Thread: The Ultimate FC

I have one on the Studebaker 6x6 as a back up and a primer.( mounted 3/4 the way up the side of the fuel tank)
I am also worried about the ethanol playing up with fuel pump diaphrams never designed for it.( and being stuck on the side of the road)
I find if the fuel is on the pressure side of the electric pump they will pull though a prime quickly.
If the vehicle has been drained of fuel or left for such a long time that fuel has completely drained pass the pump and the pump has to pull everything though from stratch it will be slow and make a lot of noise and banging etc, but will get the job done eventually.
I have portable 12 volt cube type electric fuel pump to fill the stalwart from jerry cans as the petrol filler cap is 3 mtrs high and is slow , but saves the effort of climbing up with a jerry can and holding it in place on the side of the stalwart.
I also use the portable 12 volt pump and CAV filter to drain forklift fuel tanks etc at work before I weld on them, but stranglely that fuel somehow finds it way in to the stalwart.
It can some times take much noise and time to prime.
I run it from a jump starter battery.
It should be noted most forklifts in my area run of LPG, so any petrol I find in the tanks of trade in forklifts and the ones I work on I am not ripping anyone off.
I will post a picture later of my portable set up.
It should be noted the electric fuel pumps should have some sort of filter before the pump as dirt can get under the ball valve and cause leak back of the fuel all the time leading to slow priming .
.

Don't know if one of these would be of use... Fuel non return valve in the bigger 6 pot Massey Fergies.. We have them on the shelf at work, and I found this picture from Waga Tractors of the same thing. Any Massey/Agco dealer should have them in stock.. A few in you're fuel line might help your cause no end..

Not much going on and I have other projects to do.
Winter and short days( lack of daylight after work) has been stopping me working on the beast.
Made a alloy adaptor place to fit the CAV fuel filter instead of the Volks item.
A very easy mod.
I may fit the electric back up fuel pump near the standard mechanical pump or near the fuel on/off tap behind the cabin as these locations are much lower for priming and easier to run a ignition low tension wire to.
The drain pipes for the rear tail lights are corroded.
I am in the middle of replacing them while I am paint the rear sides of the hull and playing with the water jet buckets.
The tail pipes of the water jets are made from stainless steel.
The brackets that hold the removeable rear wheel mud flaps have been straighten and welded.

New pipe welded on, I used stainless steel pipe.
The hose is fuel delivery hose as it is resistant to oil which may be in the bilge.

That hose must be water tight.
The tail lights are lower than the deck area of the vehicle.
If the tail lights leaks, the hose drains it back into the hull.
I have been draining the petrol tank, so I can check out the fuel strainer inside the tank.
I think I may have found the intermittent fuel starving problem........check out the pic of the fuel tank breather pipe.

I finally managed to get a photo copy of a book called Strong, stout and sturdy.........a history of the Alvis stalwart.
It is the first book/article covering the stalwart I have read which seems to be accurate and well researched.
Some good pics and covers most of its uses and service history.
The Stalwart was used with a bar mine laying system and barrier mine system.
It shows good pics of bulk fuel delivery stalwarts and they seemed to have been good in that roll except for the odd stalwart catching on fire.
In the drivers books and some other info all state the winch in the bow to be used for self recovery only.
Until I read strong stout and sturdy I couldn't figure out why.
The winch and mountings are well made and appear to be up to the job.
The winch is not the problem, but the parking brake is.
The twin contracting band parking brakes work on the front bevel boxes.
Therefore if the parking brake is locked on all pulling/winching forces go though only Two bevel boxes and key ways ect to the parking brake drum.
It appears it is possible to damage the parking brake or front bevel boxes with large winching forces.
If doing self recovery none of the above applies.
Recovery of another vehicle should be OK if the operator of the vehicle has his foot on the foot brake ( the Six wheel discs)or the vehicle wedged up against a tree, so it cannot move and the parking brake is not needed.

Not much has been going on due to things I cannot explain on this thread.
I have not even been able to work on the Stalwart after work.
What has been done is the finishing of painting around the water jet outlets.
Before the cabin heater was refitted I needed to sort out the wiring under the dashboard which included repair of the engine oil level/fuel level change over switch.
Replace the rear bilge pump switch and add a extra bilge pump switch for the new non standard front electric bilge pump.
Old wiring repaired and some extra stuff fitted for future use.
