Fixed my issue with my 1995 6.5 Turbo Diesel. The sensor seemed legit and well made, and it got me back on the road! It was easy to install, and should give you any troubles. Would recommend 👍🏼

Installed on a 2000 GMC with 6.5td. A pain to get to without the proper wrench or removing the upper intake. After trying every tool that I had and gave up after 1hr + of cursing. I bought a Snap-on crows foot wrench, which only took 5 minutes with proper tool. Snap-On part # S6152

It's made in Mexico like a lot of GM parts are from what I understand.. I think it would be better than buying something offshore if you know what I mean.. and the price was less than I could buy it for wholesale from my local company.. I think locally I have to pay about $80 or so.. sorry Local Company you lost on this one

I have tried aftermarket parts and it seems like sometimes you just got to spend the extra money for OEM quality.

not the quality I expect from ac delco, ran car for 30 minutes and it quit sending oil pressure signal which made computor shut off fuel pump, had to bridge plug for switch to get home getting secound degree burns from headers in the process

To the Amazon customers that answer my question, YOU GUYS ARE AWESOME!!!!Needed to buy a 1 1/16" crows foot to do the job because I didn't want to take the upper intake off to get to it. The symptoms on my truck (98 GMC K2500) was on the highway it ran fine, but in town it would skip and stall. When the oil pressure was high the lift pump ran. When the oil pressure was low the lift pump stop running. When the key is off for more than 10 sec. the ECM triggers the lift pump for 5 sec. then it waits for the truck to start. This switch runs the lift pump when there is oil pressure. Also for $60 I bought a new lift pump shortly after I installed this switch. The pump had 160K on it and for reliability I think $60 is money well spent for piece of mind.

I thought my 6.5 diesel had water in the fuel or issues with the new PMD I installed.While traveling at highway speeds it developed a hiccup - loss of power for a second, This oil pressure indicator solved my issue. - this sensor is also an emergency shut off for the fuel.

This switch dose two things. first tells you the oil pressure. Second is it is a safety fuel shut off. It is common for the second part to fail. A person will assume because you have oil pressure it is working "WRONG". Two wires two functions. one sender, one switch. When the switch part fails the engine will stall under throttle or load. It gets worse as the switch gets worse. sometimes the engine will die. You may think air in lines, PMD failure, plugged return line. Could be anything listed.A bad oil switch or fuel pump can over time can cause damage to the injection pump. A bad switch can work, not work ,work not workOne test is to pay close attention to the engine when you first shut off the engine. You should hear the lift pump or fuel pump run for at least a second or so "the time it takes for the oil pressure to get to low enough for the fuel pump to stop.This is the same noise you here when the glow plug relay is sending power to the fuel pump when starting.

I am updating this review here in October 2014. I have had 2 of these ACDelco D1808A senders, and based on their combined experience I am raising the rating to 4/5.By comparison with a mechanical pressure gauge, I have found that this sender is noticeably more accurate than the BWD equivalent. My experience with reliability has been mixed - one died just as quickly as the BWDs, the other has lasted longer and is still working.I first replaced my factory sender with the ACDelco D1808A (this model). It worked fine, but it only lasted 8 months and about 5K miles. At the time of failure, I was idling at a stop light at normal peak operating temperature. I happened to be looking at the oil pressure gauge when suddenly the needle pegged to maximum, indicating an open circuit. That was it's death - up until that moment it had been working fine.I replaced it with a BWD brand sender with a lifetime warranty. I went through 3 of those senders under warranty. They all died in about the same amount of time as the Delco. But thanks to the warranty, I could replace them for free.So why didn't I just keep using the free BWDs? Because even when "working", the BWDs never really worked properly. They caused bogus low pressure alarms. A mechanical gauge showed that at the high end of the scale they were fine, but when oil pressure dropped into the 20-25psi range, the BWD senders reported 10psi or less. This caused an erroneous "low pressure" warning light to illuminate, and that light is what made those senders unacceptable to me.The BWDs also got progressively more "twitchy" as they aged, while the Delco was more stable (up until death). There wasn't much difference in how long they all lasted before dying (6-9 months).So I went back to the ACDelco D1808A - not because I believed it would last longer, but because it works better. As noted above, my first experience with the D1808A was a failure at 8 months, 5K miles. I'm now on my second Delco D1808A, and it is now 1yr+5 months old and 7K miles. It's still working fine so far. It doesn't sound very impressive but it's significantly longer than the first D1808A or any of the BWDs lasted.What I like about the Delco is that it's accuracy at a hot idle is acceptable for a dashboard gauge. I didn't have a problem with accuracy on either of my D1808A's. Neither of them had any problem with triggering a false alarm on the warning light.Just one added note: If you are worried about your oil pressure, measure it with a mechanical gauge before you panic. Electric senders, even the Delco, should never be assumed accurate, even when new. They serve to get your attention, but should not be used for reliable diagnosis.
