Sutty2006 Posted April 13, 2013 Share Posted April 13, 2013 In the process of fitting an injected c20xe into my carb'd manta, the injection tank I have is fubar. What ways are there I can modify what I already have? Getting another tank might be hard. Putting a return hole into my existing tank seams more work than I want to undertake.... (drilling, tapping etc) I need to have the job done right. Ive been told some people feed the large breather pipe on the filler neck with the return pipe.... doesnt quite wash... What should I do?!

rutts Posted April 13, 2013 Share Posted April 13, 2013 use a swirl pot in boot feed return to that. Quote Link to comment Share on other sites More sharing options...
®evo03 Posted April 13, 2013 Share Posted April 13, 2013 (edited) just converted a 1.8 manta to redtop last year! still running original tank and wiring loom. So, the tank, put your petrol pump (standard GTE or Redtop setup setup, in the boot, (keep it dry & warm!) (I've fitted mine behind interior panel right and side, yes, the space in the quarter panel. rubber mounted, coplete with filter, and pressure control. Your return feed works by T'ing into rubber over flow pipe. from the filler neck to the top of your tank. you will need a selection of different petrol hose, standard zinc petrol pipe, ( Expensive.) and a PTE plastic T's and reducers. (I wish i took photos!_ Didnt use swirl pot, never had any problems, it ran with a completely empty tank. only 5 litres of petrol added. Just flow the petrol lines up your car, like a GTE, (this was the hardest job, but do-able!!) Your wiring, its easier to wire a 2.0 GTE to redtop loom. you can use a 1.8 loom, ive done it. Just a live feed wire to your pump is needed. earth the pump, fuse the live feed. Hope this helps, these cars can be converted as standard 1.8 stuff, on a low budget. no problem...............

mantadoc Posted April 13, 2013 Share Posted April 13, 2013 use a swirl pot in boot feed return to that. You can but it's not best practice as it leads to the same fuel being recirculated and picking up heat from the engine bay, plus the swirl pot should be able to overflow into the tank so you should have a return for that as the HVLP lift pump needs to be able to overfill the swirl pot and outsrip the HP pump If it's going to be a serious car a swirl pot is always a good idea stop it sucking air and holing a piston Quote Link to comment Share on other sites More sharing options...
Sutty2006 Posted April 14, 2013 Author Share Posted April 14, 2013 It's just a standard c20xe, no modifications that I know of internally. I've looked at swirl pots on the bay and yes they too need a return to the fuel tank. I might end up drilling a hole in the sender unit, I just don't want it to leak!

Shug Posted April 14, 2013 Share Posted April 14, 2013 When I put injection on my 2.2 a series, I drilled a hole in sender, chemical metal to hold pipe in place, and liberal coating of tank seal. Seems to have done the job. Quote Link to comment Share on other sites More sharing options...
611 Posted April 14, 2013 Share Posted April 14, 2013 You can also get these. http://www.ebay.co.uk/itm/AN-6-6AN-Fuel-Cell-Tank-Adapter-Bulkhead-Fitting-Black-/170683223497?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item27bd834dc9 and as Shug says have an extra hole drilled for the inlet in the tank sender plate. Better option than the return into the filler neck. Andy Quote Link to comment Share on other sites More sharing options...
