Ask Bill about carbing a DeLorean and other K-Jet/Carb tangets

[Farrar]

Take out these two components:

Attachment 4001

Their only purpose is to position the pickup screen lower in the tank.

Once again, I am cursed by being an early adopter.

My pipe cap is not tapped for 1/4" NPT.

There is no bushing in the pipe cap, just the close nipple, which will not come out. I've tried vise-grips and a hammer, and it won't move. Now I have a reducing coupling stuck in the bottom of the pump carrier, and that close nipple stuck in the bottom of the pipe cap.

Grr.

There has to be something at the bottom -- a close nipple isn't long enough to go into the pump and extend all the way through the pipe cap.

I just pulled the pump out of #5939. It has a custom piece of brass tubing instead of a collection of brass fittings. I bet yours is identical.

My pipe cap is tapped 1/8 NPT. The tubing is threaded long enough to extend through the cap and into the pump.

Do you have a 1/4 NPT tap? If so, just convert your carrier into a later style (I buy the brass fittings from Lowes -- I like their barrel connectors better than McMaster's).

It looks like this:

Looks just like the picture -- male on both ends. This has 1/8" NPT threads on it.

I managed to remove the coupling between it and the pickup screen, but that bit of pipe is stuck solid in that pipe cap.

It's a custom piece of pipe. I cut the threads myself. They are at least twice as long as standard threads, to extend through the pipe cap and still grab the pump.

The pipe cap is just aluminum -- it should spin right off (unless you've managed to get a fitting stuck on the other end...).

If need be, just cut the pipe off and use the stuck fitting to spin the remaining threads out of the cap.

Totally unrelated to Farrar's fuel carrier issues:

Do you typically leave the cover off over the pump like the photo a few pages back? What keeps water from collecting on top of the pump? Does this contribute to the short life you are seeing?

I took off my fuel pump cover after converting and gave it away as part of my trade for an engine. Not having it may have caused my fuel pump failure, but the inside of the fuel tank did look fine upon inspection.

Anyway, I was doing some work in there today anyway and decided to install a fuel pump cover. I picked mine up at the dollar store. I believe I got a package of 25 fuel pump covers for about $2 or $3.

I reiterate: frame rail pumps are designed to get wet.

Factory design:

I don't like water in my boot, so I rigged up a splash guard for the primary culprit (windshield plenum drain).

The argument that water is causing pump failure is a Red Herring. I think your problems are electrical. Consider this: what has failed on your pump: mechanical drive components or the electric motor itself? Both of my pump failures were mechanical (one sucked up piece of epoxy and one bearing failure), neither of which can be blamed on water exposure. My pump is grounded directly to the battery via two channels: the original frame ground and my ground bus (the frame is attached to the bus, which is itself attached directly to the battery). Electron supply is not an issue.

Just FYI, the Spectra E8012S, which is made in China and available at AutoZone, comes with female 1/8" NPT threads on the bottom for attaching a fuel pickup filter (included). The pump has a 1/4" hose barb directly on top, so there is nothing to screw in and if you mount it in the boot the hose will stick straight up, but there is enough room to close the access cover under the spare tire well. The pickup filter included with the pump also has a 1/4" hose barb. It's a perfect fit for Bill's "in-tank" solution.

The pump comes with a one-year warranty, so keep your receipt.

You can walk into any Autozone, nationwide, without your receipt and they will gladly swap it out if you bought it from Autozone.
