RE: The Fuel System Upgrade Project

If you mean the polishing filter (the one on the right), it's a bypass line for fuel transfer without filtration. Not sure WHY I have that, but I saw another rig that had it, so, like you, I figured it was common in pro setups. Think I should nix it?

RE: The Fuel System Upgrade Project

I'm not sure what it does- I'm new to this too. Is your polishing filter on the suction side or pressure side of the pump? Maybe somebody in the group can explain what the by-pass hose does.
Now- what if you moved your polishing filter slightly left, added a 90 degree elbow facing down out of the pump- then faced the barb fitting at the "t" straight up. If those two fittings were aligned you could complete the connection with one short piece of hose. Would that work?
Also- the barbed fittings you have- do they require a clamp? They are not what I know as "push-on" fittings.

It really wouldn't solve much. Still have the problem of the pump output not clearing the motor easily.

All are clamp-on, but one (output of the second of the multi-stage Raycor on the far left, but the hydraulics guy swore it can be clamped too. I am going to try and double-clamp them all.

Tom,
Is there a way to come straight out of the pump output, maybe 4-5" then a 90 straight up? Might even use a section of hose for this.

Tom,

Bite your tongue! Permatex indeed. Use the Loctite. My wife works there and I need her to keep me and the boat in the manner to which I ave become accustomed. Permatex used to be a part of Loctite but was sold off.

Only kidding, Permatex is a good product.

The Fuel System Upgrade Project

Tom, I don't know what the additional line just downstream from the filter and upstream from the motor would be used for.* I would suggest you deep six that.* Also, please remember that the Procon pump will put out 250 psi.* That was why I suggested A-1 wire braid hose with JIC to NPT fittings.* Lesser hose will work as long as you always remember to open a valve so the fuel has someplace to go...

Permatex did not work for me, but my mistake was using stainless pipe fittings, and I am sure you will have better luck with the brass fittings you purchased.

p.s., now that I look at the picture again, I'm not sure what the extra line and 3 way valve upstream of the filter will do either...

RE: The Fuel System Upgrade Project

Take a look at the new design in the new thread. To finish up this thread, I am posting a few pictures of the old rig set temporarily in place in the bilge.

I can't thank you guys enough for all your help so far. It's been nothing short of amazing!

Tom-

1) The new spin-on CAV filter modification.
2) Looking in the engine room at the rig.
3) The rig closer view
