Fuel Pump and Filters

Hi all
Thanks in advance for your help.When I first got my truck the lift pump slowly got petrol to the carbe, the engine would fire straight away and ran nice.Question one is there a one way valve that you can get to hold the petrol in the petrol line to make easy for the starter motor?
Q2 Is the only way to do this is to put an electric pump on?
Q3 If it is would I have it running all the time?
Q4 A friend of mind was getting a road worthy. He fitted an in line plastic petrol filter and he was knocked backed- they said it had to be metal. Has any one heard of this?
Cheers Fill

You could try one of those bulb primer pumps like boat tanks have in line I know a bloke who has done this says it works really well as for the filter have't heard of that one but I had noticed most of the Z15 and !4 filters recently have been metal although the transparent ones are good as you can see if they are full of dirt and replace them before they cause trouble

Fill, The couple of those Electric pumps that I have, have a pressure switch in them that when the line is full they stop pumping, once the Motor starts & the pressure drops they start pumping again...
As for being knocked back for a Plastic inline fuel filter, Sounds Like BS to Me.But considering the Nanny state we now live in.
Who knows..

Hi Fill, I like your project and have been following your progress to date. Seems the fuel running back or just drying out is a bit of a problem with our older trucks, you can get a valve to put in the fuel line. I bought one off a diesel injection shop for my truck but ended up fitting an cheap electric pump back in the chassis rail near the tank. It is now good to start after sitting a couple of weeks and seems to solve the problem. My truck has a hand primer on the fuel pump but being a Commer cab over it was a pain to get too. Hope this might be of help to you Cheers Hommie.

You could probably just fit an inline ball-valve tap down near the tank, turn it
off after parking. You just have to remember to turn the fuel on before starting next.

After all the pipe work I have done over the last 26 years of owning the hydro farm I would simply go to my irrigation/plumbing supplier and fit a brass non return (check valve if you like) in the fuel line. Cheap and effective, will not allow drain back to a lower tank level

The valves in your lift pump should stop run back. If they are not sealing then the pump is not working as well as it should so a quick overhaul of the pump should cure all the issues really.

Hi all
Thanks for all your replies. I did not know that you could get a one way valve. I had a look on Ebay- they are very cheep, I also had a look at inline filters- there were some glass ones.Has any one used these?
With the tap idea, that would add a bit of security.The squeeze pump was thinking out side the square- I like that.
Thanks again for all your input, you have given me a bit to think about.
Cheers Fill

Fill, just don't go too cheap if you go the one way valve, make sure the seal is suitable for petrol as many cheap ones will cark it within days, even allowing bits of seal into your pump.
Another thing is that they are spring loaded, for your application you don't really need the pump to be "fighting" the spring, just screw it open and chuck the spring, will still work fine if you install vertical or near vertical.
I like the security aspects of the ball valve but just know that one day I would be going somewhere in a hurry and forget you know what, leaving me stuck, red faced, in the middle of the first intersection with a double trying to bend his way around me, I am sure you can get the word picture.
That is where an electric pump would come into it's own.
I have an old Toyota ute which is prone to breaking the arms off the fuel pump (design fault, I have done 3) at the wrong moment, last time was on the gateway with a semi hot on my arse at 100 kph. Fortunately I knew immediately and had somewhere to go. Fitted n electric as soon as it came off the tilt tray.
Someone in years ahead is going to be scratching their head when they rebuild it, when they pull the sump off and find the 3 arms in there !
