line to the oil pressure gauge comes out the other side.

    Ok useful info, if you change your oil pressure sender over to retain the gauge and warning light, you can use one from an MG, here's one link, they are all over ebay for around 5 bucks. they come on at a higher pressure then 3 psi, and they are a single wire just like factory. should be the same for any MG, or MGB or sprite. I think this is what I used. rock auto has one like it too, just order for the sender for any year MG, should be around five dollars too. http://cgi.ebay.com/ebaymotors/MG-MI...sQ5fLiterature

    Re: making an adapter for the oil pressure sender

    i'm going to possibly start making them, 45 bucks including shipping. I might break even at that rate. thats including the 30 percent discount for three geez members. these are hand made and take some time to make each one, I don't exactly have a CNC machine or anything. that includes the hose which i have a limited supply of, and one 90 degree -4 to AN fitting. one straight -4 to AN fitting, and the high quality brass fitting for copper line to the gauge. I may have to go up in price though, I sold the first one for that price, I just about break even. prototype first parts are always cheaper. I can make them with 1/8 npt for the warning light sender, or 1/8 bsp to fit the factory sender.

    I'm planning on doing both. Run the line off of the filter base to the distribution block on the firewall, with the factory sender on one side, and the pressure gauge fitting on the other. Where do you get BSP taps, anyway? And what do you gauge the threads to, 3-5 turns standoff hand tight?

    Edit: I see you have a sensitive quill on that bridgeport. You should be able to drill and power tap the holes in one setup with that.

    yea i normally would, but it was in use, i just drill the holes normally with an R, then I use a pipe thread reamer, and hand tap them. as far as the BSP tap, I got it from MSC industrial supply, it was backorderd for six months while I waited on it, I just drill and tap and use a 1/8 pipe thread ramer just like 1/8 NPT, the only difference is the BSP has 1 extra thread per inch
