What size sockets for fuel filters?

[fonecop1]

What size sockets do I need to change my fuel filters?
Thx,
Bob

35mm for HFCM
24mm for the secondary filter (or 15/16)

Lisle makes a short profile 35 mm socket for about $8 - sells at most autoparts stores

The fuel filter cap down on the frame rail uses the same size socket as the oil filter cap... 36mm
The one up top is 24mm or a 1/2" extension will also work

I crawled under it lastnight and a 35 MM fit the fuel filter cap but it won't fit my oil filter cap, I guess that one is a 36MM. Thanks Guys

That is strange. The filter cup on the frame rail and oil filter cap should use the same socket. Has your oil filter cap been changed to an aftermarket one??!?

Thats because they're 36 mm. They're the same exact cap.

+1 for the 36mm socket. I use it for both. The 2nd fuel filter is 15/16". Do NOT use the 1/2" drive socket to open the 2nd one, or you will probably break the cap. I broke mine this way, as did about 3 other people I know.

I bought a really nice chrome vanadium 36mm low profile socket new on e-bay for $7.99 plus shipping

an 1-3/8" socket will also work

I don't know but my 35 MM axle socket fit the lower fuel filter and doesn't fit the oil filter, I expected them to be the same.
