My new fuel pump.

Got my new fuel pump in from Skidim. As you can see from the pic, I've run into a bit of a problem. The overflow hole connector, or whatever you call it, runs right into the oil pressure sending unit.

Anyone else run into this problem? Gary I know you said you were installing one of these pumps, how did yours turn out?

I'm wondering if this is soldered in. Could heat, remove, cut a bit off, then resolder. Maybe, but I would not want the heat to damage anything.

How about a different shaped sending unit?

Anyone have any ideas?

Thanks!

Above the diaphragm it is closed off, other than the hole to the tube fitting. There is a rod and spring that moves the diaphragm up and down, the rod goes through a small hole and connects to the arm that inserts into the engine.

I'll have to pull on the fitting a bit to see if it comes out. There's some kind of dried up residue that looks like it dripped from the hole. I was thinking it might be flux meaning that it could be soldered.

I'm sure we can figure something out before this new one fails.

David, that hex nipple with the oil sender should be removable Like Pete said, I think I would try to rework that to clear the fuel pump. I wouldn't suggest trying to re engineer the fuel pump.

I'd go to the hardware store and get the brass fittings you need to move the sender. Replace the hex extension with a shorter fitting and 45 up and out of the way. I had to relocate mine a bit when I tee'd in for a low oil pressure alarm.

That fuel pump way not be exactly true to original as most of the old ones I've seen the overflow barb angles up and out of the way.

Gary, If the diaphram ruptures the fuel will be forced up that tube and dump into the carb.

Not to get into a debate with anyone about USCG approved tubing but that overflow has always just been a clear piece of pcv tube.

Pete, I didn't really pick up on that, think I was stuck on the overflow since that was the initial converstaion. Besides, I try not to start arguements with people smarter than me.

Yes you can feel the air venting out of the hole when you work the pump. Like Eric said.

I compared this one to my old pump and although my old pump did not have the nipple mount, the hole was in the same place. Everything above the filter canister looks exactly the same as the old one.

I think I'll look into reworking the oil sender extension. Sounds like the way to go. Put that on this list for the winter. Along with the rest of the engine, stringers, etc.

I don't think I'll need the overflow line for the two trips I might make this year. At least I better not, that pump wasn't cheap and it better hold up for years before I need the overflow.

Same with the high pressure line to the carb. I know I'm supposed to use a certified rubber hose or metal line but I believe I'm going to stay with what came with the boat for my 1-2 trips. Skidim doesn't have a line that works with my carb and the rubber one is just to damn expensive. So I think I'll have to look into making one. That or perhaps I'll get a Holley over the winter and us the line Skidim offers for that. Either way, I'll have it taking care of before next year.

Boat goes in the water Saturday!

I'll definitely look into that. Thanks for the advice!

Does anyone use any type of Teflon tape on these gas fittings?

Vondy,

Any chance skidim sent you the wrong pump? They have two that fit Fords, one for PCM (item 0406)the other for Indmar (item 0438). The PCM one has the vent on the other side.

You know I sent them an email and asked, they said it would work. Or they said they don't see any reason why it would not work.

I think I'll try to move it as well.

unscrew the oil pressure gauge, unscrew the extention from the block that the gauge was mounted to, get a shorter 45 extention just like the one you removed at the auto parts or hardware store put the stuff back together call it a day. Hell just leave the extention out and screw the gauge right into the block problem solved.

Don't think that gargantuan sending unit will fit attached directly to the block but a quick trip to the hardware store for a few plumbing parts and he should be good to go.

it looks tight but I know I was able to remove it on mine. Regardless a short 45 will get it out of the way.
