Gary will that vst hold enough fuel? I just cleaned and flowed the injectors in my 300x and at 5ms at 5000 rpms they are cranking out some fuel.

My fuel set up is a little different, the VST is only used as a reserve tank for return fuel from the fuel rail. Fuel from the Holley pusher to the VST, VST supplies fuel from a bottom drain to the external EFI pump, EFI pump pressurizes the fuel rail, return fuel from the fuel rail goes back to the VST. It's a big loop which will never run out of fuel. I agree 6 injectors at 5k are like 6 fire hoses spraying all out........lol.
, but reason is that I didn't want to run a return line back from the fuel regulator back to the on board tank. Still using OEM oil injection pump as well so all that gets reused is pure gas, no oil mixed in with it.

Dave,
, LOL !!!!!!, I re-read what I posted on the VST and it doesn't sound like it makes any sense to me either without an explanation.......lol.
I will most likely paint it the same as the intake, silver. I started using brake caliper paint when painting intakes and other parts because it resists fuel and oil and its pretty tuff stuff. Spray it, let it dry throw it in the oven at 400 degrees for 15 min and allow to cool. It's now a hard baked on finish. Not that I don't like powder coating, it's just more practical for what I'm doing.
Gotta figure out mounting of the VST this week, then start with plumbing the fuel lines and EFI pump. Finished machining the VST yesterday for the fuel drain fitting to the EFI pump and the return fuel from the rail fitting, I was lucky because there were already 2 more fittings already on the VST cover. Had to drill one out because it had a check valve in it. Both need to be free flowing as one will be used as a bleed line return and the other is a VST vent to atmosphere.

I'm surprise you did not make a nice round, custom VST/slosh tank with your own fittings......

LMAO......, Tony, you a mind reader ????? LOL!, it did cross my mind but its really more work than what's needed. The XRI VST is perfect for handling what needs to be done with incoming fuel and return fuel. When its all done welded, machined and painted, it'll look like it belongs there although a nice billet tank would have been an added "BLING-BLING" feature......LOL.

Where did you get the plastic coated ball ends?

Plan B:
If your motor doesn't run like you expect it to, try replacing your spacer plate with a 300x injector plate. Mount the injectors there and plug inj holes for the MAD. I've never done this, but I do have some experience with the MAD intake and have a feeling this could make it work better.

All the experts I've spoken to said mount as follows from the motor fwd;
300x injector plate w/injectors
1" Composite spacer plate
And last, the MAD Intake w/injector holes plugged
Reasoning;
Moving the injectors further away will hurt performance, injectors need to be as close to the motor as possible.

I do know StratosVT has some experience with the Mad intake on a 300X platform. Cool thread
