Iain T Posted July 25, 2022 Report Share Posted July 25, 2022 Gates or Cohline are both excellent hoses. It seems I've fallen foul of bits in the fuel line as I thought I had changed all the hoses but may have missed one! Iain Link to comment Share on other sites More sharing options...
Quack Posted July 25, 2022 Author Report Share Posted July 25, 2022 Inside of the tank…bad enough to cause the issue? IMG_5025.MOV Link to comment Share on other sites More sharing options...
Quack Posted July 25, 2022 Author Report Share Posted July 25, 2022 Another thing I just realised, the pipe from my tank nearly all the way to the pump is a hose, not a copper or steel pipe. The pipe ends pretty much immediately after leaving the tank as seen in the photo attached, that is just behind the back wheel (the bottom line is the fuel line) Guessing this isn’t normal and it should be steel all the way along?

Quack Posted July 25, 2022 Author Report Share Posted July 25, 2022 Another spot, looked in the fuel pump again and…see all of that debris in there! Looks like flakes of rust. Link to comment Share on other sites More sharing options...
NonMember Posted July 25, 2022 Report Share Posted July 25, 2022 The inside of the tank doesn't look catastrophic but there's signs of possible flaking, as confirmed by the pump photo. It would probably respond to the clean-etch-paint/line approach but be aware that it's very easy to get that wrong and end up with things in a worse condition than before because the liner flakes off. The fuel pipe should definitely be solid - steel originally but copper or cunifer preferred for ease - with only minimal rubber joints. Link to comment Share on other sites More sharing options...
Badwolf Posted July 26, 2022 Report Share Posted July 26, 2022 Quack - As Rob says, if you do go with the relining of your tank, Frosts do a kit. It is a 'marmite' kit... Some love it, some hate it, but you MUST follow the instructions precisely (eg. the tank must be perfectly dry) or the lining treatment will flake off in the tank with disasterous results. There is also the ever present danger of residual fuel vapour that would need addressing. Nothing that cannot be dealt with.... with extreme care.

johny Posted July 26, 2022 Report Share Posted July 26, 2022 The other option is to leave it as it is which is what Ive done. Obviously remove as much of the rust as possible but it has only occurred because of oxygen so if in future you always keep the tank full further rusting should be minimised. Then keep an eye on the filter as a guide to whats happening... Link to comment Share on other sites More sharing options...
Quack Posted July 26, 2022 Author Report Share Posted July 26, 2022 I may leave it if it’s not that bad, i don’t currently have a fuel filter so im off to pick up this today Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 26, 2022 Report Share Posted July 26, 2022 club shop sell a metal chromed cleanable filter the plastic ones do have a problem you can tighten the hose clip and compress the plasitc spout to a restriction do cut the spout off to suit the hose diameter , as they are stepped to accept 6 or 8mm dia hoses do not overtighten the clips Pete Link to comment Share on other sites More sharing options...
Quack Posted July 26, 2022 Author Report Share Posted July 26, 2022 So they are, thanks for that. Should have a new update by this evening Link to comment Share on other sites More sharing options...
johny Posted July 26, 2022 Report Share Posted July 26, 2022 Dont worry that the filter runs quite empty sometimes - this just seems to happen but the system continues to function perfectly.... Link to comment Share on other sites More sharing options...
Iain T Posted July 26, 2022 Report Share Posted July 26, 2022 I bought a cleanable metal/glass body filter from carbuilder solutions that had 1/4" one end and the other 5/16". Very handy when it came to fitting in the hose loop at the tank. Iain Link to comment Share on other sites More sharing options...
Quack Posted July 26, 2022 Author Report Share Posted July 26, 2022 Pulled out the tank to pump fuel line. Are we sure this is meant to be all pipe? It says 1968 on it which is also when my car was manufactured I believe, maybe just a coincidence. I do wonder why whoever replaced the pipes did so with rubber hose instead of an actual pipe though!

Found out months later that the fuel pipe was the wrong size but the merchant was no longer listed oh well. Might even fit it one day! Link to comment Share on other sites More sharing options...

Pipe from top of tank to first connection is rubber. It should be metal from that connecton all of the way to the engine bay. 1968 may be the date on a reel of rubber pipe or could be a spec or batch number. In my view, it would have perished by now or led a charmed life. Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 26, 2022 Report Share Posted July 26, 2022 you could use plastic/nylon fuel line as per most cars 1970 on doesnt have to be metal but rubber is too vunerable Pete Link to comment Share on other sites More sharing options...
Quack Posted July 26, 2022 Author Report Share Posted July 26, 2022 Ok finally finished installing the new lines and filter. I’m a bit concerned about these kinks will they be a problem? I also spilled a bit of fuel in the bay when unplugging the old line so bit concerned about a fire too. Link to comment Share on other sites More sharing options...
Iain T Posted July 26, 2022 Report Share Posted July 26, 2022 I just ordered some gates hose from the club shop but they are out of stock again. Link to comment Share on other sites More sharing options...
Iain T Posted July 26, 2022 Report Share Posted July 26, 2022 It should be OK for the moment. Do try and use a P clip or similar to secure the copper pipe or it'll rattle about. Also the hose and pipe look to be touching the oil filter? Iain Link to comment Share on other sites More sharing options...
Quack Posted July 26, 2022 Author Report Share Posted July 26, 2022 It is touching yeah, also here the rubber touches the engine block which makes me think if the engine gets too hot would it burn through.. Link to comment Share on other sites More sharing options...
Quack Posted July 26, 2022 Author Report Share Posted July 26, 2022 Started it up anddddd no difference…same story! Starts up with a fair bit of choke and some throttle, then rapidly the power decreases until it shuts off… only other fuel related thing I’m thinking it could be is the pump then, since I kept the same pump but replaced all the fuel lines Link to comment Share on other sites More sharing options...
Iain T Posted July 26, 2022 Report Share Posted July 26, 2022 You need to check if any petrol is being pumped to the carb. Take a hose off by the carb and crank it over, does petrol spirt out? Be careful!!! I normally disconnect the ignition system so it can't fire up and put the hose in a container to catch any petrol. Is there petrol in the filter?

They will cause some restriction but not enough to cause loss of power at idle. How did you bend the pipe? It really helps to use a proper pipe bender - they're not overly expensive.

Quack Posted July 26, 2022 Author Report Share Posted July 26, 2022 Ok! So I did the test mentioned way back, using a funnel and gravity to get fuel to the carb, and the car ran well with that, it didn’t die but I let it run for a good minute or so which normally it can’t make. while this was happening I had the pipe from pump to carb hanging off the car, and at first no petrol, then a little bit spitting out here and there but not much really. there is petrol entering the filter, so the problem lies between the pump and the carb, since it’s brand new pipe I’m guessing the problem is the pump, so looks like I’m going to be ordering a new one.
