Now most of us Cruiser heads are guilty of some pretty good hacked PO (Previous Owner) work from time to time. If your truck is like mine was it's full of them! Well the PO had replaced the OEM metal can fuel filter with a cheap plastic one seen in Fig. 1. It worked and you could see that it was working. Since I liked the idea of being able to see the fuel in the filter, I bought an early OEM glass filter from E-Bay. See Fig. 2.  The filter element is still available for it and I liked the 'old school' look of it.  However right about the time I started to clean it up I had a problem with my Sea Ray 175XL boat engine sputtering and cutting out. What does a boat have to do with a glass fuel filter? Well my boat is equipped with a marine water/fuel separator filter as shown in Fig. 3.  When I removed this filter from the boat it had water and lots of dirt in it. This convinced me to adapt one to the Cruiser in place of (or possibly in concert with) the glass filter!

Again E-Bay came to the rescue in that I was able to buy a filter AND the spin on mounting bracket for $12! It is made of aluminum and has two 1/4" NPT input ports and two 1/4" NPT output ports so can be used in a variety of configurations.  I used the OEM filter bracket, and drilled and tapped two new holes to attach the new filter mount. See Fig. 4. A good coat of powder on both to spruce up the old F engine bay and we were ready to go! Fig. 5 shows the mounted filter and bracket. I had to get a couple of 1/4" NPT to 1/8-28 BSPT adapters to make the filter work with the OEM fittings. Fig. 6 shows the completed lines and stuff. Go to the link below for more details on the lines and adapters. The next page has a lot more information about connecting this filter using OEM lines and fittings.
