I'm looking at replacing my stock fuel system and going electric with frame filters. I know I need a fuel pressure regulator on the return side of the heads, pressure gauge and set to about 68 psi. Has anyone used the fuel restriction sensor in their replacement systems? If so, where do you put it?

Thanks.

 

Nah....no need for the fuel restriction sensor.

 

Thanks Bill. I'll just make sure to change my filters regularly.

A reason I was asking is because my fuel filter light came on two days ago. I believe this sensor is what causes that.? I changed both the on engine filter and the add on frame filter. It ran fine at home, than 7 miles down the road the fuel filter light came on again and than the engine sputtered and died. Figured my lift pump failed. Was looking to replace the hole system anyway and figured this would be as good a time as any. Looking for the quicker starts and power. But I did locate the source of my fuel starvation. It wasn't the lift pump. It's the fuel tank selector valve. Somehow it's clogged up. Could not blow air back into the tank through the valve, but could on the tank side of the valve. Am bypassing the valve to get the truck going again.

Thought if I put the restriction sensor somewhere in the system if would at least give me some warning.

 

I didn't install one.
I do remember seeing someone put a mechanical gauge one the filter/pump assembly that would indicate vacuum on the first filter. It was supposed to be an indicator for when to replace the filter. Seemed like a decent idea

 

Yeah, I've seen some of the more expensive efuel systems with a delta P gauge on the pre-filter. Good idea but you still had to crawl under your truck to read the thing. Plus it's one more part underneath the truck to get broken off or leak.

I'm working on my efuel now and I plan on putting a fuel pressure gauge in the cab with the sensor in the line to the engine (once I find a place for yet another gauge). I think I'll be able to tell if the filters start to clog by a slight drop in fuel pressure.

 

I have an in cab fuel pressure gauge. More info than just filter condition from one monitoring device.

Too much over complication for for a normal maint item. Just service the truck properly.

 

I think the in cab fuel pressure gauge will also be useful for troubleshooting. For example if the truck won't start, it helps to know if I have good fuel pressure or not. Plus, with all the instruments, the inside of my cab will start looking like an F-16 cockpit, kind of cool - or maybe not!

 

Or you pop a fp fuse the gauge is priceless. But if you run out of fuel by the time u see the needle wain it's too late already.

 

If you want a fuel pressure restriction gauge, a simple solution is a mechanical spare filter minder gauge similar to the one right off your air box. You can run in line and simply see what your vacuum is. It's a good visual indicator.
