Have you tested it out yet with the 50/50 mixture to see how much better the fuel pump is working?

Not yet, I'm without turbos still. Should have them installed this week.

I know someone who had the stock lift pump flow tested and it flowed 340lph how much does this new pump flow ? Could be worth it but my understanding is the stock lift pump is one hell of a good unit. And it shows with that kind of flow

I have trouble believing that. It barely flows that with no load on the pump.

Just posting what I seen on the piece of paper 3 months ago, It showed that it flowed 340lph. Did you take the time to send yours out to be independently flow tested?

I don't want to argue but I know what I saw. If you have numbers showing different I will believe you. But I seen with my own eyes a flow test. Could have just been a freak of a stock pump but that's what it flowed. The pump that they were going to replace it with went to the wayside once the flow sheet results showed up.

What is the flow rating on the new pump?

That's a good question, I'm sending it out to be tested tomorrow, I was supposed to do it last Friday, but I broke a few toes at work.

Our test did not come anywhere near 340lph, unless I made a mistake, and I'm not above making a mistake.

Its all good I just know what I saw. Like I said it could of been a freak pump but that what the sheet said.. They decided to keep the stock pump. And made a few calls to ford to confirm and my understanding is that ford put one hell of a lift pump on the truck.

Good luck with the toes That would SUCK every time you take a step

Do you have any PSI data or voltages to go along with the 340lph claim? Just curious since we are trying to figure out what the truck actually has in it.

oh shiney, that looks like the walbro E85 compatible pump which is like 450lph iirc.

No sir I don't when we were talking about it the conversation was on another topic and just moved to that I looked at the sheet and they said they saw no reason to change the pump and we talked about some Sema stuff.
