Would it hurt to add an inline fuel filter on the frame rail between the tank selector valve and mechanical lift pump?

Thanks Bob

 

possibly yes.if you encounter water in the fuel it could potentially gell there if not heated.the oem filter up in the engine bay is all that's required to protect the ip and injectors.it's good for 4 years or 60k miles.whichever comes first.

if you really want to step things up,you can install an electric duralift fuel pump and remove/block off the oem pump.then you'll have instant prime all the time as long as the fuel lines before it are good,get a stainless screen/pre filter your after and a check valve keeping fuel right there.that's the way to go.i wouldn't put an idi engine into service without doing this.screening out the larger stuff probably will keep the fuel filter good for 100k intervals (but i bet a nickle you'll replace it due to poor quality fuel long before the miles are up......i always do.)

 

Nothing wrong with running an inline filter. The clear plastic ones make it great to see what's running through your fuel system. For the cost of a new pump and injectors, why not add one more line of defense? I ran mine on the fender with a shutoff valve, which makes any fuel system work much easier since the fuel can't bleed back.

 

What are you trying to accomplish? I added a clear screen inline filter to each tank line prior to the tank selector valve. My tank pick-ups were broke and I replaced them with a piece of fuel line. Worked great except without the screen on the pick-up debris can get lodged in the selector valve....and they aren't cheap. The screen filter prevents this.

 

old tanks = pre pump or pre tank selector is a good idea. a 50 micron screen type for tank debris should be good.

 

WOW! Thanks for all the replies. I was just curious about putting an extra filter in the fuel line.

I am eventually going to lift up the bed to check out the rear tank. When I bought the truck the guy said the rear tank had a hole in the top of it. I haven't used that tank for the obvious reason, water contamination in the tank. And while I'm under there I'm going to check the pick up in the front tank since it ran out and wasn't quite to empty yet. Thankfully it was on the trailer in the guys yard coming home with me!
