Paula Posted February 12, 2022 Author Report Share Posted February 12, 2022 We've been on a few runs up to Hertfordshire and she's been fine, but recently she's decided ahe doesn't want to go over 60mph. She starts to stutter and lose power. Then she's fine again at about 40mph. I've cleaned up the leads (i thought it might have got damp from an overflowing radiator) but still the same. I'm now thinking fuel pump. One day i might actually go bloody camping! Link to comment Share on other sites More sharing options...

Another thing to check would be the fuel lines. If they are old erhonal petrol will degrade them, making them collapse internally. Link to comment Share on other sites More sharing options...
PeteH Posted February 28, 2022 Report Share Posted February 28, 2022 1970`s?, Original Tank?, has it ever been cleaned?, Intermittant issues with fuel are sometimes down to debris moving about and preventing/reducing fuel being sucked into the pickup pipe?. More so if the vehicle had been laid up for some time, campervans/motorhomes are particularly prone to it. Fuel hose, needs to be ethanol suitable nowadays, E5/E10 degrades when stored and adds to starting issues. Recently during the "fuel crisis", the only fuel available was unleaded E10 locally. My little P-107, (2006) which we "A" frame behind our motorhome, was behaving like "grumpy". Topping off with unleaded "super", improved the performance, and the next full fill (super) has improved on that. Not all "newer" cars are E10 ready. Never mind 70`s Engines.

It was the steel fuel line from the pump to the tank. I blew back down it and that seemed to clear it out. I’m thinking of adding an extra inline filter near the tank, but I’m a little worried that’ll make 3 and it might be too much for the pump.

Paula Posted February 28, 2022 Author Report Share Posted February 28, 2022 I did put a endoscope into the tank. It looks very good to me? I was also thinking of changing the steel lines for rubber. They are very rusty, as is the outside of the tank. Inside Tank small.mov Link to comment Share on other sites More sharing options...
PeteH Posted February 28, 2022 Report Share Posted February 28, 2022 Yeh, does look in reasonable nick, Looked at it twice, but couldnt see the pickup point?. That would be where any Debris might be?. (kids have been known to put crap in tanks too before today!) obviously if not a locking cap. A lot of modern cars have heavy duty "plastic" fuel lines, any "rubber" Now must be ethanol suitable (R9?). But so long as the steel ones are proved clear and show no actual leaks they should not be the issue?. MOT examiners, can and do ocasionally condemn really grotty ones as well as brake lines. The fuel and brake lines now fitted to my 13/60 are copper/kunifer with no "rubber" conectors except the tank and the Fuel pump. What type of Carburator is fitted?. I ask, because back in the 80`s, Ford had a lot of issues with a type of carburator fitted (mostly) to Mk3 Escourts, long while back now, but I think it had to do with what they termed as "emssions" reducing features?. My then, Company car, was back and forth to the dealership, it would be ok for a while and then lose power or stop, if you waited a while you could restart. In the end they fitted a "modified" carburator, (or so the young fitter told me). Pete Link to comment Share on other sites More sharing options...
Paula Posted February 28, 2022 Author Report Share Posted February 28, 2022 I wasn't happy with the carb that was fitted. It was from a different model and drilled to fit. I have just fitted a New Old Stock one. It looks very simple. Link to comment Share on other sites More sharing options...

PeteH Posted February 28, 2022 Report Share Posted February 28, 2022 Investigate all other aspects first, the simple one`s should be eliminated, but be aware that the condition of the box is an indication of the storage conditions, (age/heat/cold/humidity etc;) and may have had some effect on internal (especially "rubber" components). As an example of how they can deteriorate, We had very large "O" ring seals on water jackets in Marine practice. Bitter experience made the realisation that leaving them stored in thier plastic packaging accelerated their dertioration. We resorted to storing them in an old oil drum filled with talcum powder and kept in the shaft tunnel (coolest place in the machinery spaces).

The rubber seal on the accelerator pump bit looks perfect. Better than the cheap copy that came off. I'll keep the other as a spare. At least i know if it happens again i can probably clear it again. Would another filter at the tank end be a bad idea? That would make 3 filters in total. It would also give me a break in the line to clear it easier next time?

Pete Lewis Posted February 28, 2022 Report Share Posted February 28, 2022 you really dont need 3 fuel filters reliability comes from less joins (was going to say Joints ) but i know that would get picked on |Ha one main filter is all it really needs .....did it have anything as original ??? nasty ebay rubber hose is the main problem it breaks up inside and you breed rubber slivers every time yo refit it 3 filters is obstructive to full power , like riding a bike with 3 face masks on huf and puff Pete 1 Link to comment Share on other sites More sharing options...

Badwolf Posted February 28, 2022 Report Share Posted February 28, 2022 Paula - I used 8mm copper microbore heating tube for my main fuel pipe. It's lasted for 30years. You just need the bendy spring thing to bend the tube without collapsing it, but an easy job. 1 Link to comment Share on other sites More sharing options...

Badwolf Posted February 28, 2022 Report Share Posted February 28, 2022 I just used 'rubber' fuel pipe of the correct internal diameter and a couple of good jubilee type clips for joining to pump, tank outlet etc. I must replace it for E10 fuel though...it's on the list!!! 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 28, 2022 Report Share Posted February 28, 2022 that old filter has seen a good few years a museum peice club shop sell gates fuel hose the good stuff with an in lne or even a modern filter with hose connctors and you can use plastic fuel line for the whole run from tank to filter etc. no modern cars use copper Pete 1 Link to comment Share on other sites More sharing options...

However the Smirnoffs were kicked out back in the day and ended up in Paris, so they're more French than Russian. It's a sign of the times that during WW2 Russian forces had mobile stills with them, now in Ukraine they've got mobile crematoriums. Doesn't exactly instill confidence, does it?
