Hello. I have a question please.
I've searched through the forums, but have not found anything about my specific question. If I missed something, please be kind - this is my first post even though this website and you all have been invaluable when I was looking for my NSX (I've already joined NSXCA)!
OK - I decided to replace the fuel filter on my '92 NSX with ~65k miles. The 60k service was completed by the previous owner at an Acura delaership and they listed "fuel filter replacement" in the work order. However, an examination of the parts list on the receipt did not turn up a fuel filter. It didn't look new, so I just bought another one from my local Acura dealer.
What a pain to change it. Some of the threads here were helpful about suggesting to remove the engine cooling fan, but I was just able to avoid that. I was thinking it would take me 1/2 hour like a regular car, but this turned into almost 2 hours.
My problem arose when I went to install the banjo bolt on the outlet of the new filter that goes to the engine (with the new washers of course). I couldn't get the bolt to align exactly with the fuel hose connection such that it is a straight shot into the hose. It's about 1 or 2 degrees off-center. In this configuration, the fuel pressure is fine, but I may have reduced the flow rate of the fuel slightly.
I was able to get the inlet fuel hose to the fuel filter perfect and torqued to the recommended 28 ft-lbs. I think the outlet is torqued to about 40 ft-lbs trying to get it lined up. It's interesting to note that getting off the inlet to the old filter was difficult because the (factory?) had it torqued down to about 40 ft-lbs to get it lined up correctly.
I don't think I can torque it any more without doing some damage to the filter or rounding off the head. It's only off by a few degrees and the outlet of the banjo bolt and the inlet of the fuel line are both countersunk so they are somewhat flared (which helps the fuel flow).
I haven't had any codes thrown yet about being too lean and it drives fine. Someday I would like to get it dyno'd.
Should I take it back apart and get some thinner washers? Has anybody else encountered this?
Thank you,
Dave
