EFI tank discussion

Can you monitor the fuel pressure and data-log with the pro-flow?
Then watch it as you creep up on a WOT pass.

I don't have a datalog per se without running something through the can-bus
I've been using the gauge screen and a screen recorder

Creeping up on WOT pass isn't really a thing in the car. Top of 3rd gear is still over 100mph

I have used the same regulator on the pickup and it reads the same psi.
two different style pumps, line, and pick-up configuration
(EP381, -6AN true inside of .375, TBI tank unit)
(gauge confirmed, only 52 psi max)
Moving that fat bastard is quite a fuel load

This suggests I have at the very least a soft regulator.
I fail to see how it would only go exactly 52 on both systems
 
Why not run a vacuum reference regulator and over pump it so your injector duty cycle matches?

This is what I did in my 82 for booost when I can afford it.
 
Restrictions to flow create heat, if you want to keep the gas as cool as possible a uniform diameter, and gentle bends would be best.
 
Why wouldn’t the same regular have the same psi on two different cars? To me that says it’s a good regulator. your proflow log injector pulsewidth?

Same regulator does same pressure on two separate systems. Did I word that funny? I have to go reread. Sorry if that read wrong

I do not run PWM on any Efi system

I would expect it to be the same no? Isn’t that the point of the regulator to keep the same psi output regardless of input?

Was the same. And low on both systems, thus being my issue
52 WOT, not 58

The 43 psi regulator I took off the truck was 38 against the vacuum reference and 43 WOT
And testing it in 3rd WOT is a lot easier lol
 
Holley and Tanks inc only make their tanks in 25 gallons, does anyone know why don't they make them in 31 gallons?

For a GM blazer? You can use a 31 gallon burb tank

This will need a stock sender for a 31 gal tank
 
Yes, my tank is 31 gallons,
But why does Holley and Tanks inc only make their tanks in 25 gallons?
 
25 gallons is more than adequate for most trucks unless you're going deep off the grid and need the range.
 
Both my squares have big blocks, I know the feeling well, however the street rig with a 25 gallon is more than sufficient IMO.
Yeah, in all honesty it’s only when I’m out in the desert all day/weekend.
 
I do get nervous too. I had to trail run the crew cab for a while with a single 20gal saddle tank. Only ran out of fuel once and that was on a long day if snow bashing. That did motivate me to get the other tank operational.

The daily driver c10 has a single 20 gallon tank. I never worry about running out of gas just have to do weekly fill-ups.
