The saga continues - Sputtering, loss of power when accelerating
Driving along this morning and everything was fine. All of a sudden it starts sputtering when I accelerate and I'm not getting enough power.
It's had all new plugs, points, tuning etc..... However, I've put an inline fuel filter before the carb and that has some crap in it. Not a huge amount (I once owned a straight 6 Fairmont that would run like a champ right up until the filter was chock full), so I wouldn't have thought that would be the cause? Naturally this has happened the day I decide to take it to work. So now I'm here all day being paranoid that I'm going to cause damage trying to nurse it home. Or that it's not going to make it. Oh, it's a 61 305D if that's relevant at all. And yes, it has petrol (although at the moment I am having to use a broom handle to determine that). |

Re: The saga continues - Sputtering, loss of power when accelerating
Is it re-useable? I guess what I'm wondering is if I take it off and give it a fling out (hopefully removing the crap that's in it, if that's the problem) will I be able to just pop it back in?
This is just so I can get it home of course. I'd be getting a replacement first chance I get. Also, when you say the gas runs down you're arm, does that mean it's going to just keep spewing out of the tank until I put it back in? Or is it just going to be whatever amount of gas that's currently sitting in the filter? Fingers crossed it's something this simple. I'd be pretty devastated if it was something catastrophic. |

Re: The saga continues - Sputtering, loss of power when accelerating
Just went through this. Ended up being that the sending unit did not have the screen on it allowing a ton of crap through the line and into the primary filter. And with an electric pump you know something is wrong Right away. New sending unit, 2 new filters, blew out the lines and for the 1st time I am actually seeing 10 psi cold.

I'm really hoping it's something basic..... There is some crap in the pre-carb filter, and pretty much the only mod-con that the truck has (other than seatbelts) is an electric fuel pump. I've already got a new sending unit on order (as much as I don't mind checking the level with a stick, it's not something I want to keep doing). So, fingers crossed? Is there a chance it could be something major? If so, what other symptoms should I be looking for? |

Re: The saga continues - Sputtering, loss of power when accelerating
I had an old Fairmont before with a badly rusted fuel tank. Consequently, I had to carry a tank of compressed air in the back seat so that when the sock in the tank filled with rust I could pull the line off the pump and blow air back through the fuel system (which blew the rust off the sock) and then suck petrol back up the line, reattach it to the fuel pump and keep going.
For the short term (IE getting me home today) could I do something similar as a test? I don't have a tank of compressed air, but I'm thinking if I blow into the fuel line really hard I might be able to lung it? Except I'm assuming since this is an electric fuel pump I won't have to suck petrol back up the line afterwards? Also, there's a shutoff valve on the petrol tank. Presumably if I close it then that should keep the tank from emptying when I pull a line off? I know some of these are going to be 'duh' questions, I'm just well aware of my own limitations when it comes to experience and whatnot, so I'd rather ask a dumb question than assume that I know what I'm talking about and make a dumb mistake. |

Unless you have all the tools you need, I'd limp home and wait until the weekend to do any work.

Re: The saga continues - Sputtering, loss of power when accelerating
My 64 suburban did not have a filter between the tank and the fuel pump, so all the crap filled up the fuel pump. took the pump a part cleaned it out. put a filter on the tank side of the pump. In the end, I took off the fuel tank, pressure washed the inside,used muratic acid to clean, lined it with red coat. Tanks that are real bad throw a chunk of chain in it and shake it. The best redneck way is to fill with some gravel, strap it to a tractor tire, and go for a drive.
