Neil Barlow Posted May 16, 2020 Author Report Share Posted May 16, 2020 We have no plastic heat spacer, we didn’t get a single drop when we removed supply hose to the carbs. We’ve had the car 6 years and have not changed pump in that time. wendy Link to comment Share on other sites More sharing options...
Neil Barlow Posted May 16, 2020 Author Report Share Posted May 16, 2020 There doesn’t appear to be a blockage as hubby has blown up hose and can hear bubbles in fuel tank 🤦♀️ Link to comment Share on other sites More sharing options...
DanMi Posted May 16, 2020 Report Share Posted May 16, 2020 I would put the top back on the pump connect the pipe from the tank and the operate the lever manually you should get a good squirt of fuel with each pump. If you do then the pump is basically fine. If not then there is either a blockage or the pump is not working. There are kits available to repair or buy a replacement. Also try with the fuel cap open as a blocked tank breather could cause pressure Link to comment Share on other sites More sharing options...
yorkshire_spam Posted May 16, 2020 Report Share Posted May 16, 2020 I can't really see clearly on the photos - do you fuel hoses have over-braiding? Are they in good condition underneath? I've had dry carbs/fuel lines due to a perished hose allowing the pump to pump air instead of fuel. Link to comment Share on other sites More sharing options...
Neil Barlow Posted May 16, 2020 Author Report Share Posted May 16, 2020 Just going to try that now, the hoses are braided and in good condition, thank you everybody. All help appreciated, Link to comment Share on other sites More sharing options...
dougbgt6 Posted May 16, 2020 Report Share Posted May 16, 2020 This is the insides of the pump 520215 is the thing likely to be punctured and what comes in the service pack Link to comment Share on other sites More sharing options...
Neil Barlow Posted May 16, 2020 Author Report Share Posted May 16, 2020 Absolutely nothing spurting out at all and the fuel filter is still empty so I think we need a new pump. Done with fuel cap open and closed Link to comment Share on other sites More sharing options...
Neil Barlow Posted May 16, 2020 Author Report Share Posted May 16, 2020 Ok, thank you ever so much for your help Link to comment Share on other sites More sharing options...
yorkshire_spam Posted May 16, 2020 Report Share Posted May 16, 2020 Before chucking the pump... do you have a fuel can and a length of spare hose? Just to test it off the motor by operating the level yourself. I'm deeply suspicious of braided fuel hose and what's hiding under the braiding. I think you are probably right, but before committing to a spend on a pump it might be worth a check. Link to comment Share on other sites More sharing options...

KevinR Posted May 16, 2020 Report Share Posted May 16, 2020 When you say that the filter is empty, do you mean it is absolutely totally empty, or has a little bit of fuel in it ? there is a big difference in the diagnosis between the two. how much fuel is there in the tank ? if it’s more than half full, disconnect the fuel pipe before the filter and lower the pipe as low as you can - you should get fuel flowing out of the pipe - if not there is a blockage in the pipe from the tank.

I'd agree on an earlier Spitfire, or a car that's been running recently, but if the fuel pipe is dry it won't syphon past the high tank pickup on a 1500 until you give it a suck.

I'd try just that but with the fuel filter removed. It may be that the pipes have collapsed; it's happened to me before. Try the system with no filter and see if it improves things. (It's hardly been fitted back to front... you can blow into the pipe and make bubbles in the tank, but the fuel won't flow in the opposite direction?)

Neil Barlow Posted May 24, 2020 Author Report Share Posted May 24, 2020 Hi, We would like to say a great big thank you to all that advised us, especially Pete Lewis who spurred us on and encouraged us to keep trying when we were frustrated and about to give up and go to a garage, and Doug who made it really simple. We have fitted a new fuel pump today and our Spitfire is now running. Thank you again, Wendy Link to comment Share on other sites More sharing options...
