New 1995 Eurovan Camper owner

[[email protected]]

Hey folks - new owner here, picking my 1995 Eurovan Camper up tomorrow morning. There are a couple small issues to resolve. I’m hoping there is some experience here I can use.
The heater fan doesn’t work; I assume it’s the switch. Thoughts and ideas?
The second battery charges while the van is running, but will not power the system when the van is not running. Where should I start?
Previous owner told me it is very slow to fill with gas, probably a venting issue? Again, where should I start?
Once I have a pic, I’ll post it. Thanks in advance!

Start with the fuse for the blower. Then look for 12 volts at the fan with switch on, work backwards to find fault

It’s likely the second battery has been butchered from stock, so you will have to sort out by inspection.

Vents in fuel tank do need cleaning , slow filling is usually plugged evap system

Thanks Abscate!
Can you clarify what you mean by “butchered at stock”?

The typical house battery is a lead-acid deep-cycle. If you are lucky, and the battery is perfectly maintained, these will last a few years at best.

When they fail, they tend to fail in a manner that can be deceiving: the battery appears to charge up to a normal voltage, but it has almost no capacity, and quickly dies when under load.

Bottom line: you'll almost surely want a new house battery. Many of us have upgraded to LFP (Lithium Ferrous [Iron] Phosphate) batteries which are vastly superior. The only downside to LFP batteries is they don't take charge below freezing temperatures (although newer self-heating LFP batteries are available).

I have a theory about the charcoal canister/slow fill. You may or may not want a tin-foil hat for this one.

My EVC had not been driven a lot for a year or so. I bought it, and parked it for the winter (not driving too much). When I went to put gas in it for the first time, the pump kept shutting off. I didn't know if it was a pump issue, or something with the filling system.

2nd fill was better, but not perfect.

3rd fill was great.

My theory is that the charcoal canister collected a bunch of vapors while sitting for so long. A few tanks and 500+ miles got it cleaned out.

All this could be hooey, or just a red herring, but it worked for me. I'd suggest you fill it slowly a few times before diving into a repair. (And I found that not putting the nozzle all the way in the filler - allowing some air to enter/exit around the nozzle - made filling a bit easier.

Welcome to the family. You found the right place for information/reassurance.

A common story with the "hard to fill up" scenario is that the tank was over-filled. With extreme malice.

My personal story originated in the state of Oregon which, until recently, insisted that only "professionals" were allowed to fill up the gas tank. No self-serve.

Said professionals, behaving professionally, knew that gas tanks really like "a little extra" and would give one, two or three more tries after the pump naturally shuts off. Professionally.

This overfilling forces liquid gasoline into the charcoal canister which basically clogs it, but (so the story goes), gasoline will eventually evaporate, and things may get back to normal.

Of particular note, the only 2 states in the US with this "no self serve" law were Oregon, and New Jersey.

I notice the OP @dmeysembourg is within striking distance of NJ. Maybe your van did some gambling trips before you bought it?

TLDR:

* gas tank fill problems may be due to a gasoline-saturated carbon canister, in which case normal driving, with several refills - as long as you don't over fill it - may lead to improvement.
* other evap problems such as fumes, are often solved by a new N80 valve or new gas cap, which are under $100 and super easy to replace.

If neither of those fixes your problem, then you go into expert mode (and cry a little).
