fuel problem

Hi Richard T!! I have a 88 325 and when purchased in eastern canada 4 years ago it had been sitting for 9 years, I drove it home here to calgary alberta I had similar problems would go 4 or 5 miles the quit! I ended up changing filter at electric fuel pump also along the frame behind step and also filter in carb! helped but did not fix problem!! Then I changed electric fuel pump at tank with the best pump I could find as the fuel has 30 feet to get to carb, Changed plugs and wires and on my way back some 3000 miles changed fuel filters again! I ran premium fuel with a cleaner every tank fill the first year! I have changed filters again 3 years later and have had no problems! I found a 1963 olds fuel line filter with glass bowl and this winter will put it in, I may not need it but just want to see if any more crud is in my tank! Jonathan

I agree with that statement about a glass fuel bowl/filter.
I have several of these on my vehicles bought from local autoparts stores and I love them!

You can see instantly if fuel is flowing, and the color of it, and if there is any sediment...
The chrome ends unscrew and the filter elements are easy to carry and cheap.

I put one on the Genset fuel line on the MH, but have not put one on the actual motor yet because I want to find a larger capacity unit with a fuel pressure regulator and gauge built in..
I want one like the good old Malpassi Filter King... even will save gas because it is really good at dialing the FP perfect. Had one years ago and loved it!

Looks like this...

just purchased a Airstream 310 31' 454 chevy engine. Runs smooth, starts up great. When push pedal down motor backfires and loses power. Was told spary wires n plugs changed n rebuilt carb. Think maybe a wire or 2 maybe misplaced. Again thinking, Fuel Filter maybe clogged cause no such words about the filter with 80 gran miles on the coach. where is filter located? know the wiring diagram already.

"When push pedal down motor backfires and loses power. "

Our 310 did this when we bought it after it was warmed up. Turned out the coil was going bad.

I've had the same thing happen with a bad coil. Not that expensive to swap out and if it turns out to not be the problem it's always good to have a spare on hand. It's no fun breaking down in the middle of no where

That is also a sign of the electric fuel pump not delivering sufficient amount of fuel. If it starts backfiring and you partially let off the accelerator and it stops backfiring and picking up speed; resulted in my replacement of the fuel pump and fixing the problem.

I had those glass fuel filters before and a mechanic buddy told me to get rid of them because the glass can break and cause a fire as he had seen happen before. My dad had them on all his cars in the 60's with no problems, but I heeded the warning and chose the metal canister type filter. I actually dropped one of those glass ones accidentally and it broke rather easily. But I don't think heat would crack it, as they're tempered.

Water in the gas will do it too. That was a reoccurring problem till I noticed gas on the ground as I was filling and found the the fill hose to the tank was dry rotted.
The Holley fuel pump not functioning became a problem also. After replacing it, rebuilding it and replacing it again I found a wiring problem. Seems, when built they make several crimp splices to the wire between the front and the back. I found no voltage at the pump along side the road one day. Found the wire to the running lights and scabbed a piece of speaker wire over to the pump: turn lights on, pump run. When I got home I pulled a new one piece #10 wire from front to back. No more problems.
While I was at it, I ran new #10 wire to the air ride compressor in the back corner as well. Another problem waiting to happen for It had many crimped connectors in it as well

Smile Slow to Refuel

I have a 195 Classic 36 diesel pusher which I bot in '09 with 27,000 miles on it. We've taken it on several long trips and it now has 45,000 mile. We love the motorhome and plan to keep it until we can't travel anymore. My problem is that when it is time to refuel, after 25 or so gallons, the fuel starts backing up out of the filler nozzle and spills all over the place. Then it takes about 20 minutes to trickle in the rest of the fuel. I believe the problem is because the fuel filler pipe enters the fuel tank midway on the side and not into the top of the tank.
Has anyone encountered this problem and if so, is there a solution. I've gotten to the point where rather than stand for 20-25 minutes refueling I just put enough in to where it starts to blow back and leave with only half a tank of fuel. Remember, this is diesel and it is bad about frothing up unlike gasoline.
Thanks for any advise,
Dave Ramsey

First thing I would check is your fill vent. I bet it is blocked so when the fuels level covers the fill pipe there is no where for the air being displaced to go.

There should be a smaller fuel line coming off the top of the tank at the same side the fill pipe is. follow it to where it connects outside. You can try blowing some air in it with the fill cap off since air should go both ways. I don't know if they have a check valve or not, but am guessing no. Don't blow too hard, you don't want to displace fuel out the fill port!

Dave my 82 has the fuel hose going into the side of the tank near the top. It feeds at a small downward slope and yes it feeds very slowly. With the average pump I put the nozzle on the slowest self holding notch and then I have to pull the nozzle back at least half way or more out of the filler pipe to get it to fill. If the nozzle is in too far fuel backfills in the pipe and shuts the nozzle off.

I agree it does take way too long to fill the tank but I take the time because I'm sure it is less time than it takes to get off of the freeway, find a station, get into it and find a pump, fuel up, pay and get back on the freeway. To me taking on fuel is a big pain in the rear so I don't stop until I'm running on fumes and I fill until I see diesel at the top of the fill pipe.
Cheers, Dan

I agree with Dan, it takes FOREVER to fuel those babies and his method of tanking up is mine , as well. The slowness of the fill sure gives you time for conversation with admirers, though!

Dave and Dan, thanks for your replies.

I have blown air through the vent tube but haven't pushed a snake through it. When I blew air, it seemed clear but I'll try it again.

When filling up to capacity, it takes the fuel so slowly that even the first notch on the pump nozzle is too fast so I have to stand there it seems like forever. It sound as tho' this is a design flaw in the fuel system.

On another subject, I just had a Banks Power System installed on the engine but haven't gone anywhere yet. It is the Stinger and the Power Pac system. Does anyone have experience with Banks Systems on their diesels?

Dave R.
