3 gallons or less in your tank!!

Some pumps flow more volume and pressure than others. Depends on the brand and model.

I know Hurricane said that they had to change the regulator with their pump along with the different elbow was because the stock regulator and elbow wouldn't flow enough for the pump and it would increase the fuel pressure at idle and run rich as well.

The issue with Fords is that a longer run has more resistance thereby having enough back pressure to increase the pressure at the rail. Longer runs have more resistance not to mention the possibility of a pinch point as has been said. He was right on the edge there like he found. And from the sounds of it, sitting on the tank also added a few more pounds of resistance as well.

justinator found the new pump he's using to have WAY more pressure, and from the sounds of it needing 3/8 return fittings with a big regulator needed to work with it all too. So its a case by case basis depending on the pump, regulator and return plumbing used/needed.

Exactly Mike! This is case by case and why I suggested verifying your rail pressure after ANY modifications to the fuel system wether or not everyone else has done the same mod. Out of spec fuel pressure wether too low or too high can cause a plethora of issues. IMO fuel pressure shouldbe checked atleast every season just like boost leak testing. Its equally as important. My original post was more of a “bulletin” alerting people of a possible issue to be aware of. 2 brand new pumps here putting out some serious pressure and flow, Surely I am not the only one.

Do you see the need for 5/16" fuel line for the return for a TD Power Trail 270hp tune using the stock fuel pump?

I think this is a great question and will say two things?. Maybe 4? lol All my opinion only
1 The stock fuel pump on stock wiring with a 270 tune is probably not enough pump. ESPECIALLY any temps below 5 degrees
2 I ran 1/4" line on the stock pump AND with a TD upgraded pump WITH td 270 tune for 4-5 K Miles. No issues.

Seems the pumps capacity and the size of the fittings elbows are important..
The Stock wiring and relay size are suspect also.

I have an A/F ratio gauge so I can keep an eye on that. If there are fuel supply related issues, I would see that on the gauge.
 
Ok, so I did return line (1/4”) with a Hurricane elbow(which looks like kimpex one) the relay but stock pump. More for the starvation issue and reliability. Hurricane 270 tune. Should I have left well enough alone?

You have nothing to worry about, the stock pump does not have anywhere near the capability of exceeding the return flow of 1/4” line and or elbows. Ride and enjoy.

I see some guys saying they are using 5/16" fuel line to run to the new return location on the pump. That size appear it will fit fine on the fuel pressure regulator but would be too large for the plastic elbow fitting on the other end. What are you guys using to clamp that end down if you are using 5/16 hose? The plastic elbow fitting is made for 1/4" hose.

I originally ran 5/16 but couldn't get it to seal at the factory elbow so I switched to 1/4 fuel injection hose. No leak issues now.
 
Just for those who haven’t seen fuel starvation problems with the lighter to mid tuned!

I’ve been running the Max Spool 16, tunes for the past couple of years, first the 2 bar tune, and then upgraded to the 3 bar Max Spool 16 tune, all without fuel pickup or starvation problems!

So this season when I upgraded again, to. Max Spool 17 with the SQ 2.5”, I was told by TD that there was no need for the bigger , higher output fuel pump. Anything past that, like adding a header would require a non stock pump!

So, I decided not to install a non stock pump for now! Not saying I won’t have to, just trying to stay with stock fuel pump until mine needs it!

Im running the same max spool 17 but I did bump up the fuel pump a bit to the walbro 190. Havent had any problems but I havent run the tank down too low either
 
Got mine done today. Ended up not using the SAE J30R7 hose and buying some SAE J30R9 hose. The 30R9 hose has a thermoplastic liner (or something like that) so it won't harden with the ethanol in fuel. That hose was much harder to put on the fuel pressure regulator but I got it on by heating up the end of the hose and spraying a little WD-40 in the end.

Since people were concerned if the plastic elbow and grommet would stay in the top of the fuel pump assembly, I made a safety gaurd.

Even though I ran this for one year with no issues.
The wires do not rub on gaurd.

As hard as it was to get the elbow pushed into the grommet when using a 1/2" hole (instead of 0.52" like the one in the stock location, it would seem unlikely that the elbow would pop out of the grommet. Regardless, I may make a guard similar to yours.
 
i dont think it will pop out , if anything i think it would cut the wall of the grommet makin it 2 pieces , then that would be not good! i only think this because i added a gerry can tank to my gas generator and put this exact fitting in the bottom on the jerry can to gravity into the extenda run cap on the generator, and it split after a few weeks, i then put a bulkhead style fitting in it compatible with fuel much better , but there is no room to use that style on the winder
