1998 International 4700 DT466e - Fuel pressure test (*UPDATE - IT RUNS - SEE VIDEO in DESCRIPTION)

40psi is enough to start. We're getting 47psi. It drops off quickly to 25psi when cranking stops. Maybe check valve on fuel rail tank return is hosed (no pun).

Wow yours cranks so well. I have a 3800 with a dt466 and it cranks much slower. How many batteries do you have? Cranking for more than 60 seconds kills my batteries

[@ridercrossing3789]

I have just 2 batteries but this one cranks better than the others I've had. And once I sorted the fuel pressure and HPOP, it starts really quick. The DT466e is my favorite diesel engine so far.

If I understood you correctly you may have described the fuel flow backwards. I think there is an arrow on the lift pump .. wouldnt the suction side be the side with the arrow pointing leftwards? or the right side of the lift pump?

Que tal soy de Chile y llevo 8 meses con un camión parado. nadie encontró la falla,lo lleve al concesionario lleva 2 semanas y ayer me avisaron que arrancó el camión o aceleró levanto rpm. pero al momento de retirar la presión ejercida en el tranqur de combustible se detubo nuevamente . alguien que me pueda ayudar a falla es similar ala que están planteando saludos esperando alguna respuesta

¿Ha comprobado la bola de control del filtro de combustible? También verifique el filtro pequeño en esa bomba principal manual en su conjunto de filtro de combustible. Esperemos que el tuyo sea una solución fácil.

[@19999927]

did you get it started? What was the problem when all was said and done? I have a truck same engine and setup.. and the lift pump seems to be doing nothing.. I replaced the pump with a chinese one and still no pressure buildup. The cam that drives the pump is rotating and appears to be bumping the pump with small 1/4 to 1/2 inch strokes. still no pressure.. pressurizing the fuel tank with 10psi shop air.. sends fuel out bleed port and pressure check port.

Yep - the main culprit was the Ferry Plug Ball. That little .25" ball kept the HPOP from building pressure.

[@19999927]

@@davidpaterson6271 Where is the ferry plug ball located..? is it easily accessable? this could be my problem.. I cannot build pressure, the fuel is all leaking back into tank via return line..

[@19999927]

I found it, thankyou, by searching google.. many thanks and God bless for a excellent video

@@19999927 if it’s fuel going back to the tank, check your manual pump check ball. It’s located on the fuel filter housing under a plastic top (has a plus sign on it). That ball is .5” and you can get them for five bucks at McMasterCarr. Part number 3645K5 Viton Flouroelastomer Rubber Ball.

I have a 2001 freightliner dt466e and I wanted to know if you know the power steering fluid type?

[@ridercrossing3789]

I'm a big fan of Lucas Power Steering fluid. Lucas even fixed a small leak in my 4300 shuttlebus. Any PS hydraulic fluid will probably be fine. Follow the lines from your power steering pump to the power steering reservoir. Fill it to the fill line indicated. If it's run dry or you're replacing the pump, you'll need to bleed it so the fluid doesn't foam up when in use. I've never had to bleed one but if I do, plenty of youtube vids on it.

[@davidcole772]

You had better relearn your fuel system comes up the fuel line to the strings through the strainer then passes under hand pump bypasses filter housing comes out lower line going to lift pump passes through lift pump comes out left side returns to rear port on housing down through outer filter holes passing over to center tube up through middle of filter to centerport to injectors that is the correct passage of fuel
