Fuel filter housing

[02greysixer]

Still running good, no rattle. Gonna test the pumps and figure out what to do, do I rebuild the Kennedy pumps, or just buy an Airdog or FASS? I like the Kennedy pumps alot they are quiet and tuck way up high, no big gay white filter hanging down. Airdog and FASS are great systems just huge.

I just put an airdog pump on my truck and it's nice and tucked away. Can't see the filters at all. Just use the very top mounting holes in the bracket. It's very quiet too.

Sweet:thumb: I was thinking of using my Kennedy bracket since it mounts high too, still not sure what route to take here.

If my lift pump is making 8 psi at idle could it still be bad? Can it introduce air into the fuel system?

Contact John.

I'm sure he can help you troubleshoot and/or take care of any issue.

 

[JustinD]

I did, he can't explain why with the pumps it rattles? So basically only thing I can do is take apart my pumps and inspect them, and if I find nothing wrong I am going to have to try a new pump.......

I know nothing about Kennedy pumps but could a bad shaft seal on one of the pumps let air in but not be so bad to cause it to leak fuel?

That sounded better in my head but hopefully you know what I mean

I don't the Kennedy pumps have shafts, they are magnetic driven I beleive??

 

[02greysixer]

Could be, I have no clue. Just a guess :thumb:

You are correct. There is no shaft. They only have a seal where the motor attaches to the pump head and the inlet/outlet of the pump.

I have an Air Dog II DF-165 on my truck, and it tucks up very nicely under the truck and is very quiet. I changed to that pump after having the TTS pumps (same pump as Kennedy's), and I don't regret it at all.

Kennedy rebuild kits should be here Friday, hopefully it solves it and runs good?? It runs good with no pump until you get on it hard, still rattles a little, but if you pull your foot out for a while and just roll into it its fine?? Is that due to having no pump??? Im confused.

 

[JustinD]

I'm going to install a filter between the tank and pumps, they had alot of shit in them so I think that might have been why they took a shit??? Is 10 micron going to be a good filter? I have the CAT filter up front 2 micron.

 

[Noreaster]

10mic is fine, but if your going with water separating filter as the prefilter you will see more 20-30 even 50mic filters. The Cat WS filters are 10mic

Thanks AJ!

Is all that from inside the pumps?

It looks metallic. Where would that much metal come from? I guess it might be time to pull mine apart and check them.

 

[JustinD]

My Cp3 went last October, had metal throughout the fuel system, my guess is alot of it ended up here?

 

[JustinD]

I thought when the copper looking filing were gone, after I changed the fuel filter 5 times. But the magnets in the pumps held on to most of it????

 

[JustinD]

Just ordered a CAT filter housing and Donaldson 10 micron filters to fit it.

 

[JustinD]

UPS came with the stuff from New Hampshire Peterbilt!!! Gonna get it all mounted tonight, should I just put a hard pipe between them or use a short rubber hose with barb fittings again?

Not sure about the weight of filter hanging off back of Kennedy bracket...
