Richardfv432 Posted March 3, 2020 Share Posted March 3, 2020 I have just replaced my old FV432 fuel pump next to the collector filter with a reconditioned one, only to find it is leaking/weeping diesel very slightly where the pump is bolted on to the collector filter box; now most of us would think its just the cork gasket leaking.....!!well after three attempts ,I gave up with this idea and placed the pump and box up high so I could see where the slight leak was coming from and when lifting the pump, the 'MOD' date sticker came away from the base of the pump housing. Then to my amazement I saw a small hole not much bigger than a needle size, the hole was hidden behind the sticker. My question, is this hole there for a reason?, it looks like it should be there, only my old pump never had this slight weeping. Is there anyone out there that has the EMER on this pump please, just to put my mind at rest. I believe they are still in use on some of the modern vehicles. The easy way to rectify the leak would be to just use a self tapping screw. Any help would be much appreciated. Richard Quote Link to comment Share on other sites More sharing options...
attleej Posted March 3, 2020 Share Posted March 3, 2020 Richard, Can you be clearer where the leak / hole is? Perhaps a Pic. John Quote Link to comment Share on other sites More sharing options...
Richardfv432 Posted March 3, 2020 Author Share Posted March 3, 2020 Hi John I will get a photo at the weekend, the hole is just in front of the bottom bolt that goes into the collector filter box; its in the black outer casing of the pump, if that helps.

attleej Posted March 4, 2020 Share Posted March 4, 2020 Richard, I don't know what others think but I don't think that it should be leaking from there. I will check some other pumps tomorrow and refresh my memory. John Quote Link to comment Share on other sites More sharing options...

andym Posted March 5, 2020 Share Posted March 5, 2020 I've been trying to find a decent drawing, the only one I've seen is in the ISPL. Judging from that the hole is on the motor side of the shaft seal so it looks like you've got a leaky seal. What's really needed is the EMER for the pump.

Andy Hi Richard, we use a low temp aluminium weld called Durafix when we have to fix housings on this pump see below https://www.youtube.com/watch?v=n1njyuPBIH0 https://www.amazon.co.uk/Durafix-Aluminium-Welding-Easyweld-Brush/dp/B00GG09068 Id suggest the unit has that part of the housing removed and cleaned of any traces of fuel before you attempt any repair Hi Andy,Thank you for looking further into this, Shaun say's this does seem to be a problem and suggests welding,I am going to try this as the pumps works fine, if you do find the EMER drawing that would be fantastic, maybe Clive has it ?.

andym Posted March 6, 2020 Share Posted March 6, 2020 The EMER is EMER Pwr P 424/1 if anyone has a copy. Andy Quote Link to comment Share on other sites More sharing options...
attleej Posted March 6, 2020 Share Posted March 6, 2020 I forgot to look yesterday. I will set my phone alarm to remind me. Blocking the hole is the easy bit if you want to do it. Andy is right and that is my concern. If there is a shaft seal between the pump and the motor, and it is leaking blocking the hole is merely a bodge and will bite you later.

Richardfv432 Posted March 6, 2020 Author Share Posted March 6, 2020 Hi Andy,Clive and John Thank you all so much for your helpful advice and information, I cannot see any hole in the drawing, so it could be an old MOD plate weld hole, who knows. I am going to send the pump back to EICS and I hope to get a replacement without to much fuss. If anyone comes up with anymore information, I would be most grateful. Sheaun at Carwood, Coventry did say, the are often welding these pump casings, so it might be a common fault, only keep your eyes open guys, as the hole was hidden behind the MOD Sticker.

terryb Posted March 6, 2020 Share Posted March 6, 2020 the hole is meant to be there! it is a witness hole and serves two purposes; lets you know when the two oil seals between the pump part and the motor part have failed (diesel will seep out of the hole) stops leaking diesel filling the electric motor which has the potential to start a fire as mentioned on here, stopping a small problem with a bodge may well lead to something much worse.......

Richardfv432 Posted March 6, 2020 Author Share Posted March 6, 2020 Thank you Terry, there had to be a reason why its there. I have only been running the pump for no more than an hour or so, as I have just bought the pump as a reconditioned pump. My old pump had been on for well over ten years with not any problems....

Richardfv432 Posted March 7, 2020 Author Share Posted March 7, 2020 (edited) Thank you Clive. These vehicles are sent to try us!! What would be interesting, is how many people out there have faulty pumps and do not even know it!!.
