wkdtime Posted December 12, 2006 Share Posted December 12, 2006 I recently installed a Walbro fuel pump, supplied by MKIVStore. The pump came with it's own connector lead with a positive and negative terminal. When i took out the old pump i snipped the lead off as i needed to use the top connector as i planned to use this and mate the two terminals to the Walbro connector terminals. I then Soldered the wires together and made sure that the positive was snipped lower than the negative as to prevent the risk of short circuiting. I could not use Wiring Tape for obvious reasons due to the petrol vapour and left it be. I have been driving the car like this and its been fine. Please find a diagram attached to show what i mean. I'm totally paranoid that there will be a spark as the wires are bare at the point were they are joined and it's good bye supra and good bye my ass.

JamieP Posted December 12, 2006 Share Posted December 12, 2006 What about using some heat shrink tube over the wires? Quote Link to comment Share on other sites More sharing options...
wkdtime Posted December 12, 2006 Author Share Posted December 12, 2006 What about using some heat shrink tube over the wires? Where can i get that from? Do i need some sort of heat gun with it? Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted December 12, 2006 Share Posted December 12, 2006 Errr well, whilst they are 'hopefully' far enough apart to not touch, it's seriously bad practice. Best case scenario is that they may make a fuse blow. Worst case... Even if you have to get a small peice of rubber tubing, wrap it around the terminals and cable tie both ends, that would be better. Some nice heatshrink, or heatshrink crimps would be better though. Quote Link to comment Share on other sites More sharing options...
supragold Posted December 12, 2006 Share Posted December 12, 2006 Fancy doing that. If it was me I'd do as Jamie suggested. Quote Link to comment Share on other sites More sharing options...
Homer Posted December 12, 2006 Share Posted December 12, 2006 So you basically have two bare wires in the fuel tank, though spaced apart? It *should* be okay, but hardly safe!!!! You should be able to get some decent shrink wrap from your local electronics store (i.e. maplins), it's only a 20 minutes job, but worth doing for obvious reasons!

D8MOA Posted December 12, 2006 Share Posted December 12, 2006 halfords,maplin,any good motor factors! you only need a lighter to shrink it Quote Link to comment Share on other sites More sharing options...

Graham S Posted December 12, 2006 Share Posted December 12, 2006 I think you'll be ok as long as you have a full tank constantly, wouldn't wanna be running that with a empty tank, like Jamie said, heatshrink, or how about some thin fuel pipe from halfords or any motorist centre and feed the wire inside each one if you know what i mean??

D8MOA Posted December 12, 2006 Share Posted December 12, 2006 when u put the wrap over the bare wire you just put a naked flame under it to heat it and shrink it Quote Link to comment Share on other sites More sharing options...

merckx Posted December 12, 2006 Share Posted December 12, 2006 A hot air gun or a powerful hairdryer. Quote Link to comment Share on other sites More sharing options...
Mike M Posted December 12, 2006 Share Posted December 12, 2006 I used the halfords heatshrink bullit connectors. PITA having to do the job twice to mate. That ring is crap at going back on. Quote Link to comment Share on other sites More sharing options...
merckx Posted December 12, 2006 Share Posted December 12, 2006 This heat shrink is better, much thicker wall. http://www.maplin.co.uk/Module.aspx?ModuleNo=308&&source=14&doy=12m12 Quote Link to comment Share on other sites More sharing options...

Pabs Posted December 12, 2006 Share Posted December 12, 2006 just a thought, but I have, in the passed, used the side of the soldering iron tip to shrink the heatshrink material. NOT the tip, as this is much hotter and just melts it, but the side of the tip shrinks it nicely. EDIT: Electric soldering iron... Only if you haven't got a hairdryer to hand though - as it seems to do a much better job. Quote Link to comment Share on other sites More sharing options...

Ideally you'll have a gas soldering iron to melt heat shrink, failing that using the side tip of an electric one is your next best option. I would never used a lighter for this!

I would never used a lighter for this! good point - didnt think about the gas soldering irons - i'm always the t*t who runs a mains cable from his front door all the way along the path and down the drive to where the car is located, usually in bad weather too (neighbours think i'm mad) - a gas powered iron would be soo much easier Quote Link to comment Share on other sites More sharing options...
