Strange engine question

Hello everyone- I have an unusual question about running my RV engine on a gravity fed fuel tank-just to keep engine excercised until I can replace the fuel pump. I got it jacked up-then my health took a dive- now I just want to be able to start it from time to time- I have a 2 gallon tractor gas tank with shut off-I could mount above the engine access-directly to the carb-Its a Dodge 440 cuin- 4 barrel. Do you think it would work for just temporay? Thanks-Al

It should work. I've seen cars run off coffee cans before.

Mame sure good ventelation, gas tanks make good bombs.

Best to place tank outside on ladder with long hose.

Pour in one gallon max, wait for flow to carb, start and let it run it out.

Gravity fed fuel tank to engine carburetor was the norm back when we had Model A Fords running around. It should work fine. Hope you feel better soon.

There is a problem you may run into. A gravity feed to a "modern" carburetor may not supply enough fuel for road load, let alone any climbing or acceleration. The discharge pressure of a typical engine driven pump is in the 5~7 psi range and that is about the same as 15+ feet of vertical head.

If by "excersize" you mean to idle the engine, as an engineer that did engine testing for many years, let me advise you that there is nothing good that happens to an idling engine. We use an idle test for many years to make cam/valve gear problems show up fast.

Rather that "exercise" the engine by idling it for too long (any more than warn up enough to drive), why don't you read up on how to properly store the engine. That is what boat people do all the time. I have put and engine "to bed" and one case it did not get restarted for eight years. It started right back up after the proper preparations were made and it is still running.

Storing an engine for an extended period of non-use is really pretty simple.
Simple instructions: (they are less than complete and all encompassing)
- Put new oil in the engine.
- Run it until it is warm.
- Shut off the fuel supply (somehow).
- As the engine coughs off due to lack of fuel, pour fogging oil in the intake.
- When it is cool, close of the intake. Close the exhaust too - if practical
- If it may be unused a very long time (years) remove the belts and coat the FEAD sheaves with a rust inhibitor. (If you don't, the belts will be shredded by the rust on the sheaves.)
- Find someplace to store the battery.

It really is that easy and it really is that good.

Strange Engine Question

Well guys- after tinkering with this- I have decided to install a used in line elec pump just below the temporary tank, it came off one of my old tractors-low press. I'm mounting the whole rig, outside, up front under engine access cavity, outside of fire wall-away from electrics, lots of ventilation. Will let you know how it works-might even be a good idea for an emergency fuel supply problem-Thanks-Al

Don't listen to this guy. He sure hasn't read your question. I can fill your head with a lot of technical garbage and the facts will be the same.
What your trying to do is fine.
I used to have a car collection and would only drive one each year. The others sat and I would start them regularly,never had a problem.
Still have a couple that havn't been able to use because of family health issues. I start them at least once a month they have never been an issue.
Just get them up to temp and change the oil per season if you think it's necessary.
I am also a licensed mechanic (CANADIAN) for 40 years and own and maintain my own aircraft.
GO FOR IT

This worked for once and it was strange

My fuel pump went out on my ford f250 towing my trailer 20 miles into a nat. forest, I took thebulb and hose off of my boat motor tank and laid it on the drivers floor and attached it to the fuel line from the tank and to the carberator, I pumped it with my foot and it woked perfectly, well it actually was awesome apartently the check valve in my fuel pump wasn't working and the bulb has a check valve in it, so it basically made the whole system work perfectly whithout even pumping on the fuel bulb, I replaced the fuel pump 6 months later and the little bulb was still working as a check valve for the fuel pump.
Try it in your fuel line and it may just work for you.
