Racetronix key on position spikes to 62 then drops rapidly. Hard to restart hot car. Anyone with the Racetronix kit chime in and let me know if yours does the same?
Will see 62 psi on key on and then it drops down pretty quickly to 25. Will continue to bleed down to 10psi or so in 5-10 mins.
Removed injectors from intake and did key on with paper towels under them. Unplugged hardness for injectors. Did not notice any fuel leaking from injectors.
Have been having issues with restarting car after it has been warmed up. Cold start does not seem to be an issue. Car is cranking but not firing up. Starter is fine, HP tuners is seeing 150ish RPM when cranking.
Sometimes I am able to get it to start after cranking on/off like 5 times. Other times the car has to sit a bit before starting.

Good luck with Racetronix on support.
You can double check to make sure that the flex tube in the bucket assembly (The clear one from racetronix) is secure. Mine had a massive "leak" when it did this. I was able to get new tubes and re-crimped new one on extra tight and it at least holds to around 50 psi for starting.
I tested above by taking fuel assembly out of tank and having buddy turn key on and seeing if it "sprayed" out around those joints..... i will admit that i made a trap door so this is obviously easier to do if you don't have to take tank down lots.

I did purchase a new fuel regulator. Will be replacing it when I pull the pump. Do you know what size the clamps are that come with the pump? Thinking I may not have clamped it good enough and may replace it.

I did this same swap over the weekend with the Hot Wire kit. and having the exact same issues as you. 62 psi then drops.
Also takes me 2 times turning key on to get to the 62psi....going to possibly change out the FPR tonight.

Let me know how it goes.
im in the same situation as you. Installed pump and hot wire kit a week ago. Going to try the fpr regulator on Wednesday and double check connections on pump.
