Worried about a gas leak catching your car on fire? how about this...
 

I am currently replacing my FPR and FPD so it got me thinking. Since these things fail and cause an extremely hazardous gas leak onto the engine, why not get something that tells me if there is fuel spraying onto the hot parts of my engine?
After a little bit of searching I came across this gas detector

How could we rig up something like this detector, I have seen gas detectors that are “explosion” proof so I would assume that they can handle being up there with plastic solenoids. Something like that would be extremely valuable in a fuel leak situation. Let me know what you all think and hopefully we can work something out that stops our precious cars from burning to the ground. It really makes me sad to see “My 7 burned while I watched” threads.

Thanks, Jason

Seems like a great idea but I would imagine they would be way to sensitive to work under the hood of a car. They detect in the PPM (Parts Per Million) range. I would imagine the sensor would be going off even when fuel wasn't leaking.

They can be adjusted to fit any application I would believe. If this proves a good way to do it im sure we could contact the company and direct them in the production of a new product if there is a big interest in it.


Edit: some of these look very promising.

Man, with that kind of paranoia, it's a wonder you can make yourself get out of bed in the morning.....sounds like you've been watching Dateline too much or something. :)

Hahaha it was just a thought, I think a gas leak gauge would be more useful than a narrowband A/F gauge. Im not paranoid, just trying to think of new things. I think someone fears change :) thanks for the laugh, I needed one while studying for this religion test.

^^Haha! Yep, Why not just check and pay attention to your fuel system pariodicaly and fix as needed. Or here is the best preventative, sell or don't drive the car and you won't have to worry about it catching on fire.

I said what Rynberg said a few times, Almost all the issues are "self-inflicted paranoia". If you or the mechanic did their job correctly, you should not have anything to woory about for a looong time. These things just don't decide to leak because they are in a bad mood. That is due to old hoses and associated pieces of the fuel system. Which, reverting back to my previous comment, If it were inspected and fixed properly, there is nothing to worry about.

Perhaps he fears wasting time and money even more... :D

do you work for microsoft?

you invented an extremely complex solution for a very simple problem

yea because watching my car burn and then rebuild it all the way is a simple problem. Come on guys think a bit here dont just reject an idea because it is new. Would you not agree with me that fuel leaking is a fairly common problem with our giant injectors and fuel pulse dampers. Why not install a small thing that will tell you if there is a pool of fuel sitting on top of your engine?

Edit: I am not paranoid of my car burning to the ground, im just trying to think constructively here.

I think it's a cool idea - go for it and see if you can get any more info/ideas going for an installation.

We're not rejecting it because it's new, we're rejecting it because it's a bit silly.

Fuel leaking is NOT a common problem with regular maintenance. If the fuel system is installed properly, the fuel pressure dampener and other parts should last for several years with no maintenance required.

So, on the one in several thousand chance that you could somehow randomly spring a fuel leak, you want to install ANOTHER OBJECT under the UIM (crowded enough already, don't you think?) and then place yet ANOTHER warning light/LED in the passenger cabin, in a place where you'll actually notice it if it lights up/goes off? I don't know about you, but I've already got more than enough little electronic boxes and doo-dads in my interior already.

Like I said half-jokingly before, if you going to go through life living in that state of fear, a burned engine bay is not your biggest problem...
