Spin on fuel filters

[luvrbus]

If you wonder which is which on the top in fine letters will be primary or secondary markings fwiw

   Forget those fancy wonder filters. They are great, especially for the newer four cycle engines that use more precise injection systems. Just go with primary and secondary spin ons. Low in cost and have been used for millions of Detroits with no issues. I take a permanent magic marker and put date and mileage on each element. You can install a pressure sensor in head of filter wired to a dash light to warn of increasing restriction.

Or install a pressure gauge in top of the secondary filter when it starts reading low change the filters

I change mine every year. It is not like it is a lot of money!

Especially if you get them on sale.   I get mine each winter/spring during the Napa Gold Filter sale.

OT but the best buy on filters takes place when the DD dealers have their spring sale both fuel filters and the oil filter comes in a pack for under 20 bucks I always bought mine from Pacific Power or WW Williams fwiw

Dan,

Your welcome. Glad they arrived in one piece (or 4 pieces).

Ok I'm new here and always learning. My 4106 has the canisters for fuel filters, motor and transmission has spin-on filters. I'm doing a lot things to this bus to update and service. The one thing I haven't done yet is the fuel filters, the main reason, I have read somewhere that you better not lose the prime and opening the fuel filter would cause that to happen. So, how does one change out the filters without losing prime? That is the last thing I want to do. Thanks

   While you are changing over to spin ons, good time to install an inline electric fuel pump. Makes filling filters super easy.

I found a place I can buy the Racor filter with the built in primer for 84 bucks not bad and they work to prime a old DD www.4land4sea.com,spin on filters are a lot easier to prime that the old antique canister type IMO I also think the inline pumps are great

[lvmci]

No kidding, the old cannister are half again heavier, if not more,  the element moves around and its bigger and more awkward to install, thank you Clifford for showing me all that, tom...

[luvrbus]

Lol make a believer out of one Tom when you see the old fuel pressure go from 6 lbs to 40 at idle

Cosmo,

I have one more set of the spin on filter heads, if you'd like to make the upgrade. Same deal as Thekid's: $50 + shipping. As with Thekid, I'll include two new filters.

If you're interested, PM me your zip code and I'll get a shipping quote.

As for losing prime, just fill the filters full, which is much easier with the spin on filters. When you start the engine, manually raise the rpms a little, for 30 seconds or so, and you should be fine.
