Do you have return style fuel rails or returnless?

If you have retrunless style rails, you can mount your FP regulator back by the fuel tank and run a very short return line from the regulator to the tank. Still measure FP at the engine though.

That way you have one fuel line running from the tank to the engine, with all the simplicity of a return style fuel system.

That's the way I plan on doing it anyway...

 

I have a return type fuel line setup and the stock fuel lines.

 

Looks great.Keep up the good work.

 

Well, there are a couple of ways to go about this.

1) you block off the return on the fuel rails and plumb the regulator in a loop around your pump, like I mentioned above.

2) You bend up a return fuel line the same shape as your feed line. Then either poke a hole in your tank for the return, or you Tee into the fuel line on the inlet side of your pump, and make that your return point.

There are 2 ways you can make a regulator work.

1) Pressure blow off. You put the regulator in the feed side of the line and any excessive pressure is dumped into the return line.

2) Flow restrictor. You put the regulator in the return line and it acts like restrictor to increase pressure, and reduces restriction to lower pressure.

Both ways can use the same regulator as long as you get your ins and outs hooked up right.

Hope this helps. I'm not the best as explaining myself, so if you want some poorly drawn cartoons from paint, I can do that too.

Thanks Adam, I'm going with number two. I have both lines returning to the tank and I'll tee in at the inlet.

 

Not sure which of those two 2's you are saying that you plan on using, but there is really only one way to plumb a return style fuel system properly, and that is to use the regulator after the fuel rails, and to plumb the return line into the tank as far away from the pump pickup as possible; mine is brazed into my fuel filler neck. If you just tee the return line back in to the pickup hose, you are going to be running hot fuel into the pump again and it is just going to vapor lock.

This is not necessarily true. A sumped tank often dumps the fuel back into the sump area to make sure the sump doesn't run dry. This is the way the Glenns Performance tanks are plumbed and there are a bunch of folks using them without problems. Plus you can always add an inline cooler if it gets to be a problem. There are VERY FEW situations where there is only one right way to do things.

Oh Culman, I run a SPAL controller to the e-fan. Lets me set the on and off temps and modulates fan speed based on water temp rather than just an on off. It was like $65 or so. I am running a Mark VIII fan.

 

Thanks for the heads up. I will remove the tank and have the return brazed into it.

 

My buddy from work stopped by in his 49 F1, Lotta trick stuff, trying to talk him into a mod motor conversion. Got the wiring almost complete and the power steering lines as well. I have the lelectric fan wire ran over to my junction point but I don't see where it hooks up on the pin out. Anyone know what controls the electric fan? Culman

 

Nice F-1. What year is your F-100? I have a mate who is putting a 99 Cobra in his 49. He was going to put in a Brand X but liked the look of the Cobra in my 55 F-100. It has been on the road for two yrs and 26k miles including a trip to the Nats in Tenn and a trip to Anchorage. Now it's torn to bits waiting on my painter and for me to finish the new motor. The old one will go in a 95 Ranger I just got. I can't help myself. I just have to stuff one of these 4.6 motors in anything I see.

 

Its a 53 F100, there are a few more posts of all the work done, It's tubbed , ford 9" detroit locker, 4 wheel disc. It's almost done, just doing the wiring andfuel lines.

 

BTW, can you post some under hood pics of your swap? I could use some inspiration
