Diesel fill problem.

[jmcmonagle]

Purchased a 78 Pearson 323 with Volvo md11c about a month ago.
At most marinas can not get diesel pump filler into the fuel fill.
End up filling with funnel.
I suspect it's original fuel fill with 1.5" hose.
Will putting in a new fuel fill help or is it hopeless with a 1.5" hose?
Any suggestions?

Thanks

Same problem.  I just fill slowly.  Never used a funnel I guess still have to go slow.

Some marinas have adapter, like the one I get my fuel from. Adapters are out there.

Built back before there was low sulfur diesel and such. I use a filler neck/spout of a plastic gas can.  ecstuning sells one for VW that works well, $8.00 No affiliation.

In my case only able to get hi speed fill in a fraction of an inch.
From google a high speed filler is 1 3/16"
For it to fit hose part will have to be about 1/8" thick or less.
At a marine store they had a cheap plastic gas filler in the inside large enough.
The hose part as real thin.
Had  problem measuring the inside diameter  on my filler with caliper.
I'll make another attempt but but suspect the hose part is real thick.
I've seen  no dimensions on the fillers I've seen on line.

I'm willing to change the fill buy an adapter that is known to work.

Just a couple of thoughts you might want to consider the MD11 burns about .5gph.  I lived aboard and sailed/motored a lot. Usually only filled the tank once a year if even that.

You could probably get a machine shop to cut down a brass pipe or plastic pipe to whatever size you needed for a fill adapter.  The plastic one I mentioned from ecstuning could be sanded or ground down to fit but should work as it is. Comes with it's own sealable jar too so you don't get diesel smell in the boat when you store the funnel.

An "inside caliper" would be a good tool to measure the deck fill you have.

Hope this helps.

Was not able to get inside dimensions from manufacturer or venders for less expensive ones like Sea Dog.

Replaced with a new old stock Perko Diesel Fill Chrome Part # 520-D00-CHR  from ebay.
I could see from the photos that the hose fitting was thin bronze tubing and not thick casting.
It has a much larger hole and uses a stranded ss wire instead of a chain.
Well over the size  limit for a high speed fill.
The flange is a bit smaller and the holes are different.
Filled the old holes and with careful placement the flange covers the old holes.

It will be a long time before I will be filling to verify that it works.

Attached is photo the pretty well shows the difference.
