mattjamesw Posted April 10, 2022 Share Posted April 10, 2022 Wish mine had gone smoothly!Tank out as leaking at lowest drivers side corner (ali deteriorating and pitting, patch welded), new-to-me pump replacing standard pump as suspecting the pump may have been the source of my K series 1.8 splutter and poor starting, didn't fit into the cradle so bodged it to fit, new fuel seal difficult to refit due to philips head bolts worn heads. Ran for 3 days before breaking down. So I need to take tank out and check fuel pump. I've read folk suggest upgrading the bolts to hex-head with integral washers. Does anyone know the specification of them? cheers. Link to comment Share on other sites More sharing options...
Eriedor Posted April 25, 2022 Share Posted April 25, 2022 JP - This is the grommet I believe, doesn't say dimensions unfortunately - https://caterhamparts.co.uk/fittings/5459-grommet-fuel-hose-through-boot-support-bar.htmlHow much R14 hose did you need in the end? I'm thinking of replacing my hoses with ethanol resistant ones as I've currently got the whole car stripped and fuel tank out already. Also did redline provide E10 resistant bits for fuel filler neck etc? Link to comment Share on other sites More sharing options...
JP Posted April 25, 2022 Author Share Posted April 25, 2022 #27 - thank you that - I'll order a few as I'm bound to trash them.So, I ordered the following from Redline: Fuel tank Hose from tank/pump to filter - new made up hose from redline. New filter New "J" pipe from hose to filter and new adaptors for inlet and outlet of filter New banjo bolt New sender, screws and washers. New fuel pump. New tank to filler neck hose, but this was longer than the original and so for now I've just refitted the old filler neck hose.As for fuel hose I ordered 5/16 R9 hose from VWP for the low pressure return hose and vent. This is the same spec as was already on the car.Also ordered some heater hose for the thinner of the 2 fat pipes from tank to filler.Cobbled it all together and it fired up immediately!I've also discovered that across most of the country Esso 99 is actually E0, not E5, so I'll be using that where I can from now on...reading my owners manual it specifies that the K-series supersport should be 98RON only. I've only had the manual for 20 years and only just noticed that! Link to comment Share on other sites More sharing options...
7 wonders of the world Posted April 26, 2022 Share Posted April 26, 2022 You need R14 hose to be safe with E10 fuel - R9 will start to crackGates Barricade hose is readily available in rolls that2 or 3 members can split, theres plenty in the archives Link to comment Share on other sites More sharing options...
SM25T Posted April 26, 2022 Share Posted April 26, 2022 Heater hose ?? Not in the fuel system ... Even the filler neck. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted April 26, 2022 Member Share Posted April 26, 2022 "You need R14 hose to be safe with E10 fuel - R9 will start to crack"Please can we check this. I thought that SAE J30 R9 was appropriate for E10 fuel in this sort of application.ThanksJonathan Link to comment Share on other sites More sharing options...
JP Posted April 26, 2022 Author Share Posted April 26, 2022 R9 is what was on the car when I dismantled. Link to comment Share on other sites More sharing options...
