SD Electric Fuel Pump Question

[mjonesjr]

I will search around a little more and see if I can find what they are. I would like to retain the factory hoses.

Everything I have read said that 1 of the Super Duty pumps will be plenty for Stage 1's.

Compression fittings from Home Depot work well. A tubing bender from Harbor Freight is cheap.

Thanks for that link! I've been looking for one of these!

If you got a used a pump, see how many miles are on it. Don't get a wore out one.

Yes one SD pump will work fine with stage 1's. I ran a single SD pump for years and I had a fuel pressure gauge and it would lose zero pressure. When I put the new motor in the pressure would drop as soon as the boost gauge would go over about 15psi. I have since put a second SD pump and now the pressure holds good again.

I did get a used pump. The guy I bought it from said it was removed at 35,000 miles so hopefully it will last a bit.

awesome plans go ahead like i wanted thanks!!

Where did you all get your ignition hot from for the NO side of the oil pressure switch?

I have been thinking about getting it from the starter solenoid, but if there is an easier place on the driver side that would be great.

yeah the return factory return lines are -4an . At the b;ock the fittings are 1/8th npt by -4an

Anyone know which port on the fuel tank selector switch is the supply (to the engine) and which is the return (from the engine)?

 

[PsRumors]

If I remember correctly, the bottom metal line is the feed.

I put a check valve in to prevent the fuel being able to run backwards, it looks like it's the bottom line for the feed.

 

[mjonesjr]

Does the bottom hard line go into the bottom of the selector valve?

The reason I ask is I want to replace the rubber line straight from the selector valve to the fuel/water separator so there isn't a splice.

 

[PsRumors]

I just craweled under the truck and looked

On the selector valve, the top port closest to the frame rail feeds to the engine. The top port furtherest from the rail is the return.

The bottom ports come from the tank. I am not sure which is which on the bottom ports.

Sweet! I appreciate it.
