ALEX 98 1 Cars Posted February 12, 2007 My Fuel pump went at the weekend. My second-hand replacement pump is the earlier design, (the black one, more common) I had to chop off the plug form my wiring loom on the car as mine has the newer white pump connector. I cut off the plug from the new pump and was going to use spade connectors to connect it up. That was until the wires from the pump snapped off and were too short for me connect anything to it. It looked like the previous owner had fitted an immobiliser causing them to snap. I dug out the plastic like gel in the recess and found two spade connectors, which I replaced. The pump is now wired in and works fine, but I'm wondering if I should fill the recess in the pump where the connectors plug in. Without buying anything I have in the garage Builders mastic (grey). Window Sealant (brown). Kitchen Silicone (white). Will any of these be OK? Share this post Link to post Share on other sites
hengti 2 Posted February 13, 2007 replaced my fuel pump a couple of weeks ago and noticed that a previous owner must have fiddled with it as the leads had been cut and scotchlok'd for a couple of ordinary crimp on connectors. there was no resin block in there. there was some sort of cream coloured sealant on the terminals though. no idea what it was but it hasn't caused a problem in the 7 years it took me to break the fuel pump i just put some vaseline on the terminals maybe something like waxoyl would be a good idea though - ? anyone know what this cream coloured stuff is? seems to do the job Share this post Link to post Share on other sites
pugrallye 0 Posted February 13, 2007 standard silcone or RTV sealer is fine for filling in gaps in terminals etc and its always a good idea to prevent probs down the line Share this post Link to post Share on other sites
ALEX 98 1 Cars Posted February 13, 2007 I think the sealant is to fill any gaps where the male end of the spade connectors poke through the pump casing. Probably just a precautionary thing to keep fumes away from the connectors. I'll use the mastic, I think it i'll be O.K. Share this post Link to post Share on other sites
