Outboard fuel return

Do the modern outboards have a fuel return? I have two pickups on my tank, I think from when she had twins, or is one a pickup and one a return. Unfortunately some idiot removed all he plumbing before noticing

Nope, no fuel return on a petrol, diesel might be different. It's definitely a one way street with petroleum 🙄🙄


Sh1t happens

Two pickups, or a pickup and a breather?

Jetski's and Jetribs with Yam 2 strokes run out / return, but regular outboards don't.

Thanks all

So next question is where can I buy a new pickup and what type. I've seen lots of types, and lots of different materials. My stainless ones have corroded and they look a bit home made. Just a stainless pipe bent round with a lump of metal gauze resting on the end which was also corroded. Are they usually solid or flexible?

Thanks

Gt

Mine is solid and built in. I guess your's screw out? Your's may have suffered from water lying under the fuel in anoxic conditions. Levels of bioethanol are going to rise in petrol - if going plastic make sure any glues etc will resist ethanol. I remember a couple of fuel filters gumming up a couple of years back due to ethanol...

Thanks wilk

This is what I have..... It's a scorpion so glass tank as they all do. Grp inspection hatch, the can bus fuel sender which I fitted a few years ago and the 2 pickups. Boat has been laid up and the tank had had some work done on it. I filled it with water for safety when I was modifying parts and now the stainless has corroded.

I'm happy to replace with stainless again although I'm surprised by the corrosion. Equally happy to fit an off the shelf bit or whole new inspection plate. The current one is a pig to remove and replace, the seals perished and hymer used has also degraded.

The pickups have a 3 hole pattern, the canbus sensor has 5 hole which I made when it was fitted.

You were very very naughty to fill that tank with water!

I'm not a metallurgist, but stainless steel requires oxygen to maintain a rust free barrier on it's surface. If the oxygen in that water became depleted it may have effectively created an environment that allowed crevice corrosion to occur. Poly will have a learned opinion on this theory

Personally, if the actual corrosion was superficial, I'd clean it up and polish it and refit the lot with decent sealant. There was a thread a couple of years back when Osprey fuel hatches were failing - a product was recommended? With FUEL in the FUEL tank, a repeat is unlikely

Willk; Not to hijack the thread, but what was the source of the gumming? I've heard of problems with 60's and 70's era vinylester fuel tanks and ethanol, but not much more than that.

It occurred on a RIB in the Round Ireland 2013. There was a spin-on fuel filter fitted and it began to clog up unexpectedly after it's first fuel up in the Republic of Ireland. We have a higher percentage of ethanol than the UK. Apparently we need an ethanol friendly filter? The tank in question was stainless. Possibly there was a release of old gum once the ethanol came into play?

I was discussing with my dad if the ethanol levels had elevated as much as was predicted.

Metal brite cleaned the rust and stainless off and new gaskets and stainless nuts and bolts purchased. Gonna keep as was. Thanks for help.
