digs Posted July 10, 2013 Report Share Posted July 10, 2013 (edited) Hi Just having a quick panic. I fitted a new 255 fuel pump to my st202 (for turbo). I had to cut the wires of the old fuel pump, and used a crimped butt terminal, e.g. http://www.thetoolboxshop.com/0-001-16-pack-of-50-durite-coloured-crimp-terminal-butt-connector-yellow-6131.html , to connect the now exposed wires from the old pump to the connector on the new pump. So...before I switch on....having an attack of nerves. Assumedly, this is fine and will not do anything stupid like ignite the fuel ? I can't see why as there are various connectors and wires in there, and fuel pumps burn out without igniting, but wanted to double check before starting her up. Thanks for any comments. EDIT - link doesn't work! should this be sealed somehow ? Edited July 10, 2013 by digs Link to comment Share on other sites More sharing options...
carlasumm Posted July 10, 2013 Report Share Posted July 10, 2013 your link isnt working but i would say as long as you have insulated everything properly it should be fine Link to comment Share on other sites More sharing options...

carlasumm Posted July 10, 2013 Report Share Posted July 10, 2013 (edited) make sure you stick electrical tape over the top as well personally that sort of thing i would have solderd the wires together and heat shrinked them individually then one larger one over the top to turn it back into a type of loom http://www.ebay.co.uk/itm/127-pce-Assortment-Black-Heat-Shrink-Wrap-Sleeves-Tubing-Sleeving-Wire-Cable-/170896951473?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item27ca4088b1 Edited July 10, 2013 by carlasumm Link to comment Share on other sites More sharing options...
digs Posted July 10, 2013 Author Report Share Posted July 10, 2013 It's not too late for a trip to maplins to grab some heat shrink I think, rather be safe then....errr.....well a touch crispy Dublet, the power of my faith will defend me from the flames, don't you worry Link to comment Share on other sites More sharing options...

princy Posted July 10, 2013 Report Share Posted July 10, 2013 As Carla says I'd have covered the connector with heat shrink Link to comment Share on other sites More sharing options...
digs Posted July 10, 2013 Author Report Share Posted July 10, 2013 As Carla says I'd have covered the connector with heat shrink Thanks, decided to, off to see if maplins has some. Rather spend a bit longer on it than not Link to comment Share on other sites More sharing options...

carlasumm Posted July 10, 2013 Report Share Posted July 10, 2013 better off doing it the once and doing it properly rather than having to to redo it later Link to comment Share on other sites More sharing options...

martinking6 Posted July 10, 2013 Report Share Posted July 10, 2013 The heat wrap doesnt last long unless you buy the expensive oil/petrol resistant stuff and same goes for your insulated terminals you posted a link to, I use a commercial heat shrink connector thats resistant or where I can I will run new wire with terminals either side so no connectors Martin Link to comment Share on other sites More sharing options...
carlasumm Posted July 10, 2013 Report Share Posted July 10, 2013 if im right hes connecting the wires out side of the tank so no petrol or oil should get anywhere near the joins at all as they would be inside the car and well away form any fluids of that sort Link to comment Share on other sites More sharing options...
martinking6 Posted July 10, 2013 Report Share Posted July 10, 2013 Good stuff :-) Martin Link to comment Share on other sites More sharing options...
digs Posted July 11, 2013 Author Report Share Posted July 11, 2013 Nope, it's inside the tank, connects the new fuel pump wiring to old one, so will need to be resistant. Balls! I guess then its pull out and replace with resistive wrap... Least I know how to do it Link to comment Share on other sites More sharing options...
Limeymk1 Posted July 11, 2013 Report Share Posted July 11, 2013 I try to use at least 2 layers of heatshrink on my wires as it makes it almost as thick as the original insulation. Link to comment Share on other sites More sharing options...
_Chris_ Posted July 11, 2013 Report Share Posted July 11, 2013 As above, it will be immersed in petrol so will need to be petrol resistant. IMO use a piece of petrol hose as insulation, and make it long enough that if it drops all the way down the wire, the joint will still be covered - i.e. make the wire above the joint longer than below and put the tubing above while making the joint. DONT use sticky tape, the stick won't last 2 minutes. Don't rely on cable ties unless you use petrol resistant or stainless ones (the latter WILL conduct of course) Don't mount the wire in such a way that it can rub on any metalic surface and wear away the insulation.
