Farrar's car blog

Farrar,

Did you drain your tank first? Do you use the stock DMC baffle?

I've got a tank dissection next week.

I was thinking of literally pumping the fuel via the fuel pump itself (jump RPM relay) into my Jeep tank, with a filter somewhere along the way.

This will work, just make sure you are moving good gas or you'll clog up your jeep.

That looks like an Airtex pump end -- did you go with another Airtex unit?

Totally.

This is to investigate the bucking and stalling I've had after about an hour of traffic idling. Pretty sure I'l going to find some debris and a rotten pick up hose.

Could also be a collapsing pickup hose, especially if it is an original hose.

Yep, Airtex E8090. $63.99 at O'Reilly's. But not normally in stock, so I bought a spare.

Thanks for that -- I will move those wires! Stock cap will not work -- has two holes and I would only need one; I am installing a splash shield behind the pump. Will illustrate with video tomorrow.

My Airtex pump failed 150 miles from home today. Fortunately I had a spare Airtex pump and was able to get back on the road after a quick road side replacement.

This was my first fuel pump failure but given our luck with Airtex pumps I do not trust them. I picked up the made in china pump at Autozone today for my new spare. I will not be buying anymore Airtex fuel pumps for 16510.

I'd still say throw a stock cover on their and plug the other hose opening. Water has a funny way of finding itself there.

I tried the Mr. Gasket (made by Prestolite) pump on one of my church's school buses, but was disappointed with its output. It only registered 4 PSI on a dash pressure gauge, dropping to zero as the needle valve opened, rendering the dash gauge useless.

These Airtex pumps seem to be all over the map. John Marconi installed his pump Spring 2009 and is still running on it. I believe Bob Babcock is still running his first pump, including trips to Michigan and Pennsylvania. My first pump lasted Spring 2004 to Spring 2008, at which time its death was caused by a piece of sucked up epoxy (you know who's pickup screen).

Poor Farrar, meanwhile, goes through a pump every week.

What kind of failures are you experiencing? My epoxy killed pump just sat there like a bump on a log (didn't do anything). I lost one pump to what appeared to be bearing failure (jumped around so much it was difficult to hold in my hand). It is possible my third pump did not die (the car bogged down just as Louie and I were passing an off ramp, so we zipped off the interstate, into the gas station at the top, and threw the spare into the tank -- it could have been a gust of headwind).

The pump currently in my tank got me Alabama to New Orleans, then went to/from Lexington, Pennsylvania, and DC twice, but I won't hesitate for a second to throw my spare in there if necessary.

I'm going to respond to this in the carb thread for sake of constancy.
