How To Test Diesel Fuel Filter

Will an auxiliary fuel filter crusade catamenia or restriction issues with my vehicle?

We make both primary & secondary filter kit options for almost popular diesel powered vehicles utilizing common track fuel systems. Both versions of auxiliary filter give effective protection against premature fuel arrangement component impairment caused by contamination. We recommend the secondary as being the best option though. This is because the finer micron filter used in the secondary kit (usually 2 micron as compared to xxx micron used in the master kit) means the fuel entering your loftier force per unit area fuel system contains less annoying particulate matter; then information technology'south as clean as it tin be.

Nosotros are regularly asked questions relating to catamenia restriction or performance loss if an auxiliary filter is fitted. We believe these fears could be because if an inadequate type of filter is used, problems such as power loss or surging could occur. Nosotros besides think information technology'south because there is a lot of misinformation out there from a variety of sources which simply has no ground of credibility. Nosotros regularly hear these claims & we can say with confidence that the vast majority are made without foundation or evidence. If a suitable filter with adequate fuel flow capacity is used there is no problem with installing an auxiliary filter, in fact it is the single best matter yous can practise to prolong the life of any diesel injection system. The Fuel Manager filter we use in Diesel Care kits causes no problems with fuel supply or flow; in fact they nowadays very fiddling restriction. If there was any trouble at all nosotros wouldn't use them.

Recently we produced the film clip above and bachelor on Y'all Tube for all to see. Nosotros wanted to dispel the myth which constantly raises its caput relating to secondary filtration causing flow issues, and then nosotros ran a Toyota Hilux on our Dyno over a series of ramp runs & measured:
i) engine output at the wheels
2) fuel supply vacuum
3) fuel return flow.

Firstly we recorded readings with the manufacturing plant filter merely connected, then again with a 2 micron secondary filter added. At that place was no modify to power or return fuel catamenia, & simply a minor increment in vacuum of about -0.v psi (i"Hg). To emphasise a point we connected all the same another 2 micron filter in series, so at present we had 3 filters in the system. Once over again at that place was no alter in power or return menstruum, & similar increase in vacuum as the beginning filter had. We concluded that a 2 micron Fuel Manager filter will present a brake of less than –0.5 psi (i"Hg) and does not alter fuel menses or engine output. Equally a matter of interest the high pressure level pump on a Hilux is capable of pulling a -ix psi (18"Hg) vacuum, the maximum vacuum we measured in our test with iii filters in place was -iv.4psi (8.5"Hg).

It should be understood that any filter will present more than brake every bit it becomes progressively muddied; this is because it is doing its task. We recommend that fuel filters are changed regularly. In the example of the vehicle mill installed filter; information technology should be replaced equally often as the manufacturer recommends at the very to the lowest degree, & in the instance of a Diesel Intendance auxiliary filter; twenty,000kms for a master filter & 40,000kms for a secondary filter.

We encourage you to watch our You Tube clip & run across for yourself that adding a suitable auxiliary fuel filter causes none of the problems that the "forum experts" or "anti aftermarket doomsayers" claim. The show is in the testing nosotros've done & the thousands of secondary kits we've supplied or fitted across Australia to around 40 different makes & models. We've saved hundreds (if non thousands) of fuel systems from an early death due to fuel contagion, & opposite to a few of the forum skillful's claims; we've acquired harm to none.

We hope this information helps yous brand a conclusion.
