Xnke Posted November 23, 2008 Share Posted November 23, 2008 Does anyone here know if the S130 oil pressure sender (with the pressure switch to cut off an electric fuel pump if there is no oil pressure) will work with the stock S30 gauges? If so, could this be used as a safety switch for said electric fuel pump? Quote Link to comment Share on other sites More sharing options...
loy Posted November 24, 2008 Share Posted November 24, 2008 Yes it'll work with the stock oil pressure gauge. I don't know about having it as a safety device, possibly with a relay it'll work. Quote Link to comment Share on other sites More sharing options...
josh817 Posted November 24, 2008 Share Posted November 24, 2008 You can buy a T splitter thing to screw into the block and then it splits for the sending unit to the gauge. Then the other end you put to a 1/8" fitting or something to screw in a warning light. You can buy them for different pressures for instance a VW bug has like 2-3 psi switch. The 2 prong ones use a 12v power source from the light and then the other prong for the block. You can buy 3 prong ones which have the same but the 3rd prong is to cutoff whatever you want when oil pressure drops below the given point. I don't think I'd get fuel pump cutoff though because if you're using lets just say a set of carbs that don't have accelerator pumps so when you press on the pedal it doesn't shoot gas in, how will you have pressure to start up the motor without the pump running? That sort of thing I do suppose. That is... if we're talking about a sending unit AND a low oil pressure warning light. Its on my list of things to do. :] Quote Link to comment Share on other sites More sharing options...
dano Posted December 7, 2008 Share Posted December 7, 2008 Wow thanks Xnke for posting this. I had the exact same question a few days ago. I'm now planning on upgrading to the zx sender so I can use the cutoff functionality for my elect fuel pump. One of the arguments I heard in favor of using a cutoff sensor is that in the event of a bad accident you don't want the pump to continue sending fuel into the hot engine bay and potentially having it spread everywhere. Now I have no ideas if this is a likely scenario. At the same time though it's not a tricky mod and it could save your life. Which is why it's high on my to do list. YMMV.
