Alternate Fuel Filter

[webdawg1]

Just wondering as to what kind of filters (If any) everyone might be adding in prior to the electric fuel pump on the 75-78 model years. I suppose you could probably do the same thing on the early 240/260 models as well. I ran across an AC Delco unit that will make it quite easy to filter the fuel prior to the fuel pump, as well as changing the filter at regular intervals.

There is no fuel filter prior to the fuel pump on 75-78 cars! That is a fuel damper. But if you were going to use an aftermarket filter on an efi car, in place of the underhood fuel filter, make sure its designed for fuel injection.

Stephen, I think webdawg1 was talking about adding a fuel filter between the gas tank and rear fuel pump, not replacing the existing filter in the engine bay.

Webdawg1, do you have a part number for the filter housing and element? Was there any information on the pressure and/or flow rate losses?

I was thinking more along the lines of "In addition to" and "Not in place of" the fuel filter up front in the engine compartment. I was thinking along the lines of using the fuel feed line out of the fuel tank, (Make a bracket to hang it on) but prior to the electric fuel pump. The little fuel filter in the intake side of the fuel pump is pretty lame at best, and somewhat hard to find if you need to replace it. At least this way it will do a really good job of filtering the fuel, and be easy to replace as needed.

I use a similar boat filter setup in my cars, on the suction side of the pump-the filter is the same package as a Fram PH8A oil filter, but the media appears to be different.

3/8" in and out kept integration simple.

GunnerRob,

About all I have is a url: http://hotrodparts.com/rollsbentleyparts/fuel-filter.htm

I already had the filtering unit, but I was trying to find out which other fuel filters could be used (I.E. - Fram, AC Delco, Napa...etc...etc, as well as the P/N for each), as well as a decent picture showing what it looks like. I was doing a search on the web and found this company that sells the whole thing...appears they are retrofitting RollsBentley's with this newer type filtering unit....looks like quite an improvement over the old filtering unit...four bolts vs. twist on twist off. At any rate tho, I was kind of curious as to what everybody else was doing to address this issue.

Some of the other filters that can be used with this unit would be:

AC Delco: GF-157

Fram: CG20

Napa: 3271

Webdawg1, sblake01 is correct in that the US '75-'78 280Z's don't have a fuel filter prior to the fuel pump that's located back by the fuel tank. The only fuel filter in these Z's are the ones on the passenger side in the engine compartment. It's a big honkin' black cylinder mounted on the front of the wheel well. Any other fuel filter besides that would be added on by a previous owner.

In the picture below, the filter is the round, shiney object on the bottom right side.

My bad. I missed the word 'adding'. There was another member here who recently replaced his fuel damper with a filter. In my experience, however, the little filter in the inlet of the fuel pump is easy to remove and clean and I've never seen one get really dirty even on junkyard cars.

Rob,

webdawg1 is talking about an extra filter between the gas tank and the fuel pump. I don't understand why everybody keeps saying the filter is under the hood- we all know that! If the filter inside the fuel pump isn't fine enough you'll get dirt ( or rust) in your injectors, or if too fine, the pump will get blocked, so on these older cars I think it would be a good idea to put on that rextra filter. Especially if it's easy to change out. The filter under the hood is easy to change, but takes time with all the clamps, & hoses. If there was a twist-on filter mounted by the gas tank, you could conceiveably change it in a minute.

thx

There is a small cone shaped filter in the inlet nipple of the fuel pump on all of the EFI cars-it is hell to get out without destroying it, but it can be done. I will see about posting a picture of one tomorrow-we discussed this gem in at least one other thread sometime inthe last year and a half-but I don't remember exactly where.

Steven mention a screw-on filter like an oil filter. That would be nice.

The only problem is that if you don't change the filter quick or plug the line(s), you'll get some gas flowing out of the hose.

Sorry Stephen, I missed your post-I have almost always had a heluva time getting that little filter out-of course that is from parts cars with varnish in the lines...
