I have the old fuel reservoir removed (sitting on the work bench) from my 86 F150 302 EFI, I have a new NAPA Gold fuel filter, same as the Wix 33268 Filter, was $10.99.
Problem is, I can not get the old housing apart. I had it in the bench vise and tried a C type oil filter wrench. I'm sure I'm going to break the plastic if I use much more force.
I see Tasca Ford has the E6TZ9K044A for a $59.00.

This being Saturday, should I wait until Monday to call them and verify they can still get this or just have anyone ordered one of these from them recently ?

Or,
Is it easier to buy a 3/8 inline fuel filter to connect the two blue lines together, NAPA showed me one in "5/16" that would fit in, which is the correct distance/length, I'm sure there is a 3/8" out there, but I'd still have to figure out the return line connection, which is 5/16".

I'm in no hurry as this is not a DD. I may be just need to be more patient...LOL

The 1/2" impact gun made fast work of removing the two mounting bolts through the frame. That was after the plastic snapped away from them on the first try to break the filter loose.

 

I think I would try a little heat but not an open flame, from a heat gun and see if that will get it.

Is that return from the motor back into the filter or filter back into the tank?

The 5/16" return line comes from the engine on the lower right side of the housing then out the left top 5/16" port to the tank.

The blue lines appear to be 3/8" coming from the tank at the lower left side then out to engine from the upper right port on the housing.

Blue is feed.
Gray is return.


Heat gun, my son has that a 30 minute drive away, I have a blow dryer...?

 

I think I used a strap wrench or a large pipe wrench, I can't remember. But you need to keep this thing in there. Ford calls it a "fuel reservor" for a reason. I was schooled by another poster that this keeps the engine fueled at all times since the fuel tanks do not have baffles in them. Makes sense to me.

The hard part is getting enough grip on the plastic, without pinching it too hard making it more difficult to turn. But I finally got mine moving.

 

That fuel reservoir thought makes sense, good point.

 

Or dose it
You have the pump in the tank making psi right?
You say because there is no baffling they use that.
So tell me if the pump is not making psi how dose the fuel in the reservoir get to the injectors way up front on the motor?
I see it as soon as the pump can't make psi the injectors won't get fuel so how dose this work?

FuzzFace2, The high pressure pump is after the fuel reservoir and at the bottom of the firewall. Remember this F150 is EFI.

This system has an in tank pump and a in-line pump. https://www.napaonline.com/en/search...=nol-veh-conds

 

Just spoke with a Parts Rep at Tasca Ford in RI. He checked and they can get the part, it will take a few days for them to get it from the warehouse, then ship it.
He did say they can get most any Ford Part for these trucks.

With tax and shipping, its about $78.00

 

I was think in tank only

I would imagine it would only keep the psi up for a very very short period. I remember the SVO mustang I owned used to have a gizmo on the fuel system, and I read in the manual it was some sort of "cushion" to smooth out the pressure spikes from the pump. Who knows?

 

FWIW: On the 1986 EFI, the tank pumps pump at about 3psi into the reservoir portion of the dual purpose reservoir, the part we're discussing here. The high pressure pump runs for a few seconds when key is turned to on then shuts off. When the key is rotated to start, the high pressure pump resumes and stays running if the truck starts. If you crank and no start the high pressure pump will again shut off until you turn key to start again. The high pressure pump provides 30-45psi at the fuel injectors depending on application and pump condition. The FI pressure is regulated by a vacuum assisted flow (pressure) regulator. At idle, high vacuum, the pressure is lower. At wide open throttle, low vacuum, the pressure increases. excess fuel is routed from the regulator back into the dual purpose reservoir. Excess fuel delivered to the reservoir is returned back to the tank.

 

Update from Tasca Ford, " your recent order has required special ordering, but should be ready to ship to you soon. Your complete order will be shipped as soon as the special ordered items arrive at our warehouse (in about 3-5 business days)."

Nice to get updates.

 

Update time, Mailman delivered today, Picked it up from the door step at 12:15pm, took picture, lubed the tube ends with Vaseline, put anti-seize compound on the two mount bolts, got cardboard and tools out of the shed, installed the reservoir, took the truck for a 5 mile test drive and was back home in the house by 12:50PM.

Engine now gets all the fuel it requires when I put my right foot down.

 

Good one! I wish I had bought one of these instead of a front tank filler hose. They are approximately the same price.

 

Have you seen my "HowTo" in that Forum to replace the fuel filler hose ?

I have been following your thread.
