Does anyone know the correct reservoir cap adapter size to use for pressure bleeding the FFR supplied reservoir in their complete kit?
I measure around 42-43mm inside diameter for the FFR supplied cap but would appreciate anyone that has information on actual part or built one that sealed well without leaking.

I believe it is 52MM. I purchased this kit and one of the supplied caps fits perfectly. MR CARTOOL 3L Brake Bleed Kit... https://www.amazon.com/dp/B0D9NXLK8Q?ref=ppx_pop_mob_ap_share

This was for the FFR supplied reservoir and not another aftermarket vendor?

I used this kit with the FFR-supplied reservoir.

It's a 45mm.
I have the 45mm Motive kit (I JUST looked on the label to confirm

One of the best 28$ you're gonna spend on this project.

I 3d printed my own. Can't remember the size, but it works great. I wish I knew about pressure bleeding when I was young.

For those of you using a pressure bleeder - are you also bench bleeding the M/Cs first? Just curious.
I am finding that the bench bleeding is more annoying than usual with the remote reservoir configuration.

No bench bleeding needed as far as I've seen with the HF unit.

Hi Jen. I ordered one from Amazon and it had a cap that fit the reservoirs perfectly. Here's the link.

I bled my fronts before installing the rear just to be sure that my flares were performing as I hoped. Everything worked out great and the bleeder worked perfectly.

I bench bled my master cylinder in the car. Used a mason jar and some clear tubing.
