Looking for no bs, tested, quality vacuum caps..

[SquareRoot]

If were turning this into rocket science I have an idea? Identify the ports you're actually going to use. Then take a pair of vice grips and remove the unused port nipples. Two suggestions to fill the hole depending on your level of OCD and anal retentiveness:

a. Tap the hole and install set screw.
b. Dab of JB Weld.

Have a beer, pat yourself on the back and worry about bigger issues.

They’re pricey, and they do fail eventually, but probably not for 10 years or so. If you only have a few ports to cap off it might be worth getting just enough to cover what you need

Try going to a parts store...check the Dorman bins...this way you can put your hands on them .I didn't care for the vinyl caps either...

I just use a short piece of hose with a stainless Allen round head bolt in it.

Nothing has worked better for me over the last 40 years then a very short piece of fuel hose plugged with a screw or bolt.

Not trying for show car status. Trying to have it last without looking like ****! You just have a certain image in your head about what it should look like.

Thanks for the ideas guys! A few good options here.

The ones i had were Dorman I believe, or close to it, they feel nice and pliable new, but after a couple months they either split completely or start cracking.

Try these?

I can give em a try at least. Thank you!

Dorman makes a lot of crappy rubber parts that go to pieces in a hurry, and they refuse to replace them. But why would you want to replace crap with more of the same crap?

High Temp Silicone Rubber Vacuum Caps

Kinda pricey 80pc kit but I bet they can be had in lesser quatities.

*added to cart*

Ethanol in the fuel is probably not helping either.

Put ball bearing in cap then install. No fumes to rubber parts.

Y'all are genius. I've never thought of ball bearings.

@ PrairieDrifter,

Moroso makes high temp caps for carbs and anything else like that. I've had good luck with them. You get a pretty big bag of them, all different sizes, and colors.

@PrairieDrifter,

That's like me, I don't want to have to think about checking anything like that unless a problem occurs, then I'll look but I would in the process of checking anyway. But I don't want to always be thinking, "Oh, let me check those caps!" No! I want to drive my truck, stop and get gas, and drive my truck. If I open the hood it's to check the oil or trans fluid and only if I think about it I will grab a hose or something. But I'm not going to take the time to take the air cleaner off for anything unless I think I have a problem under there. Other than that I want to be driving my truck.
