2 fuel filters on 04 400 ISL TS04

[rhusak]

Hi All..
Do you know if my 04 ISL 400 has 2 fuel filters? If so is one hidden up along the block somewhere? I have taken a cursory look but have been unable to find a second!
Thanks in advance for your help..

We have the ISL370 in our MH and it had (1) combo fuel/water separator filter. Some manufacturers went from having (2) filters to (1) in the early to mid 2000's supposedly to save $. We had a Cummins-Onan shop add a second one back to ours two years ago.

we had the ISL400 in our 2004 MADP.....and it had only 1 fuel filter...what a PITA it was...with the fourth (4) lift pump I had a seconf=d filter installed between the tank and the lift pump,,,,what a difference that made...Chuck

Ron, in 04 there were a number of coach's from different builders with only one filter. My chassis was built May 05 and has two.
