sierrafery Posted December 23, 2015 Share Posted December 23, 2015 Hi all, i need some help to help a friend, it's about a 2005 Td4 with the suplimentary pump behind the rear wheelarch, according to microcat only the WQB000020 pump would fit which is friggin expensive, anyone tried to fit a cheaper WFX500070 or WFX000200 instead? or at least can anyone enlight me what's the difference between them, the electric connector or what? , i'm confused Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted December 23, 2015 Share Posted December 23, 2015 A late FL1 only has 1 low side pump - the one under the arch; http://www.island-4x4.co.uk/fuel-pump-tdv6-rear-wheelarch-wfx000181-lr023043-lr022382-wfx000180g-p-2543.html The WQB000020 part # is just a pickup and sender. http://www.island-4x4.co.uk/fuel-tank-sender-unit-genuine-0306-wqb000020-p-4899.html Quote Link to comment Share on other sites More sharing options...
sierrafery Posted December 23, 2015 Author Share Posted December 23, 2015 much obliged for the answer, so that ''thing'' in the tank is just a gauge sender and a pick-up unit for the main pump without any activity? it has no motor in it?

Correct,it was only up to 2002.5 that the FL1 had 2 low side pumps - one in the tank and one under the bonnet. from 2002.5 on it was the single pump under the arch.Sensible money replaces the filter next to it at the same time.

sierrafery Posted December 23, 2015 Author Share Posted December 23, 2015 Thanks again, it's a shame how expensive that in tank sender can be while it's just an empty ''shell'' with a float , also some sellers are naming it ''pump'' which made me think it has some motor in it Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted December 23, 2015 Share Posted December 23, 2015 If you google the part number and look at the photo's you can clearly see that the socket only has 2 pins in it. I don't understand why a pickup and sender unit should be so expensive ? Quote Link to comment Share on other sites More sharing options...
sierrafery Posted December 23, 2015 Author Share Posted December 23, 2015 yes, i observed that, do you think that it fits into the tank like the "real" pumps like WFX500070 cos it seems the same shape... my friend has erratic gauge movements too beside the low pressure so i thought to fit one of those older modell pumps instead of that expensive sh*t, get a plug from a scrapyard and give feed to it too...do you think it would work together with the WFX000181, cos that one looks like the secondary pumps on older modells? ...it's a real mess anyway Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted December 24, 2015 Share Posted December 24, 2015 Could do, but be careful to take the old pump out of the circuit,the older pre 2002.5 cars wouldnt run if one of the two pumps failed.Might just be easier to fit the right bits...
