You should vent it to your muffler! Get some bad ass flames going!

uuuuuuuuum, no!

I hope it was the source of your fuel problem. Instead of an open vent I used a 2-way check valve from pegasus racing that keeps the tank sealed until a certain amount of pressure. This way the E85 will last longer and not absorb the water from the atmosphere.

I'm sorry Billy but I gotta laugh at the having no vent thing, LOL

Do you still have a roll over valve also?

Yea, yea, yea, its my first cell and that's how Dads built it to be used with a stock style fuel pump. Haha

I thought the silver thing on the red cap was a vent?

It is a in only vent. It is VERY small though. Now I have -10 venting.

I've seen clogged vents on motorcycle cause the tank to cave in.

No roll-over valve on mine. I honestly don't see the need for one if you put the end of the vent tube low enough and also the check valve I used should somewhat serve a similar purpose.

Interesting!

If this vent fixes my issue I will look into it.

 

[dysan]

Well, the issue is that they only offer the one I am using in a -6 size so if you want to use -10 then it won't work.

I do like the sound of the 2way check valve. It looks like the small vent on the cap just wasn't enough to handle all 3 pumps and created a vacuum in the cell. Good luck nest Sat......

I have also seen motorcycle tanks collapse

Any updates?

Went back to the track yesterday and the FP is still dropping! Not real sure what to do at this point. I'm going to call Fore tomorrow and pick there mind about my regulator.

 

[travelers]

Dam that's some bad luck, I hope they have an idea....

Just a thought, I would disconnect your feed line up front and connect another line to a bucket and see what kind of flow you have before and after the regulator

I don't know if that would work correctly because aren't the regulators boost referenced somehow?

depends on the regulator I think but my Fore f4i certainly is

 

[05stroker]

My Fore regulator is boost referenced. Fuel pressure is fine until about 6k and then it drops like there is not enough pump.

I've probably missed it but how are you monitoring FP?
