Pig Posted August 15, 2007 Share Posted August 15, 2007 Just thought i would put a pic up as i have now re-wired due to bare wire at the connection. Could this potentially be dangerous? Work completed by turbofit. Sorry about the bad pic, for some stupid reason i deleted the close up ones. Link to comment Share on other sites More sharing options...
Guest gzaerojon Posted August 15, 2007 Share Posted August 15, 2007 i can never get my head round the thought of bare wires submerged in fuel but the walbro kit comes with 2 crimp terminals that are essentially bare wire submerged in fuel, plus the connector is not sealed off either. but it's aparently normal Link to comment Share on other sites More sharing options...
mattanna Posted August 15, 2007 Share Posted August 15, 2007 when taking senders out you can often see the odd bare bit showing, it would only be an issue if they connected with something, i.e a live terminal or something so i believe Link to comment Share on other sites More sharing options...
RobSheffield Posted August 15, 2007 Share Posted August 15, 2007 Whats wrapped around the Walbros?! The Walbros come with a special sleave..... Link to comment Share on other sites More sharing options...

b_have Posted August 15, 2007 Share Posted August 15, 2007 Whats wrapped around the Walbros?! The Walbros come with a special sleave..... The sleeves act as a screen. Apparently quite important when running two in close proximity. Oh, and normal cable ties can dissolve in fuel. Link to comment Share on other sites More sharing options...
Muffleman Posted August 15, 2007 Share Posted August 15, 2007 What is the right way to attach a second pump to the hanger ? Or can you buy twin pump hangers ? I know MVP do a triple hanger, so is it best to get a triple and leave one empty ? Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted August 15, 2007 Share Posted August 15, 2007 The time to worry is when you have a + wire bare that might come into contact with earth:bang: And i would definitely use the sleeves, helps cut down transmitted noise, also it wouldn't have taken five minuets to make a carrier that kept the pumps separate.

SimonB Posted August 15, 2007 Share Posted August 15, 2007 The screen doesn't come with the pumps - it's part of the PHR fuel kits (and some others) or you can buy it separately. The triple hangers are pretty expensive, I wouldn't bother. When I fitted mine I chopped the bottom off the hanger and made a bracket out of aluminium with two holes for the rubber isolators that the pumps sit on - then I bolted that to the hanger. Otherwise the second pump isn't held at the bottom by anything, so could slip. I'd be more worried about the fact that there's 2 pumps going to the single stock power and ground lines in the connector which aren't really up to it. What most people do is change the ground connector to a second power line and put a separate ground connector in (i.e. ground the pumps to the hanger and a ground post on the top of the cover).

SimonB Posted August 15, 2007 Share Posted August 15, 2007 also it wouldn't have taken five minuets to make a carrier that kept the pumps separate. It's actually quite hard to do that as there's not much room in the surge pot in the bottom of the tank. Link to comment Share on other sites More sharing options...
Homer Posted August 15, 2007 Share Posted August 15, 2007 Shocking, just shocking One bare wire is okay, but it's obviously best to cover them. The postive and negative connectors should also be staggered, just in case the insulation fails (unlikely). Also, it looks like both pumps have been wired into a single feed, they should be seperate on on their own relays. Also as mentioned, one pump needs to be wrapped if you have a dual pump system Cable ties - wtf! Anyone thats used TF to install dual pumps needs to get theirs checked now Link to comment Share on other sites More sharing options...
Terminator Posted August 15, 2007 Share Posted August 15, 2007 You can get pumps three in the pot. Get rid of those horrid fasteners use a big clip. PHR do a magnetic shield to go round one of the pumps. Petrol is not that flammable. I don't recommend trying it but I have seen a glowing fag butt extinguished when it was thrown in a container full of petrol as demonstration. vapor is a different matter.

Pig Posted August 15, 2007 Author Share Posted August 15, 2007 more money needed to put there work right P.S I bought the PHR fuel kit so should have had a sleeve. Dread to think why it wasnt fitted Link to comment Share on other sites More sharing options...
Wez Posted August 15, 2007 Share Posted August 15, 2007 When I got my pump from FuelSystems in the UK it came with a sleeve Link to comment Share on other sites More sharing options...
JustGav Posted August 15, 2007 Share Posted August 15, 2007 On a different note, shouldn't dual pump systems have twin feeds all the way down through 2 fuel filters to the fuel rail? Link to comment Share on other sites More sharing options...
Wez Posted August 15, 2007 Share Posted August 15, 2007 On a different note, shouldn't dual pump systems have twin feeds all the way down through 2 fuel filters to the fuel rail? Why? Its fine to have a Y in the tank and then another the other end if you want dual feed. Link to comment Share on other sites More sharing options...
JustGav Posted August 15, 2007 Share Posted August 15, 2007 Why? Its fine to have a Y in the tank and then another the other end if you want dual feed. More of a curosity thing, surely the factory line would be the correct diameter for a single pump, and adding a 2nd pump wouldn't be able to take full advantage of a single line unless the single line had a suitable increase diameter wise. Also, the dual pumps systems are meant to be matched to a duel entry feed fuel rail aren't they? Link to comment Share on other sites More sharing options...

Also, the dual pumps systems are meant to be matched to a duel entry feed fuel rail aren't they? That would be the case on a very high power car, but Jon's only running a small turbo. Provided the feed from the hanger to the filter is of a suffciently large size (-8 is plenty), it doesn't matter if it runs a dual or single line to the filter. The really high power cars run a dual filter setup to dual feed on the rail, but on Jon's power level that would be complete overkill. At 1.4 bar my T67 runs just fine on a single pump, stock lines, stock filter, stock rail and single feed. There's no sign of pressure drop.
