| 1967 Firebird no gas getting to carb. How to resolve without just trying part swap? | 39Relevance | 5 years ago | Sagewyn | Submit Your Question HERE | |
| No gas to carburetor. I have a 1967 Firebird 400 ci. V-8 Pontiac engine. with a mechanical fuel pump and holley 650 double pumper carburetor. The car ran fine when last started a few years ago, but will not start now as it sits. It has been garage kept for 30 years and used very little , maybe 100 miles/year or less. The engine was rebuilt less than 10000 ago in 1990. Left unknown amount of gas in tank with fuel stabilizer and lead additive. Fresh fuel probably added 3 or 4 years ago. It consumes enough fuel when running so iot hin k the gas 4 years ago was realtively fresh since i fueled it up regularly. The tank was never left full jsut whatever happened to be in the tank when parked. Fuel pump is supposed to have a return line to tank, most new pumps do not have this so the return line is plugged. I do have a nos pump somewhere but it is ancient and was saving for a restoration. Diagnosis efforts so far. : 1) The car turned over and will run when you put gas in the carburetor but stops when that little bit of gas is used up. I disconneted fuel line from carburetor and turned over engine no gas getting pumped 2) checked gasoline level , 18 gallon tank seemed to be empty assume it leaked out or evpaorated?, Tank had small pin hole in bottom sealed with putty, weeps slightly. Losing gas has not been an issue in the past but i havent gone 2 plus years without starting it either. I added 5 gallons of gas to tank , attempted to start car would not start. added gas to carburetor. can ran until gas rin carb was consumed. Disconnected fuel line after the pump no gas getting to carb while cranking engine. Assume problem could be bad pump, or a pump that has lost prime (is this possible) ? or an obstruction in the line before the pump. What is best way to diagnose/fix? I could put on a new fuel pump but dont want to if it isnt bad. The car is in a two car attached garage and cannot be moved since a non working car ( i am fixing brakes) is currently blocking it. next steps? : 1) keep pouring gas in carb while someone else pumps gas pedal ( this shouldnt work since no gas is getting past pump). potential fire hazard. 2) or disconnect fuel line before pump see if gas there to rule out. I am little concerned with fire hazard of messing with gas running on ground in attached garage. If i push car outside and cannot start ti i will be unable to put it in the garage again. Bad idea in rainy climate since it is a convertible. 3) or Possibly apply compressed air into fuel tank with rag stuffed alongside air nozzle to slightly pressurize tank in an effort to prime pump. pour gas in carb and try to get fuel pump primed. is priming even an thing with these pumps. 4) or swap pump without diagnoisis and just hope for the best. ( pontiac pumps i think have alittle rid in engine that drives the mecahinical pump. cocnerned if i take off pump this rod will drop down and i willbe in trouble. I dont klnow if this is an issue though just inclded it for completeness. It would seem a relatively straight forward fix as it is a simple system. The car has never done this before. Im considering disconnecting fuel line before pump first then addressing obstruction if there is one if gas is present there considering pressuring tank to try to prime pump. If that doesn t work try swapping fuel pump. Is any of this ill advised? Should i just jump straight to swapping pump? I could also bypass mecahnical pump and install electric fuel pump, but i dont know if that will be too much pressure for holley carb. When the car does run my clothes and hair smell like exhaust, this makes it unpleasnat to drive, assuming carb issue ( bad power valve?) ( no exhaust leaks) and running rich, im concenred with gas diluting oil should i swap back to a quadrajet carburetor? What are your thoughts on diagnising and fixing please ? | |||||
| 91 Premium Fuel for 91' Toyota Pickup 2.4L (Extended Cab/RWD) | 36Relevance | 5 years ago | Rjaybruhh | Submit Your Question HERE | |
| Hello again everyone! I drive a 1991 Toyota Pickup (extended cab/RWD) 2.4L and it just reached 278,000 miles. I just saw the video about Scotty's "People Say I'm Full of Crap About premium Fuel" video. The video made me wonder if I really need to use 91 octane fuel to help with the pickup's performance. Ever since I have heard that premium fuel can help clean up the carbon in the engine and increase performance I have been using premium fuel for I would say the last 3 months. Does it really work, and if I continue to use premium gas forever will it have an ... | |||||

| Answer to: Can 2022 Lexus GX460 run on regular gas? | 27Relevance | 4 years ago | Chuck Tobias | Submit Your Question HERE | |
| What does your owner's manual say? Does it say "recommends" premium gas, or does it say "requires" premium gas? Most modern cars will adjust to the gas you put in them. My 1997 model is supposed to use premium gas but will run on anything you put in it, with less power if regular is used. (You can feel the difference but it won't damage anything.) In any case, to preserve your warranty follow the manufacturer's instructions. | |||||

| My 2004 Toyota Avalon 3L V6 runs best using Shell V-Power Nitro+ premium (91 octane in California). It does not knock or ping using lower octane fuel but it is definitely more responsive and accelerates stronger with the premium. If you are curious why not try a tank or two of a top tier premium gasoline and see if you notice a difference.🤔 | |||||
| Answer to: Putting regular gas instead of premium | 27Relevance | 4 years ago | AutoDIY | Submit Your Question HERE | |
| After doing a quick search, every single site I quickly read through said they strongly recommend using premium. Your driving a Mercedes I'm assuming for the luxury and performance, why wouldn't you just use the premium and enjoy? Your vehicle's combined MPG rating is 27: 15,000 miles a year divided by 27mpg equals 555 gallons of fuel. If premium is 30 cents more than regular you are looking at a difference of only $166 for 91+ vs. the 87 octane fuels. | |||||

| It's worth running premium gasoline in an engine that recommends it. But if it requires it, then ONLY use premium. We've discussed this topic many many times on here. In my opinion it's worth the extra 10-20 cents for premium if it's recommended. There is a reason they recommend/require a certain octane rating. | |||||

| You will actually get worse gas mileage running premium in a Corolla, and you really won’t get any difference in performance either. The only reason you would want to do that is gas companies sometimes put better detergents in the premium fuel. | |||||

In the 1st visit, when I brought it in for the first oil change, the dealer diagnosed the issue as “surging”. The dealer said this is a common problem with this make and model. The dealer claimed to have performed a “software update” to resolve the issue. The car then drove better for around a week or so. However the problem resumed. 2.

| On a car designed to take advantage of the higher octane you'll get a bit better gas mileage with premium fuel but not enough to make up the difference in cost. When gas is relatively cheap I use premium, but will go down to mid-grade when prices go up, and have used regular when prices were really high. In my case there's only a small difference in performance with mid-grade but it's quite noticeable when using regular. | |||||
