Puglet1 Posted March 16, 2023 Report Share Posted March 16, 2023 I am going to fit Gates hoses to the Vitesse fuel system. When I removed the fuel tank bung there were small traces of a blue gel like substance on the inner head of the bolt. Any ideas on what this might be? I intend to swill the tank and blow out the fuel pipes but was wondering if this could be a potential cause of the engine losing power when going up hill or trying to accelerate hard? Once the new hose has been fitted throughout I will take a look at the carbs. Any thoughts ? Pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 16, 2023 Report Share Posted March 16, 2023 (edited) sounds like simple blue silicon type sealer i have a few tubes of ford and says contains isocyanates very blue stuff works well if the pump is sucking air you will get power loss under demand the short hose on top of the tank is the normal culprit as its hidden in the boot does it run ok on the flat ie accelerate well etc degraded hose does make the dreaded rubber slivers these float about in the fuel lines and jam up the float needle valve caused by stuffing metal pipes into fake nasty hose i wouldnt get too involved with the carbs til you have proved the supply pipework let us know and we can devise a plan when its carbs agood and well presented source of clues is Mechanical Tech Articles — Buckeye Triumphs whilst this is aimed at TRs the basics apply to most of our small chassis cars and well worth a read Pete Edited March 16, 2023 by Pete Lewis Link to comment Share on other sites More sharing options...
dougbgt6 Posted March 16, 2023 Report Share Posted March 16, 2023 When I resurrected my GT6 it kept stalling, After a long search for the culprit I found a strange pink sludge in the fuel line, presumably the remains of 20 years decaying fuel. It moved about, as sludge does and would block the line, the engine died, the sludge subsided and of I'd go again. . I got rid of it by dynorording the lines with strimmer nylon cord. After that no more stalling and acceleration much improved. It was rebuilding of the carbs led me to "Hello! What's this pink stuff in the reservoirs?!!" There was very little residue in the tank and it needed not much in the way of cleaning. On a GT6 this is easy, you can take off the sensor and eyeball the inside of the tank, probably more difficult on a Vitesse. Doug Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 16, 2023 Report Share Posted March 16, 2023 yes Doug on the Vitesse/herald you can see in the tank by removing the sender its facing you as youopen the boot disavantage is its part way up the tank and if around 1/2 full you will get an eyeful of petrol pete Link to comment Share on other sites More sharing options...

Pete An inline filter is a good idea and will give an indication of how much junk is coming through the fuel system. Otherwise checking the strainer in the top of the mechanical fuel pump can might do the same... 1 Link to comment Share on other sites More sharing options...

That's what's worrying me about my refurbished tank; I'm not 100% sure it's got a totally fuel-tight deal round the sender. I suppose there's only one way to find out...

I use one of those cheapo plastic transparent ones just before the pump and change it when the plastic gets opaque. 1 Link to comment Share on other sites More sharing options...

Pete Lewis Posted March 16, 2023 Report Share Posted March 16, 2023 on the filter idea do take care some have a diameter variety hose fit and you can end up with a restriction like small plastic spout in a larger hose if you get the drift and if hose clips are done up by a gorilla you crush the plastic fittings and more restrictions appear there are washable solid brass and glass filters like club shop and others just some thoughts Pete Link to comment Share on other sites More sharing options...

johny Posted March 16, 2023 Report Share Posted March 16, 2023 with a clear filter you might even see air bubbles coming through from possible leaks either while running or on cold start up after the syphon has been lost from the connection to the tank.... 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 16, 2023 Report Share Posted March 16, 2023 this shows the dual spout diameters and the club glass one is getting a bit pricey at £19 but its a wash it for life 1 Link to comment Share on other sites More sharing options...
Mjit Posted March 16, 2023 Report Share Posted March 16, 2023 Actually based on the photos I'd say the actual hole the fuel's going through is about the same size on both filters. I've used the disposable plastic type for years and never had an issue with the design of the filter causing fuel flow issues, even at 130kph on the French Autoroutes. 1 Link to comment Share on other sites More sharing options...
NonMember Posted March 16, 2023 Report Share Posted March 16, 2023 I've got a plastic one on the Vitesse. The dual diameter is handy for converting the 1/4" main fuel pipe to fit the 5/16" pump inlet. 😉 1 Link to comment Share on other sites More sharing options...
dougbgt6 Posted March 16, 2023 Report Share Posted March 16, 2023 When I replaced my fuel pipe rubber, (there's a small length in the rear wheel arch) I discovered the pipe out my tank is 1/4" the remainder onwards 5/16" I immediately though "Replace the pipe out the tank!" A brief attempt at turning the connection said "Your gonna mend the pipe and tank to destruction!" So, it's never been a problem and now I try not to think about it.

dougbgt6 Posted March 16, 2023 Report Share Posted March 16, 2023 I got a glass one from the club shop 7 years ago, price has doubled! You have to take it off to clean, I did drop it in the sink, but it's a solid chunk of glass and bounced. Doug Link to comment Share on other sites More sharing options...
Peter Truman Posted March 16, 2023 Report Share Posted March 16, 2023 I’ve used the plastic dual sized nozzle for years cheap and throw away but I use the one with a right angled outlet as it fits so neatly in the vertical rubber pipe coming up from the chassis and the horizontal pump inlet pipe making it tidy and easily checked for cleanliness 1 Link to comment Share on other sites More sharing options...

The car doesn’t accelerate well on the flat, a similar symptom to going up hill. It has no power, sounds like it’s being starved of fuel and cuts out. Stop for approximately 5 minutes and it’ll start again. I will focus on replacing the hoses over the next few days. Thanks for your help.
