2000 Disco II 140,000 miles. Been having a problem with my Disco having to be cranked on several times to finally make it start, then it sputters for a few moments and has no power. After it gets past its "morning sickness" it runs fine, unless killed out and left sitting for a few moments, then the whole thing starts over. My mechanic and Disco Mike have this diagnosed as the fuel pump not holding pressure or leaking pressure down while not running.

My question is which Airtex pump is the right one? I searched the forums and have seen several posts calling for these: E8335, E3270, E320, E-3270 & E-3240. I am going to try to go this route, as I would rather spend 80 dollars than 500 dollars. I do how ever need to know which Airtex pump is the right one.

 

Do you have secondary Air or not?

 

I went through this a few weeks ago...everyone said the e3270 (i think thats the one) was the replacement, but it isn't...not even close, the airtex E8335 is a direct replacement for the d2, mine bolted right up and it worked with the pump cannister designed with secondary air and with, i know this because my original pump did not have SA, but when i replaced the pump i realized my cannister had a crack so i got a replacement from a junkyard that had SA and the pump went right in. Just be careful when you remove the original pump out of the cannister, you'll need to kncock it out from the bottom of the cannister where gas is sucked up through, do NOT try to pry it out, the cannister will crack, i know this first hand and it cost me. If you need any help please let me know, like i said, i just went through this a few weeks ago

 

I do not have Secondary Air Injection. So which is the right one for my application?

 

The e8335 will work for both...its hooks right up

 

Thanks! Local parts store has it for $70.00. Here we go!

 

My mechanic called me and said that after he got the fuel pump assembly out and looked at it he doesn't think replacing the Airtex pump will fix my problem. He says there is something on the top of the assembley that controls the "bleed back." A one way valve of sorts? He now suggests that I buy a new pump assembly based on the problems I'm having and not install the Airtex pump. What do you guys think?

He also mentioned that the hoses on the inside of the assembly are shrink wraped to the parts and he doesn't have the equipment to reproduce this. What do you guys do about this problem? Hose clamps?

 

there are only two things that need to be switched over, the main power plug, and a rubber line that goes from the black cylinder which surrounds the actual pump, the rubber line is on there pretty tight but just snip it off of the old pump as close as possible and just stick it on the new pump, to be safe, use a steel hose clamp, make sure it's stainless. i don't know what he could be talking about at far as "bleed back" because the pump is what keeps it from bleeding back, sounds to me like replacing it should do the trick

 

It's running. The Airtex E-8335 is a direct replacement. It has 70 to 100 psi to boot. Fuel pressure shouldnt be a problem haha. My mechanic did say that he had to remove a part of the assembly that was keeping it from pumping. A "cannister" is what he called it. It runs great and he stands behind the repair so I'm happy. Especially since I didnt have to pay $550.00 for a new pump assembly plus labor. Total shop bill including labor, clamps, hose $185.00. The Airex is the way to go on this repair. My screen/filter was spotless and was able to be re-used. If you have the time to do it it's even cheaper. Just pull te cargo area carpet up and remove the access panel to get to it.
