When I went to prime the fuel system, it leaked at the connection between the fuel pump and the stock nylon lines.
Some members have swapped the nylon lines out for something else.
I tried this and broke the nipple/barb molded to the fuel pump hat.
Later I discovered an additional fault on the return line housing. This was probably created during the drilling process. I did not use a drill bit designed for plastic. They exist
Design rev 1
Use 1/4NPT to barb and clamp rubber hose to that.
I ran my rev 1 idea by some smart people with the idea of using a nylon fitting. It was suggested that I may want to allow for less stress/strain on the plastic of the fuel pump. This led to design rev 2.
Note: I eyeballed a tap against the FP hat. The plastic on the FP hat does not have anywhere near enough material to support a 1/4 NPT tap.
Design rev 2
Playing around in the garage, I noticed that there was enough material to drill out to 3/8".
Looking at the DF-supplied fitting that mates to the fuel filter, I realized metal SAE push-on 5/16" and 3/8" flared tube is this diameter.
What if we drilled out these FP hats to accept metal tube?
Materials
3/8" Fuel Injection Hose Clamps FI8
Dorman 800-082 Fuel Line Fitting
Dorman 800-155 Double Bead Fuel Line
Installed metal line
Fuel line assembly
Standard stuff, making hoses. I tried WD-40 and silicone (tire wet). Both worked rather well.
3/8" FI fittings work well. They are different from worm clamps.
Measure your lines before cutting. You may not want them the same length.
Routing & placement
The zip-ties aren't permanent ...or are they?
