    7.3 idi fuel filter light but worse

    For some reason I haven't been smart enough to just hook a fuel can up as a diagnostic tool. I'll do that today, haha.

    7.3 idi fuel filter light but worse

    Fuel filter light came on; a mile later I died driving on front tank; probably out of fuel...switched to rear; used schrader to purge air; no start...must've got air into the IP and hardlines. Turn on the epump, crack lines, got it bled plenty...got back in to crank but batteries to dead to...

    Still need ideas 7.3 idi air intrusion

    That $30 pump was junk out the box; gotta be within 7ft of the tank..... It's a super cab long bed dual tank truck... So I put it within 7ft and left my other epump up in the engine bay; still pumping partial air into the housing.. I guess I've officially narrowed it down to tank pickups or...

    Still need ideas 7.3 idi air intrusion

    I don't know how to check that; if I plug my vacuum gauge into housing return I get 2 or 3 psi, can't even tell its such a small number. But for $30 I have a 4-7PSI diesel rated epump coming today maybe that'll do it. I mean...the IP and Returns arent sucking fuel out of the filter; its...

    I was mistaken; my epump is 3-6psi.

    It does the clicking when I pull the wires off it and on. Using a stronger epump is an interesting idea; **** a fuel leak just add more fuel, I like your thinking.

    While you're here; anyone know the name of the grommet style orings that are in the filter housing's inlet/outlet..where the hardlines cap to the 90s.

    7.3 idi fuel filter light but worse

    yeah so it didn't lose prime over night; clear hose between IP and driver's front injector still has no air. I put 5gal in the front tank and switched back to it; symptoms persist. Must be the TSV or the IP I guess... A stuck injector would show in the clear return lines, ey? And the TSV...

    7.3 idi fuel filter light but worse

    Also; probably died cuz front tank ran out and the gauge was wonky from selecting tanks recently. I bet that's all it is. Thanks for everyone's help; I'll be back ******** tomorrow when everything else breaks.

    7.3 idi fuel filter light but worse

    I had kept my OEM caps and just did vitol 111 orings or whatever 3months avo...but pulling them off to do orings again my OEM caps finally broke at 218k odo..so gotta do what I gotta do; you'd think an air intrusion would bubble in the clear back toward the IP yeah? They were pretty high...

    7.3 idi fuel filter light but worse

    I guess I am a little lower pressure than I should be by the time it dies. The fuel heater is new, o ringed, and gasket makered just in case..works good. The filter is on more than hand tight; the inlet and outlet are tefloned; everything at the filter body is tefloned; the sensor, the...

    7.3 idi fuel filter light but worse

    Update.... So I swapped out the return caps and oring, all the hoses and clamps...tried hardlines with and without Teflon; they bleed fine. Put 3/16th clear between the IP and the drivers forward return line...no air intrusion. So perhaps I did have air to begin with but now it doesn't seem...

    7.3 idi fuel filter light but worse

    Well I've got clear b4 the epump, which has no air. Guess I need it after; I've got new return kit coming tomorrow cuz it's only $30, I mean that's all there is, if it's hard lines the diagnostic for that is to do the returns brand spanking new first, and if you've still got it then its...

    7.3 idi fuel filter light but worse

    Sucking air from where, my man? My return caps and lines are all new, less than 6 months... My filter is new... Everything is Teflon taped, even. Think I'm sucking air in my tank?... it primes quick and easy with the Schrader...... After the epump is filter after filter is hardlines and...

    7.3 idi fuel filter light but worse

    Fuel filter light came on; truck died pretty quickly after. On the road, so took it off dumped it put it back on, primed it, tried to go. Nada. Ran the batteries dead. So I got a tow and a pull strat; took 2 pull starts to start and ran rough, some injectors popping, heavy whitish smoke...
