2G Fuel hanger identification

[jpmxrider489]

I recently bought a extra hanger and I have never see this before previously. If someone can help me out here. Can I plug the hole? Use it for a larger feed/return? Then I can cap the oem feed. I just dont know how it would fit in tank. Mainly just need identification. I'm talking about the hole with the two studs.

that looks like its for a fuel vapor sensor. what year did that come off of? I don't think they started putting vapor sensors on until 2003

My 99 GST has one. It's for the

Fuel Tank Differential Pressure Sensor - Mitsubishi (MD322973)​

and was on the 98-99 turbos.

That's what I was guessing but couldn't find pictures of one assembled. I saw a hanger listed on ebay as 95-97 which was odd but all the 98-99 looked the same. I guess I need to find that sensor to plug that hole. Thanks

Going to be pricey for a new one: https://www.mitsubishipartsnow.com/oem-parts/mitsubishi-fuel-tank-pressure-sensor-md322973

Wow, definitely not buying one just to plug a hole. I actually don't need it. Any ideas to plug it? I might try and just use that hole as a feed line and cap the factory one.

Only a guess but maybe put a bolt through it (from bottom up) installed with some kind of gasoline sealant? It's going to have to be air tight to pass the gas tank vacuum testing the system does when it tests for leaks if you care. Of course without the sensor I suppose that's a moot point and you may get a P0450 CEL anyway if you have a 98-99.

Thanks for the input. I actually don't know of a gas/ethanol sealant to use. The bolt idea is good. Ill probably try that.

I just today found a "fuel resistant" "Gasket Dressing & Sealant" made by Permatex (#85420) at Advanced Auto Parts you might try. Suggest using a stainless steel bolt/washer installed head down (inside tank)..

 

[jpmxrider489]

Thanks for the part number. So when using bulkheads, I assume that sealant should also be used? I wondered why I have a gas smell and have stat o seals and rubber washers to help but to no resolve.

For that gas tank cover, the main large factory rubber gasket MB400461 (same diameter as cover and has rubber pegs that fit into cover to hold it on straight) w/o sealant is what is used. You put some soapy water on it upon installation (FSM specifies) and I've had no problem doing it that way (of course my rubber gasket was in great condition). I'm just guessing about using the sealant as I'm going to try it on a fuel fitting leak on my motorcycle and thought perhaps it may work on your bolt idea.

 

[jpmxrider489]

Sounds good. Thanks for the input.

I put some of that sealant on a piece of paper and let it dry over night. It's blue and remains sticky like gum. Then I put some gasoline on it and it seems to handle it ok. I wouldn't emerse it in gasoline all the time but for sealing that bolt in the cover I'd think it would work good. Don't use it to seal the entire cover though - only use the factory rubber gasket w/o any sealant. It appears to be used for a permanent seal and is way too sticky for sealing the cover (you'd never get the cover off w/o destroying any rubber gasket and probably never get the sealant off either).

Good info. Thanks.
