Vanagon Fuel Pump Noise, Filter?

I think my fuel pump is making a whining sound (79 2L FI bus)... When I'1000 idling the bus I tin can walk to the dorsum and hither virtually a whine from what I think is the fuel pump. I've stuck my caput under the motorbus and it seems like the pump is making a pretty loud whirring racket.

The motorcoach sabbatum for 7yrs with what looks to be a generally total tank of gas. We drained the gas completely which came out clear with no rust or particulates and replaced the fuel filter although now I call back I probably need to lodge another and supercede the new one in the side by side 1000 miles.

Anyway I'1000 worried the pump will get out or does it normally make enough dissonance you lot tin hear? I'd rather have the part sitting adjacent to me so if/when it fails I tin can simply pop another in at that place.

Side by side problem is finding a new pump. I see BusDepot has them but they are 160 for a new Bosch and 100 for some other brand! I'yard thinking I demand to just see most finding a spare off somebodies parts bus for twenty bucks or something.

What say ye belatedly bay freaks.

They get noisy if they are starved for fuel. Check the filter and the flow from the tank to the filter - at present. My tank did non have rust or gunk, but had a few small chunks of rubber rolling around in information technology from when a PO cut the unleaded-fuel-merely restrictor out of the filler neck. Occasionally, a rubber chunk would get sucked into the outlet pipage and the pump would whine horribly. Sometimes, it prevented the Bus from starting again. I bought a new pump before I knew what was going on, thinking it was the problem. Information technology was a waste of money.

Y'all may want to pull the tank out and see if there's any droppings like that in information technology. It tin can be washed without removing the engine - just loosen the moustache bar and lower the engine a chip to make room....

The starving them for fuel too makes them overheat.

Try drawing fuel direct out of a 5 gallon can (but brand sure the tank will accept another 5 gallons of gas and not run over) and see if the noise goes away. If it does, do as Don suggests and driblet the tank before yous burn up a $160 fuel pump.

Endeavor drawing fuel direct out of a 5 gallon tin (just make certain the tank volition take another 5 gallons of gas and not run over) and meet if the noise goes away. If information technology does, practise as Don suggests and driblet the tank earlier yous fire upwardly a $160 fuel pump.

You hateful while the pump is however in identify, remove the fuel line from the tank and put it in a 5 gallon gas can?

This could be directly related to your stalling under load. Fuel starvation.

That would be nice but how do I examination information technology so when it but dies nether load?

I guess if I didn't screw up the timing some how I'll get pull and check the filter and give information technology some other go.

Check out your stalling thread. VWlover gave a good rundown on how to test the volume of the fuel pump.

Mail by **Adventurewagen** » Wednesday Sep 19, 2007 half-dozen:45 pm

Yes, a most excellent test. You know I almost merely combined the two threads having thought information technology might be related but it seemed similar as well much of a coincidence that I had the issue later changing the points and timing the vehicle.

Post by **Westy78** » Wed Sep 19, 2007 6:47 pm

Information technology's possible that irresolute the points has something to exercise with information technology just since it happened with both the Pertronix and points I remember it's a coincidence.

Post by **Adventurewagen** » Wednesday Sep 19, 2007 seven:01 pm

I guess. I mean the pertronix had a visible crack and was barely keeping the machine moving. I can reliably drive around in 1st and second and if I just don't punch it I could drive around all 24-hour interval nether 15mph

I'll get out and run the fuel test tomorrow and see how information technology'south pumping.

Is there any way to make clean out a filter if you don't have another one? I have a new i on the bus with say fifteen miles on it total. Can I utilize gumout and clean whatsoever crud that may take built up if it doesn't look likewise bad?

Post by **Westy78** » Midweek Sep 19, 2007 vii:04 pm

I guess you could try to back flush the filter with more fuel. Don't know if that will practise much though. I'd be worried about the Gumout maybe breaking downward the filter media?

Meet if y'all tin can still blow through the filter. If you can, that is expert to go.

Rig up some fuel line to draw the gas from the can to the pump and see if information technology still makes the dissonance or cuts out nether load. It should suck about a Liter in 30 seconds or and so and you lot volition not accept a long ways you lot tin can bulldoze.

I like junk in your tank.

A little tardily to this thread (sorry, been away for a while), only I had the verbal aforementioned problem with a noisy FI fuel pump on my trip this summertime. The noise was a whine, just like you described.

The problem was a chock-full fuel filter. Fortunately, I proceed a couple in my spare parts kit. Swapped it out on the side of the road, and drove off on my merry way (with a quiet fuel pump).

Same with me.. heard the whine, idea oh crap only inverse the filter start to see what happened. Whine went abroad. Hey.. maybe I could employ that on my wife and kids? I wonder where their filter is located?

Post by **Gypsie** » Wed Sep 26, 2007 7:03 pm

Good tips all.

every bit far as wife and kids, i'd rather keep the wine close at mitt...or better however copious amounts of beer!

Sorry, my heed seems to wander back to that track quite oftentimes.

back to tech talk...

Is it possible that even after draining what appeared to be a clean tank of gas, the sitting around left a flick of 'particulate/stuff' on the side or bottom of the tank walls that take go dislodged/stirred up and get sucked down the line and hence clog the filter sooner than expected? only a thought.
I like the ready footstep though (fairly inexpensive and easy part to replace). if you do cut open the i being replaced and explore.
