Can't get the Beast to start

No the fork is separate

Good news.... sort of, primed using the output of the pump through secondary and through the racks. Quickly reattached the line pump, the beast jumped to life. For about a minute or so then died. Confirms the pump. I was able to suck fuel from the in line through the primary so strongly believe it's the pump.
Need to wait for c wrench to try and get it off. Now need to find drive fork.

You better check that is a RH pump in your photo easy to spot the difference the LH has the relief valve at about the 9 o'clock level the RH relief valve will be on the bottom

Please do post if the new pump install solves the issue. I know these pumps can go bad, but i guess there's a small part of me that wonders if this is something else...and not the pump. But I'm not experienced at all. So take that with a grain of salt.

It will not stay running until primed well. That pump will not pump air, as soon as it gets air you are done. One cheap way to prime is with a suction pump. They look like a grease gun. put a connection at the return line to the tank and suck fuel all the way through until there is no air left. You will need a cut off valve in the line to hold the fuel when you take the suction off. Most hardware stores have the suction pumps.
This did work for me over 10 years ago, but I still keep the pump in my coach.

I'll ask the dumb ?? Your bus isn't below 1/4 tank and sitting down slope on drivers side. Might not be picking up fuel from tank. Bob

BeastMaster · May 26, 2015, 10:03:02 AM

Robert, it should have had enough fuel when I parked it last week end. It does slop down a little but leans towards passenger side. The pump has been leaking for sometime. I always dripped more fuel than oil! I was able to get it out of the bus yesterday, however still have not found a way to get the plugs out of the primary fuel filter for a priming pump. I never thought of the suction process on the return line. The tank is confusing however with aux tank, generator, and aqua-hot lines. If I pinch off the aqua-hot return line and use that fitting, could I pressurize the tank and push fuel through the fuel pump? I'll look at the parts manual and see if I can decode the return lines. Maybe money spent that I didn't need to, however, it the leak is stopped than the work was worth it.

Those plugs usually have Loctite applied a little heat they come out,not a big deal to install a tee and valve between the primary and secondary filter where it leaves the primary filter

Thanks. I'll fire up the heat gun tonight and try again. Thanks.
BTW, the lines into the pump came off easily.

I don't think anybody has suggested this yet. The easiest way to prime any engine is to pressurize the fuel tank. It doesn't take much and you don't want to get carried away or you'll expand your fuel tank but all it takes is a couple of PSI to push fuel through to the engine. I use a circle cut out of an old inner tube and hold it around the filler neck with something - you can even hold it with your hand. Put air to it with a fitting cracked at the pump and keep pressure on until you have fuel flowing. Tighten everything up and it should start.

Hey Bob What's with you giving out Saskatchewan secrets LOL

Crazy but sure works good.

luvrbus · May 26, 2015, 02:03:23 PM

What do you about the vents on the tanks ?, it won't work on a Eagle with the 2 tanks btdt

Scott & Heather · May 26, 2015, 02:23:21 PM

I second the "Pressurize the tank" method. But I have an actual nipple I can attach a garden sprayer to by the primary so I thankfully can prime that way and have done so many times. I have what appear to be leakage around my pump but I never lose prime from sitting. Ever. Coach sits a year and a half and still never loses prime. Only time I've lost prime was running it down too low on fuel. Anyway, I'm following this closely. My gut still thinks this might be something else....I'm probably wrong, but I'm watching the thread daily for updates.

bobofthenorth · May 26, 2015, 07:30:02 PM

I guess it depends where the vent is Clifford. I've never run into that. Not that I use this method daily but I've done it often enough to know it works. If the vent is via a vented cap then that's not in the picture when you pressurize through the fill tube but if there's a separate vent then it obviously wouldn't work.

luvrbus · May 27, 2015, 05:55:46 AM

Done it many times Bob it does work just not on vented tanks
