It’s 10 mph off at 60 so yes, looks more like 18% off. Seeing my 2019 TRD Pro only gets 16.....
That said it does not do as well on normal around town tanks

Great weekend in the 60 enjoying my one relic with AC.
It was brutally hot and humid in Mississippi this weekend but the Ole Blue 60 go me out 2 days in a row enjoying some Mississippi backroads. We got nearly 200 miles of gravel and 300 likes of backroads under her tires without a single hiccup.

This is SE Mississippi but there are a lot of great backroads around Union Church

Little update on Ole Blue and some Fuel Injection tech
We loaded up for a weekend in the Ozarks this past weekend.
about 300 miles in and 50 miles from the Ozarks I was leading a jail break crowd of 7 Land Cruisers on I-40 going about 80 mph when my AFR Light flashed red and 35 and my truck just died.
We pulled it to the side of the road in a terrible place and then immediately decided to tow it to the next exit where we started going through the troubleshooting to see what died.
We spent about 1/2 hour checking everything and ended up just tossing all my s*** in my son’s truck and I climbed in another 60 and we took off.
Truck seemed like it was getting fuel to the Sniper but the usual prime of gas into the bowl when we turned the key was not happening.
We “thought” we tested the fuel flow enough so we determined it had to be a Sniper malfunction. I called @under_psi who was coming up the next day to bring up his Sniper and his Robbie Mac powersurge.
Weekend went great and about noon we stopped back by the 60 and started the Sniper swap.
Swapped Sniper.
Nothing.
Then we tested the PowerSurge. Dead.
Replaced PS. Fired it up. Did a quick AFR adjustment and Hauled ass.
The PS holds about a quart of gas around the pump.
That is about 15 minutes of tuning and 2 Miles on the interstate.
Dead again.
This time Lou towed me to Advance Auto.
We dispatched @WharfRat to Popeyes and started collecting parts

So now we have a new Sniper and a new Robbie Mac and we are dead. We start checking fuel pressures and we got no gas getting to the Powersurge.
Dead OEM manual pump. Go figure. It’s about 1 year old. How in the world could that happen? Who knows.
I grab a Holley 7# pump from Autozone and put it in the old spot where I had my fuel pump for the AFI on the frame rail.
Good to go. Popeyes was good.
Off we go.
Then I realized we did not bypass the manual pump......

Minutes later the truck died again. Holley low pressure pump s*** the bed trying to push fuel through the old pump.
By then I dug around and found enough hose to install my spare Walbro high pressure pump with just enough 3/8” high pressure hose and clamps to go direct to the Sniper. We kept all the return hoses routed through the Powersurge and capped the OEM pump hoses and the Powersurge Out to Sniper hose
That did it. 5 hours home humming like a sewing machine
So what does this all mean?

If you think I have the answer to what caused this chain of events, I don’t.
Basically I had all the parts In my Sniper spare bag that I move to whatever truck I’m taking on the trip to bypass the stock pump and the Powersurge. I should have just jumped to that on Friday but I did not. I just had no idea a new manual pump would die like that therefore starving the PS and burning it up.
@HemiAlex opined that the Powersurge must have killed the manual pump. I just don’t seem how.
In the mean time I’m going back with another OEM manual pump and the setup I had before. The only thing I’m doing going forward is making my in-line spare setup super easy to install.
I have 3 identical setups. I’m going to roll with what I have. If I have another mechanical pump failure I’ll be changing out a lot of fuel systems.
I’ll keep you all posted.

The pump can die one of two ways:
You lost (Stuck or broke) the pushrod and it ceases to move the diaphragm. Very unlikely.
You tore the diaphragm, causing a loss of vacuum and not allowing the rod to push/pull the assembly.
I can see the manual pump pushing 7 psi, free flow out to the carb and since it’s basically atmospheric after the pressure relief of the needle and seat in a carb...it sees no problem.
But with the power surge you’re supposed to only be filling from the pump, but I could see the suction from the power surge counteracting the motion of the manual pump and stressing it.
I’m not saying it should happen, but aside from blaming the power surge....either you got a dud oem pump or something got sucked into the diaphragm and tore it.
Did you have fuel in the oil?

Don't believe the Power Surge would ever require more fuel than the manual could provide. Perhaps closing off the mechanical pump's return is creating a back pressure problem? An autopsy of the OEM pump is called for.

It actually takes 15 minutes of tuning and about 2-3 miles at 75 mph to run the powersurge out of fuel.
No trash in the fuel filters
I never checked the oil. Will do that ASAP.

Got home from a secret mission to Mosley Motors and decided to get my mind off this 60 fuel pump.
@Racer65 sent me another OEM pump and it came in
I popped the old one off. It was full of fuel (none in the oil) and I pumped the arm and gas came out every pump until it was empty.
So damn. No idea what happened now. I sure was hoping that was the issue. Now I just don’t know. Oh well. I’ll just keep driving it and see how it behaves.

I did not crack the PS open. I sent it back to him this week for service.
I wonder if you’ve got a loose clamp and you started pulling air and lost prime while it was running hard on the highway.

We found a feed hose that may have bent and crimped itself.
Maybe.
But its still a simple system. We trouble shot it for quite a bit before I pulled the plug and we went wheeling.
Maybe the crimped hose starved the PS at speed and killed the pump inside.
Certain hoses can collapse. I like the aeroquip aqp for barbed fitting hotrod stuff.
Do you recall the grind on the cop motor cam?
