I might be interested after you try it out and make sure it charges at idle... I had alot of bad experiences with U/D pullies on mustangs. Damn things wouldn't want to charge at idle especially if you had a stereo system.

If you need a hand paddling, let me know. 

Haha! Will do.

The mechanical pump might have low pressure but it hasn't left me stranded. Yet...

I think I'm just gonna reinstall the mechanical pump and start checking and replacing all the fuel lines again. I'd rather have low fuel pressure than none at all.

When the tanks get emptied after another trip or two on the water I'll probably pull them and check the pickups.

Probably gonna run steel braided lines too. -8 sound big enough?

Pics are blurry, but looks like normal markings on the pump lever to me. Wish mine looked that good! Lack of lubrication it would be worn down visibly and measureably, IMO. It's gonna get marks on it, lol, that's just kinda the way they work!.

It is a little worn down. The left side of the silver mark is definately worn I can feel the dip with my finger.

Thanks for all the replys. I appreciate it.


As far as the 1/2" line goes the reason I didn't do it is because the electric fuel tank selector valve and the fuel water seperator both have 1/4" NPT fittings. Which means even if I upgrade all my lines to 1/2" the I.D. of those fittings is only still probably gonna be 3/8" or less. I'm running a mostly stock 460, probably only about 350 hp. So I can't see how the 3/8" fuel line is the problem in my case. Another reason I went to electric is because Clay Smith said there was excessive wear on the fuel pump shaft. I'll get a pic up ASAP.

I'm thinking the reason the electric pump quite on me is because I was ideling for so long and the motor wasn't using any fuel causing the pump to overheat??? IDK???

I'll be rite back with the pick of the Clay Smith pump.

For all those who have been watching my ongoing saga with fuel delivery issues here is the latest update. I checked all my hoses, fuel water seperator, fuel tank selector switch for restrictions and every thing was fine.
Clay smith pretty much told me that in order for his pump to work properly in my boat that I would need to upgrade to 1/2" I.D. hose and or run braided lines. Don't really want to do either of those at this time so I ordered an electric fuel pump to try out. I ordered the Jegs equivelent of a holley blue (holley only offered a 30 day warranty and jegs offered 1 year). Jegs told me it was bassically the same as the holley blue without the holley sticker on it.

I plumbed in the pump and mounted it as low as possible (inlet and outlet are at least 2-3" lower than the bottom of the fuel tanks). Took it out to the lake today and the pressure seemed to be better from what I noticed. Before the regulator it was about 11psi and after it was 6.

Now onto the new problem. As I was idleing into a no wake zone area in a cove the fuel pump decided to quit working. It was still running but was not providing any pressure and was very HOT. After I let it cool down for about 20 minutes with the hatch open it started rite up and was fine. I hurried my ass back to the dock through huricane like conditions praying the damn pump didn't quite again.

So did I get tricked into buying a shit pump or is this a common problem with electric pumps with an engine hatch??? Too much heat at low speeds??? I'm really at the end of my rope on this one... Running out of ideas... Seemed to have possibly fixed one problem (don't really know for sure cause I didn't have much time to play with it) and created another.

Can't really tell by the picture but are there any breathers or pcv in those valve covers?

I had a very similar issue with my motor when I changed valve covers, kept blowing the front and rear lifter valley seal on the intake manifold. Ended up having to put a tall breather on each valve cover in the front with baffles screwed in underneath to keep oil from blowing out.


Like this...

Ok so I got a call back from Clay Smith today and he said the pump is good to go. On his bench it put out 21 psi and didn't bleed down after 20 minutes.

He is thinking I have a restriction of some sort. Possibly the rubber fuel line on the suction side of the pump might be collapsing. Or he suggested possibly a clog or restricted vent from the fuel tank.

Any suggestions.

So I installed a gauge before the regulator and the pump seems to be the issue. It's only putting out 6psi cold and then drops to about 4-5 after it warms up. I pulled it off and am going to ship it out to clay smith tomorrow.

Did he get that CP?

We just had a bunch of boats in my front yard the other day, fixing, adjusting and tuning. Ordered a few pizzas, had a good time.

That sounds like a good time.

I hope to find the problem this weekend. I'll try and meet up with you guys if you go out this weekend. I should be out saturday for sure.

I think he means My boat may be headed his way, AGAIN, lol. Haven't confirmed this, however.........

Ray

Oh, ok.


I think I'm just gonna try and pick up another gauge first and make sure that's not the issue.
