355 355 Spider Chasing down leak

The pressure limiting device is the 2 inch section in the middle of that line. Some mechanical engineering type will have to tell you how that was designed.

I don't know that.

I have no experience with it yet.

 

Have you validated its a PS leak? What color is fluid? The line you asked about terminates into a T that sits right under the fuel distribution block.. from there it splits to each air plenum.

There is a lot that could leak up there and drip travel down hoses.. get flung all over on belts etc.. I've seen a cam seal leak in this area that makes a large mess and gets it everywhere.

Like stated many of the PS hoses are hard or expensive to source to completely unavailable. You will have to get the cover off between the plenum boxes at a minimum to see under there. Likely get the coolant tank out of the way. It will be a time consuming exploratory surgery. Donyou habe the updated PS reservoir? If not nows a good time to get it if you are tearing into it. Be patient as you'll likely run into little odds and ends you may want to replace during reassembly and that will stall you while waiting for said parts.

 

hoses are obvious when you get an eye to them. 1 from reservoir goes to the pump. 1 from reservoir goes to a hard pipe towards front of car. There will be 1 pipe from pump to front of car. Hope it's the hose from the tank to the pump as I think that's the only one easy to get... or that it's a sloppy installed loose hose clamp. Good Luck!

I just replaced the feed hose to the pump for a crack in it.

The short one. The long one is the low pressure return line from the firewall.

that must have been a big mess ...

 

Well, Uhm, yea.... about that.

I thought I had front engine seal leaks. It was that crack and the previous mechanic not tightening the hose clamp.

Lots of "while I was in there" on this one as I started on Feb 20 and finally ran the car this past Saturday.

Those are 12 year old Fabspeed headers.

 

Oil was the concern originally. The front seals on the drive gears can leak. Not the case...

Fabspeed discussion is a different thread, but the sound is great.

 

Those look fine.

The only only other places to check for hose clap leaks are the ones that attach to the pump and the one that attaches to the firewall.

Firewall is easy.

You can see the one from the tank to the pump if you pull the wheel and wheel liner.

If those are fine, then it is a pressure side leak and may be the line from the pump to the firewall.

In fact double check that that coupling is tight. 17mm wrench on the tube. 22mm wrench on the pipe / hose.

 

May not be your leak but those hoses aren't on far enough for my taste. Clamp may be on the barb. Agree check all the fittings. Between this and the brake line looks like an engine out reassembly in haste. Check everything and assume nothing.

 

Teflon . Scary.
