Changing a gas tank

Evo Dragon said:
Someone own car with fuel injections. He installed wrong grade fuel rubber lines while driving and then, leak gas. It got fire on engine. It should use psi of up to 200 fuel injection high-pressure hoses. And not standard fuel hose use for Carburetors only.

Happened to a young mechanic who installed unlabeled fuel hose in a 2000ish Isuzu Trooper at my ex work, one month later customer complained strong gas smell under hood. I went to check the fuel leaks, found 2 long hoses under the tranny tunnel, noticed hose has no labeled. I asked a mechanic where did you get hose, he showed me a bulk that label says fuel injection, I found out someone place PCV hose in a box. Damn. We replaced new F I hose. No comeback... I've notice many newbie mechanics didn't read labeled hoses before installation.

Fuel rails on my 97 dodge Ram 1500 used standard fuel line to bridge the rails, the working pressure was 44psi so depending on the vehicle.

I saw a PCV hose installed at the tank but the line is return hose nothing wrong with PCV hose because the return hose is very low pressure where the excessive fuel dump out from fuel pressure regulator to the tank.

Return lines can be pretty much anything due to lack of pressure, seen pcv lines repaired or replaced with standard rubber lines. I have seen some fuel pumps use regular rubber lines as well.

7.3, 6.0, 6.4 are gas model? Your funny! No, they all are turboDiesel Engine and they don't have emission control like Gas does. 6.7 is newest one with more emission control and thats 2011. California is only state that requires add on Emission control as early as 97.

Diesel vehicles with turbochargers or non turbo, still have emission control system. They still use PCV, air filter housings, fuel caps and EGR valves if equipped. PCV design to prevent HC fume up to atmosphere, PCV system is include oil filler caps too. Same as gasoline powered vehicles. Understand clear?
 
diehardbiker said:
Yeah, he forgot about Diesel, and Natural gas... Oh wait! there is no emission control on Natural gas eh?

Or how about 1957 Chevy that one of ADers driving with emission control? They are gas, don't forget that!

I still inspect/smog NGV(Natural Gas Vehicle). They doesn't have EVAP systems include gas cap. If you happen smell strong propane fume from under the vehicle or engine compartment, fail it for gas leak or fume. I can't fix it, have a customer to take it to the NGV repair shop or dealership. I never diagnose NGV before.....

well we changed the fuel filter, and the injectors seem to be working...they spray stuff out...at least until suddenly it just stops and the van dies. Since neither me mate nor myself are mechanically inclined thats about the extent of my knowledge. Wouldn't surprise me if someone was trying to make a "quick" buck off us, but it could be that the tank is just filthy. It is an old van.:hmm:

I read this post few times, the sentence says the injectors seem to be working... They spray stuff out... At least until suddenly it just stops and the van dies. My question is who spray stuff out? Injector? Mechanic ? Sound like Mechanic spray it with carburetor cleaner into the throttle body.. I'm not sure. Can you explain to me more clear. Please.
 
Bad gas because of the gas tank? That sounds more like the fuel pump.

I had a bad gas mileage in my car a couple years ago. It was a bit noticeable for a few months, but it got pretty bad. I planned on getting it checked.

When I went to get my oil changed, they informed me that I was leaking gasoline. That's when it made sense why my gas mileage was very low. So, I had it checked and it turns out that it was the fuel pump. I had the fuel pump replaced... and my car's all better again! :)

External fuel pumps are found in early European cars. Easy to detect gas leaking by smell strong gas vapor under hood (leaky fuel lines) or under the body (loosed or cracked fuel hoses at the external fuel pumps).
 
I suspect the bad gas in tank what OP mentioned is this van has been sitting for a long time, gas became stink. OR I also suspect this van got diesel in a gasoline tank? Just guess.

My old toyota had a mechanical fuel pump attached to the motors head. It wasn't uncommon for the diaphragm to start leaking and dump gas into your oil. I used to smell my dip stick for gas every time i checked my oil.

I told a guy he was pumping gas into his diesel once. Was his boss's truck and he didn't know the difference. Had to have it towed. The diesel pump nosle is to big to fit into a gas car though but i suppose it could be someone put diesel in a gas can.

Yes, I've seen leaky fuel pump few times. One time I fought a 79 or 80 Toyota Pick up truck in 20 years ago for high CO emitting, check air filter, choke and float level all ok but I notice wet fuel pump on the side of the cyl head, not drip. I ignore it and concentric on the CO level somehow I decide to pull a hose from EVAP canister, plug it, the CO drop little,then pull PCV valve along with hose from valve cover, saw the CO level drop to normal level at engine idling and 2500 RPM. I double check the carburetor , seem ok. I was not able to figure out why then look up the emission book, dig the page, found the information of excessive CO, realized the reputed diaphragm in fuel pump, caused fuel enter the crankcase. I went back to pull a fuel pump out of cyl head, found leaks inside the body. New fuel pump fixed it. CO level looks normal.
 
Only very few Diesel pump nozzle would barely fit in the gas cars, it is newer one and designed for Diesel cars only.

Mind you, I was so pissed off at gas station in Mass pike for refusing let me use the truck Diesel fuel lane, asked me to move my vehicle to other pump where it will fit in my vehicle refill point because that pump got bigger nozzle and won't fit in mine fuel point hole. How dare she telling me what to do? I know my truck and I KNOW it will fit in just fine. She don't believe, and I had to drag her to the pump and show how idiot she was. She gulped, never insult Deaf Diesel truck owners! Happened TWICE on Mass pike one on each side different attendant, and even worse same week!

I prefer 18 wheelers fuel pump lane, know why? FASTER refilling! These 18 wheelers fuel lanes have higher output than regular car lane, because of usual size of tank, cars usually have 10-20 gallon, while truck can have as much as 300 gallons.

But its possible gas can used, I highly doubt it why extra work?

It was a Chevy Cobalt. I originally thought it was my fault. The year before, I ran over a huge chunk of ice that popped out of the road during an ice storm. Thought that might have caused the fuel pump tubing to crack... leading to the crack to get bigger through the hot/cold climate. A year after I had it replaced, there was a recall due to a faulty fuel pump. Luckily, they reimbursed me for what I paid to have it replaced. Good thing I saved the receipt! :deal:

From my old job. My old tech told me that someone filled up the Chrysler 300 with the diesel and I said how hell nozzle can fit in the gasoline's hole?! He said NO CLUE! Maybe used paper roll to fit it.
 
Ok, guess next time I go to pump station and take picture of two nozzles one for diesel and one for gas, almost same size! At first I don't believe my friend's claim about 3 years ago, so I checked and I was gulped, he was right. Why not go to VW dealer and look for one thats TDI, check their filler cap, whats size inside. You will be shocked. I find this STUPIDIEST idea from EPA. The intention was to prevent from high speed pump into 10 gallon tank that VW TDI has.

Check this forum, see first post of that newly VW TDI owner in shock, can't get regular Diesel nozzle fit into his TDI fuel filler. Have to find gas station that said "Auto Diesel" instead of just Diesel.

And check this accessory that comes in with VW TDI vehicle as back up if can't find auto Diesel pump

wait I'm confused. are you saying Highlander is right?

I have no idea about the size of diesel gas pump. I've never touched one in my entire life :lol:
