Bucketless sucks - I keep running out of gas at 3/4 of a tank.

I have the Fuel-It stage2+ bucketless LPFP. I keep running out of fuel when cornering hard even at 3/4 of a tank.... Does anyone here run a hydramat and did it fix your problem when cornering hard ? I really don't feel like spending 170$ on one and taking a chance to still have fuel starvation issues.
Otherwise, do you think Fuel-It would be willing to sell me whatever is necessary ( I think the T and the hose to the venturi ) to stick the pump in bucket ?

I made a bucketless myself with a hydrant. Absolutely brilliant. Never had a problem in years. Even down to empty on the fuel gauge running on fumes.

I was under impression hydra mat is easily clogged and not intended for daily use ? I would love to use one if that isn't the case cause I deeply regret being bucketless

I've been running a bucketless setup with a hydromat for a couple years now no issues. Ran it down to 0 miles a couple times too.

I don't need bucketless now that I will not be running e85 I originally was building for e85. I jst have been dealing with so many other things between my pd clutches and trans rebuild and turbo install ,now I have a good prob in that these turbos are moving alot if air and my rail pressure may be issue at 24 lbs. I will say my spool is close to stock my lag is better than stock and I blew the doors off of a couple China turbos and a pure hi flow and n55 pure setups. That was all on 22lb map but it was tuned for slightly higher than 93 octane. I was trying to run at mpact but my friend blew his engine roll racing right next to the track and another had his oil cooler line break from highway debris, then my rail pressure when I tried running higher boost maps so it just seemed like sonething was saying we all got a big unprepared and should call it quits lmao.

Hi. Get a different pump.
I ran the bucketless for a while, and would have the same issue- fuel starvation as early as 3/4 tank. I bought the T hydromat that was almost the same price as the pump. It improved it to only getting fuel starvation at 1/2 tank.

I now run a bucketed pump. I will STILL get fuel starvation at 1/4 tank on long fast right handers. A surge tank is the only fix for that. But I just make sure to never start a session below 1/2 tank.

The radium kit is probably the only complete solution to this issue, but it's quite costly. I went with a bucketed stage 3 kit that's way overkill atm, but will be worth not going back to re-do the assembly later. Hydramat is a bandaid, better to just do things right once.

There is a note on the bottom of the page that states that:
NOTE: These kits include a basic filter assembly. When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump. In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns. Again for those applications we'd recommend one of our standard pump applications.

How does "vadersolutions" solve the issue? Omar was just posting the other day that there is no fuel starvation with his bucket-less kit...

And fuel-it claims the issues kick in at 1/2 tank, while OP had problems at 3/4. Vendors exaggerate or add qualifications in fine print. Nothing new here. For the price VS is charging, they're not including a hydramat.
