I purchased my FPHE(s) from DudaDiesel.com

I may have even gotten them for less than $60 each.

So many to choose from. 16 to 20 plates should be fine for our benz diesels.

Consider getting 1/2"FIP ports for a more compact install. Attach the appropriate 90* fittings given what type of connections you wish to use. barb is simplest as hoses can be attached directly. 5/8" heater hose for the 617 and 3/4" on the 603 and 606 unless a 3/4-5/8-3/4 Tee is used for tapping into the cooling system.

Factory fuel hose sizing is 5/16". bumping up to 3/8" for as much of the VO segments makes it easier when sizing components. Use which ever suits you best.

Pex fittings at your local plumbing supply are a good choice for a compact T fitting. Be sure to measure your hose inlet and match it to the fitting size as the numerical sizes dont match.
