fuel problems

[BSHEVLIN]

i am currently having fuel problems with my Australian 2 Pdr carrier.
i still haven,t managed to work out what is wrong ?
fuel isn;t even making it to the pump it is the mechanical type.

1.fuel lines are clean
2.filter is clean
3.pump has good diafram and not blocked
4.engine starts when fuel in carby.
5.and many other ideas from ford v8 side valve owners.


anybody in the world wide brain trust have any ideas ?

and is their anybody out their who knows where i could source a 6vlt pump if all else fails in Victoria.
also seeking 6vlt fans for radiator


PS i located 4 fox/rhino armoured car chassis in rual victoria this week.

and on a Seperate propertys- many blitz,s not yet discovered by collectors ect the owners said all runners. undecided if he will sell them.

hi Brenton

Sometimes , the push rod that pushes the diaphram arm is not long enough ... I've heard about this problem from Fraud V8 owners .... Take the pump off and watch the push rod come up as you turn the motor over .. is it high enough ? Just a suggestion.. I may be wrong .

Or, it may be a leaky or weak valve in the pump itself .

A 6 volt auto pulse is what you need ... it was fitted on Ford Blitz's in Hot climates

Is it sucking air at your change over tap (or anywhere else on the suction side of the pump.)(flexible hose etc) When you say the diaphragm is good, is it O.K. with modern fuel? Wet the valves in your pump and then put a vacuum gauge on it. It should suck about 15" to 18" of mercury. The delivery should be about 2-2 1/2 psi (which is controlled by the spring) If it does that, and holds it, then work back down your lines, as per my first comments.
That should give you something to think about.

It Had A New Diaphram Fitted From A Modern Vehicle A Week Or 2 Ago. Hoped That Would Solve My Problem As The One Originally Fitted Was Okay But Seen Better Days .

Found this on WIKI refering to Ford S.V. V8 motors

The fuel pump was mounted centrally atop the rear of the engine, driven by a reciprocating pushrod from a lobe on the camshaft. High milage engines were subject to pushrod wear that affected fuel delivery, corrected by the addtion of a simple aftermarket cap to the pushrod.Mike

If you can't find the problem after checking the possibilities already given by Mike and Lynn, have a look at the pick up pipe in the fuel tank - it may well have been broken or become dislodged.

This was a common problem with the old flat heads..I used to braze a layer of brass on top of the push rod..it dosen't take much..an extra 35 to 40 thousands of brass on the push rod will make all the difference in the world..a air leak on the suction side of the pump is another possibility..as previously mentioned.
