Slant dies when cruising.....
How do I check for water friend? I guess I could google that and not show my ignorance. meh......Keeping the flow of the thread for future.
Ill check the tube.
thank you all for advice. I thought it would have been the filter. Everything about it screamed clogged filter.
Actually it screams lack of fuel in general (clogged filter is just one reason it could be)
Another instance of a lack of fuel would be sucking air, like a rubber section being cracked.
Of course a weak fuel pump can do the same thing as already mentioned, but maybe the pump is getting worse as you go and now barely pumps anything at all. (you did say it wasn't this bad before)
Usually in a case like this I disconnect the fuel line from the pump and blow back into the tank.
Not only will this tell you the line is clear enough to make bubbles in the tank, but it will temporarily clear the sock in the tank a little so you can get an indication if it made a difference for a little bit.
Of course if this is the problem it will come back soon, but it gives an indication of where the problem is.
If for example it's a rubber line allowing air to be pulled into the fuel you don't really see an indication of that anywhere, because even though the line has a leak it's getting air pulled into the line so it doesn't leak a lot of fuel out of the line.
Another easy diagnostic if it hasn't been mentioned yet is to connect a fuel hose from your pump (tank side) into a gas can and see if the problem persists.
This will give you an indication of whether the problem is from the pump back, or from the pump forward.
I have also seen pickup tubes inside the tank cracked or rusted holes in them allowing air to be sucked in instead of fuel being pumped. (again, you did say it seems to be getting worse and worse)
Heck I have run motors with a 1 gallon gas can tied to the antenna just to get the car home.
This doesn't use any of the existing fuel supply system at all except the carb.
Gravity feeds the carb, so none of the tank, fuel line or fuel pump is involved at all.
This can also be done to run the car and let the fuel pump empty into a bucket to check if there was a lot of air in the fuel or a low fuel volume.
Blow back into the tank (it takes a bit to clear the line of fuel and start making bubbles in the tank)
Do you hear bubbles?
If yes, suspect air being sucked in when the pump is in use, or the pump itself being too weak.
If no, try again as like I said you need to clear the line of fuel first and it takes a little bit.
Still no bubbles?
Look for any slightly wet spots in any rubber lines, or a cracked or rusted through pickup tube in the tank.
Can't blow bubbles in the tank no matter how hard you try?
Disconnect the line at the tank and fuel pump and see if air goes through that.
Eliminate the blockage section by section instead of trying to figure it out with the whole system involved.
