    Mechanical fuel pump recommendations

    I put a Carter M6903 on my ‘69 383 4bbl last year. It’s perfect for my application…

    Removing Fuel Pump on GTX

    With the pump removed, plug out and push rod in...insert a reference object into the plug hole (i.e. pencil, stick, finger lol) and bump the engine until the push rod is in its inner most spot of the cam revolution. Your pencil will slide in an out as the push rod rides the cam lobe. edit...

    Removing Fuel Pump on GTX

    My small block does not have a plug, nor a push rod for the fuel pump. This is likely the case for that 318 of yours as well.

    Removing Fuel Pump on GTX

    I remove the plug holding in the push rod. I do like to check the length as several folks around here have recommended to do that while the pump is out already. I'm told it's recommended because of some poorly made push rods that are manufactured these days, and the metal composition can be...

    Removing Fuel Pump on GTX

    A little grease on the inner end of the fuel pump push rod will help hold it in place upon reinstalling. Rotating the engine so the push rod is on it's inner most stroke will save some grief upon install as well. Check for proper push rod length while you have it out already. Not sure on a 440...

    Help with a sending unit please

    Ed, it sounded like you had a meter question too? Forgive me if I misunderstood you here. In multimeters such as yours and the Fluke @T2R9 is showing…if the selector only has (1) position for resistance it is typically “auto-ranging”. Saves the user from having to know the range of value of...

    69 383 roadrunner fuel problem's

    Any record of when the carb was rebuilt last? It may be time to look at that if so. If the previous owner let it sit for any length of time, especially with ethanol gas in it, it may have had some adverse effects on that carb.

    What kind of air filter is that? (472 Hemi 2x4)

    Agree with @PurpleBeeper. You can search for a filter using K&N's filter dimension search tool. Here: Search By Dimensions

    New fuel tank and pad

    You know what they say Dave; “The greatest form of flattery is mimickry”. Take it as a compliment.:poke: I personally can handle (2) Plum Crazy 70’s around here like that. In fact, I prefer more lol.

    Inline fuel pump switch

    Is that inline pump the main fuel pump? Or do you have a mechanical pump as well? A lot of guys install the inline fuel pump to prime the carb bowl after the car sits for a length of time. In that case you may want reconsider making that pump automatic with keyed ignition. That’s a beautiful...

    Can worn valves mimic rich idle mix?

    Hahaha, love it...

    Can worn valves mimic rich idle mix?

    Well, I'm much more confident that what I'm seeing is normal for the vehicles' age and setup, but... My original question still stands. Could a valve or valves be worn so bad they could mimic a rich carb condition as in the "sooty exhaust" example here? Hypothetically speaking, could there be...

    Can worn valves mimic rich idle mix?

    Sounds like I'm in good company lol. I do try to let them run long enough to burn the moisture out of them but sometimes it ain't in the cards for the circumstances.

    Can worn valves mimic rich idle mix?

    After either car warms up, the black stuff at idle goes away. Upon hard acceleration one car will blow black smoke, but not while cruising. Haven't put the other car through the paces just yet. And likely won't. Not into hot rodding that one.

    Can worn valves mimic rich idle mix?

    Definitely going to put this info to good use. And whole lot of other good tips on there too I see. Thanks!

    Can worn valves mimic rich idle mix?

    Ok, that makes sense. For a minute I was looking at things upside down in my head. Is there a certain amount or percentage of loss that is acceptable when putting a vacuum on it?
