I get my hands on a good deal of pitco and alot of issues i get involve the stainless hose from the pump to the 3way valve leaking.

Some ive been able to shine a light through the inside and see the light througb the braiding

For a temp fix i have been able to wrap the hose in foil tape.

I see this thread is a few months old, and I hope the problem has been resolved by now... however I wanted to weigh in as I have worked on a ton of fryer filter systems.

When I arrive to diagnose a filter box not pump, the first thing I do is make sure the motor is turning (it seems to be in your case)
Older frymaster fryers have the suction pipe in the back that normally has a few O rings on it. The next step is to take your finger and attempt to plug the pipe with your finger while it's running. It should have a strong sucking action. If it doesn't the issue is NOT in the filter box, and is in the plumbing of the fryer. You will need to test at various points until you find the clog. If it IS sucking, then the problem is somewhere in the filter box, or where the box connects to the rest of the fryer.

Air is thin, and oil is thick, and if there is even the slightest air leak in the system, then trying to get oil out of the box is going to be like trying to drink a milk shake with a hole in the straw. Sometimes those L shaped bibs on frymaster fryers can get bent over over time and not make a good connection.

Also, don't forget, the pump can't suck oil if it has nowhere to go. Make sure your ball valve is opening behind the vat when you pull the switch to engage the pump.

Replaced pump on my fryer system and it is working fine.. I knew the pan was ok because I tested it on the fryer system next to it.. With new pump it actually does a better job than the one next to it..

No it does not.

Actually we have a service contract with them. We pay for all the parts. So they don't care what we spend as long as we fix it. LOL

Does it have the check valve in the bottom on the inner pan, so when you lift the pan out of the base, the check valve closes so the oil does not drip out of the pan. It also has that pin in the center of the hole in the outer pan.

If it is that style, I have had problems where the frame gets deformed, so the outer pan is bowed down in the middle on the bottom, and the pin in the center of the hole does not sit high enough to push in on the check valve when you set the pan in.

Good techs don't replace part after part until they find the problem. There are exceptions but a filter ain't one of them.

If your fryer was made in 1998 or before it takes a two pan assembly. If it was made in 1999 or after it take a one pan assembly.

Yes it did correct the problem. Works like a champ. Everything was just so worn it wouldn't make a good seal. It
Was an expensive fix ($900 for a two pan assembly) but the only fix. Hope this helps your issue!

Was just wondering if new pan fixed your issue. Im having a similar issue with a 3 pot system. I have cleared the lines and removed pump. Bench-tested pump and all checked ok. Reinstalled, it worked for a while, now I am having the same issue of oil not being able to return to pot. Like you it has excellent suction, new rings, seal seems to be good between pan and fryer.

I just ordered a new inner and outer pan. I'll let you guys know how I make out. The nipple on the inner pan an the hole on the outer pan are really worn and disfigured. I believe this is where I'm getting my air. We'll see if new ones take care of it. For $900 I hope this is the fix

After you slide your pan over the inlet where the two o-rings are take some saran wrap and wrap the inlet connection good and tight. Now try it.

I'm getting suction. It's got have something to do with the drain pan. I put a hose on the inlet fitting and stuck the other end in the drain pan. It sucked the oil like nothing. I must not be getting a good seal between the pan fitting and the inlet fitting. Not sure what to do. I have brand new O-rings on it.

Place your finger on the pickup and see if your getting suction. This should tell you if the problem is in the pan/pickup or the motor/return lines.

You say it pumps air just fine. Does it have suction on the line? Sometimes you gotta take them apart piece by piece. I had something similar happen to me: As soon as I disconnected a fitting, it started pumping like crazy and I almost took a grease shower - there was a little goober of hard crust blocking a line.

All seals and O-rings are new.

Every frymaster i'v worked on doesent need priming.

As coolwhip said make sure the O'rings are in good shape. Most of the time thats the problem. Even if the O'rings look good they are probably flatened and not sealing.

Did you ask? how are the O rings and seals?...are you sure that its not sucking air?
