Barrel Valve Fuel Screen

Mike, I got mine from RBS it works great. I clean it every round simple and easy to deal with.

i have one in my fuel system. I am going to the larger screen type. if you get some trash in that, it can really hurt fuel flow fast. go mine at RBS

Mike,

We tested this and saw a 3% difference when leaking the barrel valve down.

Also while they do work great and we used it for a season, I don't like the fact that when you get (if you get) any grime in there it definetly hurts the flow.

All you can do is clean every round and filter fuel. We now run a System1 and can't fault it.

 

Relentess, Sorry to tell you this but I would suggest you clean your screen before doing a comparison because I think you will find that it is a well documented fact that the screen will NOT change the leak figure nor will it change the flow, you will see an increase in pressure on a flow bench but this is all.

Doug,

Yeah that was clean, we also checked it a few times and it did make a difference. This was all before an event so all was spotless.

You say it also ups the pressure? By how much?

 

screen

Mike, been using one for years, got it from Jeff Fowler.

Hate to tell you this but if the pressure increases by adding this then you decreased the flow, if all else stayed the same.
Cant change physics

 

We're ordering some today.
Gonna put them inbetween the -8 check valve of the port distribution block and the hose. I'm just trying to catch junk as close to the end of the line as possible.

Any comments about what I'm doing? Good, bad or ???

I'm assuming they can stick into the check valve, or are they too long for that?

 

SoDak,
I have to ask. Why do you have "junk" in your system?
Are you not cleaning and pickling the system after the race?

Junk is a stronger term than I needed to use.
We've run for years and years without filters and near zero problems.

I took a shutoff valve apart and cut the o-ring when I put it together. I tore the system apart looking for any o-ring pieces and found nothing, now I have what appears to be a slice of o-ring in a nozzle.


Mike

If the screen interferes with the check, I should be able to put it in the other end of that hose.

 

John,

You are absolutely correct! It is called Bernouli's Law. (sp?)
If the pressure increases, the velocity decreases. If the velocity increases, the pressure decreases. It is a law of physics and it will not change regardless of the circumstances.

 

SAE Fuel in line filter

I have used the SAE inline fuel filter in the #10 barrel valve inline fitting for many years. On an a-fuel car this fitting is removed to blow the engine down after every run and the filter is inspected every run. Only a few times have we ever had any trash in it. We filter the fuel when filling the tank so there is no trash going into the system but we have found rubber from a fuel line a few times. The out put of the fuel pump is always equal to the flow sheets.
Since we run a main jet and pump larger than needed if there was a 2-3% decrease can't see as it would be a deal breaker because we can always get more output than the motor can handle. Stop a nozzle up and see what that costs.
Hey Bob M. you ever think about the old man Frank Huzzar? I do every once in a while.

 

SAE filter

On three different flow benches I've had access to, you will NOT find any change with anything, including pressure.
One thing to remember is that no matter how well you filter your fuel, going in, you still have a vent system that becomes a vacuum cleaner that does a great job of sucking dirt, leaves, ect. out of the air or off the ground!
He also makes a screen for oil that can be used at the out fitting on the pan, that can keep your oil pump healthier.

Long before, flow meters on the car, these were a great help with learning that the brass liner in your old pump was killing itself, 'cause the filter would catch them.

Bob H.; me too. I saw a little of his and your history in Phil's "H"'s today at NHRA.com.
