Yeah I was surprised myself to see just how fast & forceful the fuel was coming out.I would think a stock 88lph pump would be a bit less forceful than the 255lph pump they were using,but since youve got a (if I remember correctly) stock 88lph pump in the tank plus a T-rex inline pump,you'd probably have the same amount of force,as shown in the video,occurring inside your tank also.Im kind-of surprised people don't experience driveability issues related to the turbulence thats caused at the return line.This seems especially true once the fuel level gets somewhat low in the tank.With that much force coming out,it seems like the fuel would literally be pushed away from the pump inlet at the bottom,unless maybe the filter/strainer (attached to the pump inlet) calms the waters enough to prevent this.
Yeah, I have the stock pump and a inline. I think the inline is rated at 100 and some odd psi. I kind of think the videos results are exaggerated a little because the fuel in their rig doesn't have to travel as far as if it was on the car. They're only circulating a few feet where as the return line on the car is probably like six feet. But for my test I guess it'd be similar to their results since I'll be removing the line closer to the rail.
I was thinking about disconnecting the line that feeds the fmu since it's easier to get to. But if I did that I wouldn't know if gas was going through and out the bottom of the fmu like it should. So I guess I'm going to have to rig up long hose coming out of the bottom of the FMU and into a gas can.
Do you think it'll up a gas can pretty quick?
I'm hoping the FMU line is messed up because it'd be the cheapest and easiest. It's plausible. The fmu line that goes from the rail to the fmu leaked so I replaced it with a home made job. I can't find the stock hoses so I'm going to have to pull the fittings off of the fmu hose and attach them to a length of hose like I did the other.
A new FMU is $200. I found a set of 6 42# injectors and I think singles were sold for like $30 each. I'd have to get a re-tune which would be around $300. If it turns out to be the fmu I would like to take it off and get larger injectors. But I don't know if money will allow. Here's the injectors. They're knock-offs I do believe, and a lot cheaper than others I've seen, so I'm not sure about them either. Are these stock style? Are the stock ones "fat" or "skinny?"
