We're looking for a nice, clean RV park in southwest Florida for January/February/March 2012. We prefer the campground to be within 5 to 10 miles of a beach, and price in the $700/month range. The last two years, we stayed in La Belle, Fla. Need new scenery but want 50-amp power, sewer and water hookups, Wi-Fi and cable. Any ideas?

ok ya'll. guess i go this alone......... thanks for your help with my post regarding regarding fuel filter problems. will close this one out. john

Not sure if I'm in the right topic section, so , if not, let me know .... I had posted a problem within the last several weeks about air leakage in my fuel system. While trying to solve this problem, I noticed my speedometer would register 25-35 mph while I as standing still. My mechanic had instructed me to put the cruise on fast idle, which i did, and then i noticed this problem. It wouldn't reset. Then when we found the air leak and solved it, after running the engine for a while I noticed the speedometer had reset to 0. Went out on the road to go camping....... no speedometer reading..... just 0 I have a Cat 3126b and a Allison 3000mh with the pushbutton shift selector. On my short 2 day (60 mile) the Allison seemed to work ok. The engine brake,cruise control and shifting seemed OK. Can anyone address this issue? Thanks John Wells

Brett: Ok, this morning my mechanic showed up with intentions of measuring for a small fuel line to feed the engine with a bucket, to try to locate an air leak. I suggested he try (your instructions in the "engine" section) to pressurize the tank, since this seemed to be the fastest test. He cranked up his compressor and removed the secondary filter. When the tank pressurized and fuel was pumped to the primary filter, it began leaking from the top of the clear plastic bowl. We inspected for cracks, found none, replaced the gasket and … "shazam," no more problem. We reloaded the filters and started the engine, which ran for about 15 minutes, and then it stopped and restarted several more times …. Thank you for your help. I plan to Join FMCA today. John Wells

Brett, I noticed another posting by you under (engine) concerning a filter problem by Jim..... you noted that cat part number 198-6378 was the correct filter for a single filter system. I have a two filter system and have been using the same part # filter as by water sep/filter. after noticing your post, I called my local Cat parts dept and the guy says he doesn't have a separate filter # for a dual filter system.... I know this probably isn't why I am having my problem, but should not Cat have a different filter for my set-up?

My mechanic got back with me. His contact at the FL shop says they would try to pump fuel from a separate container, bypassing the lines,filters and, if that works then start trying to fine air leak in the lines,filters etc. My mech. says I have a high pressure fuel/oil pump combo, and if it is the pump, they are very expensive. Being only a shade tree mech, it seems to me that if the high pressure fuel/oil pump was bad, half of the fuel would not be used up and the engine wouldn't run for 3-4 minutes, after refilling. the filters of course. he will have a new short line made up and try to get back over early next week. What do you think about involving the pump-- think there could be a problem there? Thanks again for your time Wolfe... John

Didn't see him with any pliers, but still possible. Is there any way for ME to check and detect leaks? Would the Freightliner shop be able to isolate a leak, or do they just start changing lines, etc.?

Brett, To make sure I understand your instructions let me tell you what I am getting out of this..... If there is an air lock from the tank to the primary filter or in the line from the primary to the secondary filter I should be able to clear this problem with the pump. Is that correct? Could you possibly have this airlock and not be able to clear with the pump? I have been filling the filters (as did my mechanic and the Freighliner mechanics do the same thing, then pumping 4-5 times, each stoke becoming harder and harder to complete. When I start the engine it runs very smoothly for about 4 min. then you can hear the engine labor, RPM'S reduce and just before the engine stops I get white exhaust. If there is an air leak, then it would not clear, but when I pump the aux pump it is very difficult to complete the last 1-2 strokes, which tells me I'm pumping fuel. Ii think I should just wait till my mechanic gets back to me and see what he has been able to determine from the Freightliner shop....... If you can shed any more light on this subject, please do so..... Thanks John Wells

Thanks Brett. The seals have been checked and rechecked. Fuel is not getting to the filters. After the engine stops I check both filters, and both are down by half. Its 5:12pm and I'm through for the weekend, unless of course I get a new idea to try. I don't expect to hear from my mechanic till about Tuesday. Will follow up then. However, I will be checking your thread for any new ideas...... Thanks ,,,, John

From the dates on your thread it looks like I'm late to dinner... I have been looking for info on a problem regarding new fuel filters/engine only runs 3-4 min. after remote mechanic fills both filters with fuel and pumps primer. He repeats the process. Fuel tank is about 3/4+ full. Rear of motor home is elevated with leveling jacks. this engine ran and started perfectly prior to this filter change. Mechanic has 18yrs experience with a local shop,,,, mainly marine engines, but then motorhomes. He is now pointing to the fuel pump and something that is incorporated with the fuel pump that has some thing to do with creating pressure for the injectors or valves. not sure exactly what he was referring to. I plan to talk to the guys at Freightliner to get their opinion and ideas. I have a 01 National Tradewinds LTC 39' with a 3126b Cat engine. sn# 8yl 80428. I have a Freightliner chassis and have two fuel filters and a manual primer pump. My problems is: this mh was running very well, until the filter change... we tried to start the engine as soon as he had changed filters and primed, as pointed out above...... After reading several threads on different sites I'm leaning toward an air lock between the primary filter and the fuel tank...... help.... John Wells
