I've bought some replacement parts with the grease fittings on them, about 10 years ago. Definitely would not expect it on a new car, though. I believe that, at least some, commercial trucks still use them (because these types of parts are more durable/stronger). So maybe the Silverado wants to be perceived as a real truck? Or else, they just use some of the same parts with the big ones Is there anything about these said in the owner's manual? Like get a grease gun and lubricate them every time it rains? 🥲

Let us know what you find out 🫠

Sounds like some serious project plans. I assume that you've already considered just getting another car that already has all the desired properties and does not need so much work? 🙃 Between work and family, having a nice car you can readily enjoy is priceless.

I would not expect a slight pressure loss causing any noticeable difference for the carb. I doubt that the engine will use that much gas that the bowl gets empty and the pump is struggling to fill it due to, essentially, an equivalent of a slightly longer line. Just try putting your soft hose back on, without changing anything else, and see how it works 🙂

I am not really into hydrodynamics, much, but here is the most general rule regarding bends and flow restriction I was able to find in a smart article: Designers usually apply the general rule that a 90◦ elbow bend has a pressure drop equivalent of 30 to 50 pipe diameter lengths of straight pipe (page 40).

So, if you use your new fancy metal line + electric pump there is no problem? Have you checked your mechanical pump output and pressure to make sure it is within specs? I am only using a mechanical pump, by the way, and did not notice any issues with the fuel delivery 😏

Well, the carb usually has a reserve of fuel in the bowl, which is kept-up by the pump. The pump is generally pumping more fuel than you need, that's why we have the shuf-off float and the needle in there. I would not suspect that whatever you did to your lines is causing the carb to starve on fuel. Thus, I would look for another explanation of the observed performance problem. Maybe even not a carb-related explanation. If everything else fails, have you tried putting your rubber line back on to see if it changes anything?

I doubt that a 90-degree fitting will create a restriction of any kind, unless you did something very special. And I assure you - you are probably not that special 😁 Can you please remind us what seems to the the problem, though? Is the fuel not getting into the carb? How do you know? Did you remove the top and confirm that the bowl is not filling-up while the pump is working? How about if you manually push/blow some gas/air into your custom line from the pump's side, is it going through?

Looks very interesting, and appears to be mostly original. It's a shame they are selling a family car. Probably an older re-paint. https://www.facebook.com/marketplace/item/669161372209475

Wrong forum... But that does look nice and cheap, which is a very unusual combination, these days 😀

The above is a modern aftermarket version. The OEM-style one should look more like this: (this image is stolen from, the internet). This thermostat has two valves moving together as the bellows expand - one to close the bypass, and the other one to open the radiator loop. I know these very well, because I had a wrong one installed in my 201 by the PO. The car would warm-up forever, and then overheat after reaching the operating temp

Are you sure that this is a correct thermostat for the Flathead 6? The top part will open-up to close the bypass. However, I am not seeing the side opening for the radiator flow🤨 Otherwise, yes, bellows are at the bottom. EDIT: the top part opens the radiator flow, while the side opening operate the bypass.

Saw on FB: https://www.facebook.com/marketplace/item/29309839975296310 Shows obvious signs of poor repairs, but looks like an interesting project 🤔

I was under impression that the resistor is bad for the spark. The only reason those are used, everywhere now days, is to keep the RFI in check 🤨

Rich, You've already posted this in 2023: Getting a bit older? 😂
