Sample tube info from Noobz:

Thread 'C & L Maf Sample Tubes'

Jul 12, 2017
Can anyone tell me what the inside diameter is for the various color sample tubes and what injector size they are meant to be used as? Thanks I need a 24# tube.

I may have asked this already but have you cleaned the MAF sensing element?

Noobz beat me to it. I was Making good and sure I remembered what a C&L looked like. I had a BBK cold air and if you clamp the blue boots down on a 55mm housing it’s ugly looking as the stock MAF housing is about 2-1/2” OD vs the boots being around 3” ID. Those boots are tight which leads you to a larger MAF.

Yes it’s a little ugly but Damm it runs nice when it runs good .

Remove the sample tube and clean it. Clean the MAF sensor while you're in there.

So I use brake parts cleaner on a q-tip and very gently clean the heated element. After that I hose it down with MAF cleaner and let dry. Last time I cleaned one I could literally see a light build up of dirt on the element. This was on the 80mm OEM MAF off of a 2000 GT from a salvage yard that is on my Coupe so I have no idea of its past history but needless to say it would have been a problem.

What is the fuel pressure like? I am so suspect of any distributor but an OEM one when stuff like this comes up but it seems to be getting fire and its more like its over fueled.

I think I have the fuel pressure at 35 with the vacuum line on I think. This one I just bought. They work pretty well. Before this one I was running another one but it’s still found the same thing.

You want to remove the vacuum line and cap it. Adjust the FP to 39 psig and then reattach the vaccum. My guess is you are a llittle high on pressure as typically at idle you will see about 30 psig or so. I am not saying this is the problem but its not helping. Also, check the vacuum line for gas in it. If it does have gas in it then the FPR is fubar.

Of course . Both good things to check. I will adjust the fuel pressure

I’ll tell you what I’m gonna do. I’m returning the distributor for another one it’s under warranty & set timming again & I’ll swap the coil I think it’s under warranty as well. Start over again before I buy an ecu. It’s weird cuz while I was adjusting the fuel pressure i thought let me check the timming & it was over advanced like 20 degrees instead of the 14 I run it with. I swear I set timming to 14 & I thought I fixed the problem it’s ran good for a minute or 2 then was back to running ragged . Before I swap the distbutor (take few days already let th know ) I’ll keep tinkering with the fuel pressure now that timming is on 14. I have no idea how it moved but it did unless I didn’t tighten the bolt.?
