Anyone every tried the sack that is used in medical drips to make their own UAT? I was in hospital for my wife and i couldn't help looking at the ''rig'' they use off the bottom of a drip bag and it's doing exactly what a UAT does. I wonder if it's fuel resistant??

The nurse told me they just throw them away but didn't offer it to me[&o] Never mind, my sister is a nurse, I'll see what she can get for some testing. I'm sure someone would have tried this before.

Thanks

Hospital IV tubing is quite small, about 4mm. It wouldn't be suitable for our large engine installs. And that's not to mention if they are compatibale with fuel.

I changed over to JMP's accumulator on my Ultra B with a P200. I also added a larger header tank with JMP's monster fittings through out as well as drilled out fuel fittings to 5/32. After running my pump at 6V for 5:30 minutes I get small "burps" throught my pump as well.

Since JMP's accumulator is impossible to see through (machined aluminum) I can't see if any cavitation is happening, but I suppose cavitation is probable in any install if the appropriate conditions could exist.

At full throttle my P200 was at 5.0V and I've yet to try to burn through my tanks at 5.0V to see if I get those "burps", but Tom Cook (JMP) has tons of experience with these big engines...
