1991 grand villa

November 29, 2015, 11:14:01 am

So I spent a few hours with my new coach on Friday getting ready to try and get it running.It was about 5 degrees and windy so not a pleasant time. I could only find a Raccor 500ma fuel filter/water separator. I did not find a separate pusher fuel pump. I could not see another fuel filter else where on the coach.
So my questions are is there or should there be another fuel filter on or near the motor ? Looking at 3208 motor pictures it seems like they might be mounted on the front of the motor maybe beside the fan on the passenger side and hard to see.
If it was a cat part that would be a likely place. If so what would the fuel filter # be ?
Does the 3208 cat motor in this coach have manual primer pump ? if so I want to replace it as part of my preparation to start. We could not find it or see it during our inspection. Again looking at pictures of 3208t motors it appears there might be the manual primer pump and again location near the front in a similar location to the cat fuel filter.

On a positive note I did find the hour meter for the motor and it was 1800 hours.
Thanks in advance for your answers and hope everyone had blessed Thanksgiving !

That is where the filter and priming pump were located in one of my cranes. If the bed lifts up it would be easy to change.

Will she not start? Yes, those are low hours, we have 4000 on ours. In the temp you describe, the block heater should be fired up. More info, please. M

If the engine is the same as I had there is a glass water separator mounted on the engine. It had rubber seals on the back and when cracked would pull air. Since my engine was in a crane it was factory from cat.

John, On my 89 GV 3208 Cat it had a secondary fuel filter curbside ahead of the two oil filters mounted on the engine. Accessible from under the bed. Also primary Racor filter curbside on the frame behind the drivers....This is where the manual primer pump was located. Yours may be configured differently though.

When you find the manual primer pump which is mounted on the secondary fuel filter:

Unscrew (counter-clockwise) the knural handle.

Pump in and out. If it moves easily, there is AIR in the system. When all the air is out, it will go from easy to VERY head (fuel is non-compressible).

Push the handle in all the way and screw it in (clockwise). This last part is important, as not securing will cause a serious fuel leak.

How true, not to mention (on the Isuzu) the engine would stall.

A common stalling problem on the cat 3208 engines with some age, throttle shaft seal sucking air. Fairly simple to replace. I had 3 cat engines stall on the motorcades.

So to answer some questions asked. No I did not try to start the coach. I was just doing an assessment in preparation to go back and get it started.
My plan is as stated in a previous topic: 1. put on a push electric motor right near the fuel tank .2. Replace short fuel lines near the motor (They have a history of collapse on the inside while looking fine on the outside).3. fix the Raccor fuel/water separator so it does not leak. 4. if it has a manual primer pump on the motor replace that ( they have a history of leaking )5. Replace fuel filters even if they appear ok. 6 put in a site glass in fuel line where it enters the motor ( so that I can see air bubbles ) 7. take the fuel shut off solenoid off and take it out of the equation of does it work. 8. use the fuel pump installed to find and repair any fuel leaks that will show once the pump is turned on.

I will be having the repair shop plug in the block heater 24 hours prior to my arrival so that the motor is as warm as possible.

I plan to attempt to eliminate as many variables as I can prior to attempting to start. I do not plan to be able to fix the leak in a fuel shut off rod and if that is the case I will not be paying the extra bonus on the coach.
So is anyone sure that there is always a manual primer pump and a second cat fuel filter something I have just not seen ?

It will have a spin on filter on the block. It uses a CAT 1r-0750, and if there is room below, can be swapped to the 1r-0749, which is identical, but twice as long.

If your Raycor fuel water separator is leaking that's your problem. The plastic valve on the bottom usually starts seeping or letting air in .I had the same thing happen on my peterbilt. It is in the supply, suction line to the fuel pump ,if it's leaking either bypass it or fix it but that POS will be the problem. I took off all spin on filters and the raycor and replaced everything with a DAVCO 382 setup 1 filter to deal with and it has a drain on the bottom for any water. No issues in 7 years.

So does anyone have pictures of the Cat Fuel filter or the manual prime pump area ?
I am very much a visual leaner so pictures help me understand things better !
Thanks

We are the same; we like pics on this forum. A pic or two of your coach, as well as info
below on your sig is always a help in trouble-shooting.

@stump Would love to see some pics of your DAVCO setup. Where and how it's mounted. I'm thinking this would be a nice upgrade. Don't mean to hijack the thread...

see ya

What Ken said; I'd like to know about the DAVCO, as well. BTW, Threads are made to be hijacked if there is information to be shared: it bothers the mods, but not me. On my irrigation forum, we've gone from "how to repair this" to"Mike Leary's days in the recording studios". Mods leave us alone as long as it does not get nasty, in which case we police ourselves.

Dave Larson
Is that located on the front of the motor on the radiator side ?
I could not see mine on Saturday when I was looking and when i go back this time I want to be fully prepared for getting it running !
I cannot believe how anxious I am to get this thing running and home even if it means I have to sleep in it because my wife has said no more toys !

PS Thanks to all of you for responding and I do not have any issues with side issues being discussed as that is how we all learn new things.

madsen,

Dave's picture is likely the same filter/primer pump that you have , but on a completely different engine (in-line 6 cylinder in side radiator coach) and therefore different location.

Put some fresh fuel in her. If you're on shore power, fire the block heater at the rear switch for a few hours, hit the boost switch on the dash to tie the batteries together, keep your foot off the throttle and see what happens. I'll put my coach bucks betting she'll start! Shut down all switches after she fires.

I posted the pic just to show what your hand primer pump might look like. As Brett said, my coach is different.

So I got the Cat started and home but not with out major effort and worry.
To answer some of my own questions this coach has only one fuel filter and it is mounted on the back passenger side. It is a Racor fuel filter water separator. It has no manual priming pump and no electric pusher pump.. It does not have the cat 2 micron fuel filter located on the front of the motor.
Short story is that we used air pressure from an on board compressor to push fuel from the tank. We used the relief hose location to put the air is and then primed and bled until we had fuel past all the fittings and into the injection pump. It then started and ran well. We found a few more leaks including one major one on the injection pump.
By the time we were done we had less that 2 hours of daylight and still had not checked the air system or aired the tires or made sure the brakes worked or checked fluid levels and conditions. So we drove home 2 hours. Went back next morning and started again to work the systems and re-fix some fuel leaks . Prepped for the possibility of having to put on a electric pusher pump to keep it running because the injection pump was leaking fuel out the bottom. Died a number of times more and did not get home till after dark. It had snowed the night before the second trip so the roads were snow packed and icy on the way back to the coach.
Luckily it had almost completely melted off and dried out but had to contend with a 40 mph crosswind more than half the way home. I had trouble judging the distance to the middle of the road as it sit so high and one cannot see how close you are to the center-line easily. I am used to driving a school bus even on ice and snow but it was draining to say the least. I have posted questions about the electric fuel pump location on a separate post and just tried to wrap up the questions I raised on this post.
Thanks for your help
JOHN
