Help identifying hose spraying air and fuel?

Started my 2019 Tacoma 4WD this morning for the first time in over 2 weeks since we were out of town. Battery was dead so I had the hood open, thankfully!
When it started I noticed a ton of mist spraying up from the engine bay on the right side. Upon turning off the truck and investigating, I immediately smelled gas.
Unfortunately it looks like there’s squirrel/rodent damage on a small hose. Can someone help me identify this hose? Any advice on how to replace this hose? Attaching images.Thanks for any help!

 

Contact a Toyota Dealer, just received a letter 23TE01 about a fuel seepage odor around high fuel pump 10 years from first usage.

 

Looks like the (low pressure) feed from the fuel tank, it goes to that high-pressure pump sitting on top of the engine.

 

I think it called no.2 fuel tube sub-assembly.
Need to take the intake off to replace.

 

good catch! That could have went bad fast!

 

Definitely! Had the potential to go way south pretty quick. Good luck on getting that line repaired.

 

I almost hate to suggest this, but is this repairable by cutting out the damaged section and splicing in a new piece with some tubing connectors and hose clamps?

 

Terrible idea … it’s a fuel line and should never be modified.

 

It’s a rubber fuel line, nothing special. There’s nothing wrong with using barbed fittings and new fuel rated tubing to make a repair.

 

Get the new part from a dealer. Likely they have it on hand and can show you a parts breakout to ensure the correct part. Good luck, great catch

 

Yeah, that's what I was thinking. Back in my poor youth, we patched shit like this all the time as we couldn't afford anything else. Seriously, I probably have everything the OP needs to patch this down in my workshop.

Having said all that, OP should evaluate the repair options and make the best decision for his vehicle.

 

The orange clip the the picture is a low pressure line. Op has issue with the other line -high pressure line.

 

Looks like 23902-0P010

If the high pressure line is rubber coated steel, then forget my idea!

Will they even return?



Best course of action is just go to the dealer or email them the photo. This part is one of those things that should be done in person. I think its a return hose that goes behind the intake, but not certain.

 

If it's a high pressure steel line under the rubber, I don't want to meet the rodents that chewed through that.

 

Gen3 is returnless system

 

I think one is feed and one is return to the port side. The diagrams are terrible for the fuel system but it makes the most sense.

I think it makes the most sense as the low side doesnt need a return but the high side pump certainly needs some where for pressure to leave.

Not stating as fact, if anyone has any real info please correct.

Looks like low pressure feed, low pressure damper return to low, and high pressure to DI.
