All Volkswagens especially those with flat fours (without updated/modern fuel lines; and old neglected ac wiring)

Pretty sure the fuel lines were replaced, but not sure if it was replaced with metal mesh or rubber hoses. Will be checking tomorrow!! |
don't forget lines/connections between fuel rail and injectors |

any recommendations for a particular type of check valve on the return fuel line?
is it true that fuel in line won't drip because the pump has stopped? |
It needs to be a spring loaded check valve so that it doesn't pressure in the reverse direction to close it. |

Not necessarily... Here's a pic of a van that burned up because of an electrical fire in the driver's rear A/C wiring.

Truth! Fuel lines are important, but the nest of wiring behind the left D pillar is a fire waiting to happen. Especially during hot summers when you're blasting the A/C. I'd check them for melted or deformed relay/fuse holder. _________________ 1986 Syncro Westy

When I see these photos it makes me want to write in a fuel and power cut off. has anyone down this. Seems like it would be simple enough to wire in a switch that would cut fuel and power.
I guess the other issue is having a correct sized fire extigusher _________________ 64 bug

I've seen many vans with melted AC wiring in the back corner
and melted Alternator to blackbox to starter harnesses.. which runs right over the 2 fuel lines.. _________________

If the material can handle gasohol then it would be okay.
I found a 1/4" or 3/8" NPT brass spring loaded ball check valve and added fittings of the appropriate size to get it to work. Mine is mounted close to the tank and I have steel tubing between the engine bay and the valve. The transition between the rubber hose coming off of the FPR and the steel tubing is made as high as I could get it to further lessen any chance of gravity feed. I have steel tubing on both the supply and return side.
This isn't the one I have but is quite similar:

I hate seeing burned vans. My sympathies to the owner. A Syncro with the plastic fuel cell right above the back of the engine is a risky vehicle. I can only imagine trying to contain that fire once the fuel cell wall was compromised. The crew at the gas station were brave or ignorant. Getting burned is a horrible thing. Damaging your lungs fighting a fire is just as bad if not worse. I'm grateful nobody was injured. As Vanagon owners, it is your responsibility to make your vehicle safe. It protects you, people around you, the environment (could make one hell of forrest fire), and lastly your investment. Maintain your fuel systems, and purchase quality clamps that match your fuel lines! I have seen many a clamp improperly sized making it an oval instead of round. I have also seen cheap clamps overtightened cutting into, and compromising the hose. If you do not have experience with fuel lines or clamping rubber please feel free to reach out for some mentoring. I will help as will many on this forum. If you are doubtful, it is truly best to have somebody with experience show you, or check your work. Tightening clamps is a feel as well as visual task. I've been a professional tech and had a learning curve in my youth. Fortunately it was on coolant lines and caused no damage. Just a little coolant on the garage floor and the dog didn't lick it up. Lets Just have the event Burning Van and no more actual burning vans! |

I see membershit to to bid on a vehicle on that site is $200/Year. Is there any other way to bid on vehicles such as this one?
Has anyone ever seen a Subaru powered van Car-B-Q? I have not. Plenty of Bostigs, but no Subys.???

Glad no one was hurt. |
As far as a visual inspection goes, keep in mind that the way the fuel line looks on the outside could just fool you into thinking all is well, while the line could be cracked on the inside.
Also there have been recent reports of folks having cracked/compromised fuel lines within a year or 2 of new replacement. Maybe that was a combination of poor quality hose combined with regional ( e85 ) combination, I don't remember.
But I saw the pics posted on here and it wasn't friendly looking....or at least that is what my memory is saying to me. If I'm worng about this then I'm sorry for spreading unnecessary widespread panic.
Probably best for anyone who isn't very knowledgeable and sure of their own situation to simply replace fuel lines every year or two around the engine bay, injectors, with an elimination of the plastic connector at the firewall too of course. _________________ One of these days I'm gonna settle down,

Lets say that a fire gets started and you shut off the engine. If it burns long enough to compromise the line from the pump, well that line is pressurized and it's going to spray out that fuel. Then if the fire involves the electrical system I *think* the pump could be activated and feed fuel from the tank. I'm not an electrical wizard though, so I'd like to believe that wouldn't happen. _________________ One of these days I'm gonna settle down,

2 years is on modern rubber lines with ethanol fuel is like 30 years with the original lines. The fuel we use today absolutely destroys the rubber hoses.

It is expensive, but what about replacing the entire system with Viton? Impervious to everything and its good to 600* F I think. _________________

the modern hoses work just fine on E-85
if you want to use the same feedstock as fuelie dragsters, you need to spend the money they do |

About 20 years ago, a couple in a large RV towing a vehicle drove across Idaho on the 90. The towed vehicle had the parking brake on or something and various motorists later reported honking and pointing rearward, but the driver did not acknowledge and pull over. It was smoking. Eventually, things began to overheat and shed burning rubber and sparks and still the guy drove on - oblivious to the now dozens of honking drivers. The police were called. Finally the towed car caught fire, or they stopped for gas or something - can't recall how they finally discovered it. But they started dozens of brush fires along the freeway and Idaho billed their insurance company in the million dollar range for the damage and the emergency responders spread out over a multi county area.
It sounds like the folks in this tan Westy will not have enormous liability, as they did not act negligently, etc. But it has been in the news this year with a lot of Western communities that everybody is on clear notice that no fireworks are allowed, and no campfires or burning of ANY kind until further notice. So with things on edge, dryness and heat at record levels, someone starting a fire under this condition will surely be prosecuted. Everyone is tense. I saw the county's mass disaster response vehicles staged out on a couple side roads yesterday on my jog. I have never seen them out before.
Everyone have a safe 4th of July. And change those fuel lines!!!

What is it with you and Bostig/Zetecs? Show me any Bostigs that have burned.
The majority of van fires have been stock VW engines.
You live in California and the Bostig conversion is not legal there, are you just jealous? Is that why you are always bad mouthing Bostig?
I have had a Bostig conversion since 2009, it has given me thousands of carefree miles. Both the fuel and engine electrical systems are uprated with a Bostig conversion.
Of course with any conversion the installation needs to be done properly and here the Bostig shines by providing a very clear and well made layout.
Give it a rest. You are just spewing unfounded garbage. _________________ Currently:

Trailer cause fires are all to common. It is hard to realize that something odd is going on back under the trailer until sparks are flying. On I-84 to the east of us they get many trailer caused fires each year along the highway. |

1) I have heard the OPPOSITE. That the Vanagon fuel line problem is a 2WD problem and NOT a Syncro problem. This is the first Syncro I've seen burned, and didn't see anything identifying the cause. I have not evaluated every vanagon fire. My Syncro has never leaked gas and I'm happy for that.
2) I have heard that there will generally be a "warning" that your fuel vent hoses are leaking. In the form of gasoline fumes, or raw gas dripping from the fuel tank area when the tank is near full. Or driving on rough roads, or parked on a slope. In ideal conditions it could warn you before it gets ignited. I have heard of folks who were warned by the smell, or dripping, and did not have a fire. I have heard of folks who changed their fuel vent lines and it leaked again a few years later.
3) There is a plastic bulkhead fitting in the engine compartment on the forward bulkhead that is pretty dangerous (if old and brittle) because it's in the hi-pressure side. Heres a pic from GoWesty Fuel line kit.
Can't really put my finger on it but it kinda looks like trouble doesn't it? I guess it all depends how you look at it.
4) And the engine compartment hoses too. _________________
