Fuel filter keeps breaking

[jcarrick]

Hey guys,

So in the past 6 months I have had 4 fuel filters crack or blow the gasket out. 3 of them were Wix filters and 1 was a factory Mopar filter. Everything else on truck runs great, even when its spewing fuel everywhere, but I can not figure out why i keep losing filters. I thought it could be a sticky over flow valve causing excessive supply pressure so I put the TorkTek Adjustable OFV. I did this about 2 weeks ago and just got another broken filter today. I have searched for people with similar issues, but have not found any conclusive information on what is causing this. Has anybody had this issue or know how to fix it?

Can you post pics of the problems?

Is it the screw on style or the canister style?

I've split one wix filter. No issues since and still use wix.

too much fuel psi

What is your fuel setup?

What is your fuel pressure?

What is your fuel pressure?

Check the actual pressure. I run 30 psi with Cummins filters and no issues. I think some guys run more than that.

Much more than that. These p7100s like a lot more than that. Although I am surprised it is breaking them as I didn't have an issue with the canister units with 50 psi.

Blow the line out to the tank and make sure its not stopped up or crimped off. The stock piston fuel pump if dead headed can supply up to 300 psi of fuel pressure if I remember right

This^^

If you are cracking fuel filter housings with the pressure imagine what it could be doing to your p7100...

 

[jcarrick]

It is a canister style and completely stock system other than the new Tork Tek OFV. I will check and make sure there are not restrictions in the fuel lines. Would the truck run ok if there were restrictions? It never stops running good, just starts spraying fuel everywhere

It will run fine until a lose of pressure

 

[jcarrick]

Checked the lines and they are clear with no obstructions. Could a plugged up fuel heater screen cause this?

You're saying you have not looked at it yet?

Is the stud in the FF housing tight?

 

[jcarrick]

Last time I installed a filter it was. I also replaced the gasket on the stud every time
