Relocating fuel filter to engine bay - drawbacks?
Would there be any drawbacks in relocating the fuel filter to the engine bay for the SPI/Zetec models? Without spending too much time on other than how, it appears it could easily be done.

Why? - saving time under the car with that ~7/16" screw.

How? Using an old filter, cut off the metal inlet and outlet tubes. Flare the ends just enough to hold rubber fuel injection hose then clamp on enough rubber fuel injection hose to span the gap between existing connections where the filter used to be located under the car.

Mount the filter in its new location just prior to the fuel pressure dampener in the existing rubber fuel injection hose. Determine a method to secure the filter.

Is there a reason as to why the filter is closer to the tank instead of in the engine bay? Fire danger? Surely some cars have mounted a fuel injection filter under the hood.

All that time you'd save would be wasted in putting it under the hood. It really doesn't take that long nor is that hard to do. I don't see the why being enough to justify the work IMO, but surly it could be done.

I'm thinking it could be done in less than an hour. True - at this late stage in the cars life the benefit of time/# of changes has decreased.

Anyone carry a liquid/gas fire extinguisher in their car? - lol.

It can be done in less than 30min with it under the car, just a pita to get up under there. I totally understand the fire extinguisher lol

No reason not to put it under the hood, it's done that way on MANY vehicles....

In theory, if you get a REAL bad load of crud in the tank, and need to clean the line from the tank to the filter, it's easier with the filter located in or near the tank.

This being an uncommon occurrence, and filters NOT being changed as needed due to the difficult access (out of sight, out of mind) - the engine compartment location makes more sense for most folks.....

My old Mitsubishi Mirage (91') had it under the hood and was easy to get to. Went to change our Honda Oddy's and go to look under the hood only to find it not there. No biggie then went on to find it's none serviceable and is in the gas tank itself. [facepalm]

I don't like how manufacturers are going to non-serviceable items like the tranny fluid and fuel filters now a days. Chevy's new 6 speed auto has no drain hole or fill hole. It's got what they call lifetime fluid, or what I would call, last till the warranty goes out fluid. Surely some of us remember fords lifetime air filters they put on the early duratecs. Remember how well that went lol

Cadillacs, BMW'S, all with "lifetime" automatic transmissions.....


Yeah, just install a new one......

Moved to SPI Performance.

GO for it if you want to, and do a How-To in case anyone else is interested. Your problem might be that, at least on my car, it's a 5/16 or 8mm screw. It would be difficult to loosen with a 7/16 or 11mm.
