Don't use that grey hose.

Don't use that grey hose.

What's up with the grey hose?????

I thought it was the cheaper hose that ethanol tears up more easily. It delaminates it on the inside and clogs your carbs / efi.

That was half of my problems with my new motors. Ran all new grey hose and the inside came apart and screwed me.

I've heard too many horror stories about it and too many people saying "this brand/type of grey hose is good but that one isn't" so I won't gamble on it. I have some in my boat right now but I am replacing it with the good stuff before I start it this season.

Fuel question

I'm getting a little out of my knowledge zone here.

My boat was wired with electric fuel pumps with switches on the dash. Can someone point me to fuel pumps that I can install? If I'm understanding this right and I think I remember reading Instigator's build thread on his Sonic; I can install a simple thru flow fuel pump to take the place of the primer bulbs. It seams like I could buy a low pressure fuel pump turn it on for a few moments and then start the motors. Am I missing something?

 

[atc250r]

If the stock pumps are still present and functioning you can use electric pumps in place of proper bulbs. If the stock ones are bypassed you'll be able to do the same but I'd be more inclined to make sure they'll flow the GPH needed. Either way you don't want too much pressure.

Holley red pumps.

Thanks guys. I went to Summit and I saw the Red pumps but wasn't sure if that was the correct pump for my application. Now I see there are Holley marine pumps.

For some reason I thought fuel pumps would be a little cheaper. I may just go with the tried and true primer bulbs.

Done, I think your on to something.

Coming along. Won't be long now for the smiles.

I run the holley red marine pumps on my boat. You need two pumps and make sure you use 2 relays. 1 per pump. You will not be able to shut them off when running.

my 245 runs holly red as stock!

Fuel Line Assembly

I'm going to go the old fashion route and put bulbs in. Which ones are the "good" ones?

Don't buy that stuff. Get OEM bulbs. Doesn't matter which ones, Merc, Rude, or Yamaha. If you ask Randy he'll tell you which pumps he uses. They're Purolator and probably not much more money than OEM bulbs. I asked him a while back but can't find the thread.
