MKTR Posted June 25, 2018 Report Share Posted June 25, 2018 Hi Guys, In 2015 I posted a problem regarding fuel starvation and multiple breakdowns in my TR4, which all seemed to be related to ethanol and rubber perishing. As part of the remedial measures I had the petrol tank out & flushed it, then sealed it with 'slosh', I fitted ethanol resistant fuel lines and fitted a new petrol pump diaphragm. All has been well with fuel since 2015 until this weekend. I broke down twice on a long journey with the same issue - complete engine stop. Rubbery lumps in fuel pump bowl and something evidently blocking the tank outlet as no fuel was flowing when the pump inlet was disconnected. I remembered the advice to blow back up the lines from pump to tank; and fuel flowed again. The greyish lumps in the fuel bowl look like sealant/silicone when out of petrol but like a jelly fish when suspended in petrol. Before I have the petrol tank out again I wonder if anyone can suggest where this substance might have come from. Tank looks clear of rust, paint flakes, crud etc and I do not recall using any sealant on the pipes or the sender unit. Also, has anyone ever managed to come up with a cunning way of retro-fitting a wire mesh over the tank outlet to trap any roaming bits and avoid complete pipe blockage? Many thanks, Mark Quote Link to post Share on other sites
RogerH Posted June 25, 2018 Report Share Posted June 25, 2018 Hi Mark, when you 'sloshed' the tank did you use the latest E5/10 resistant variety. Roger Quote Link to post Share on other sites
ChrisR-4A Posted June 25, 2018 Report Share Posted June 25, 2018 Hi Mark, I made the outlet pipe so it sticks up into the tank about 4 ins. The top of the pipe is flattened leaving only about 1mm gap and between the top of the pipe and just above the tank fitting I drilled about 15 holes 4mm dia radially and staggered so theres always plenty of ways for petrol to enter the pipe.

MKTR Posted June 26, 2018 Author Report Share Posted June 26, 2018 +1 Pete Good thought. I hope I did use the ethanol resistant variety as that was what I had issues with originally. Problem is where did I put the receipt!! Mark Quote Link to post Share on other sites
