Mechanical fuel pump
Posted by: 4carbcorvair ()

Went to start the Monza, no go. No fuel. I installed and old original to get it going only to have this one leak like a sieve. I know Clarks had a bad run of pumps, I was honored by purchasing a couple. Are Clarks newer pumps better? Any other recommendations?? If quality isn't good, I'll go electric, been running the Airtex in my Corsa for 13 years now. smiling smiley

It doesn't leak, it's marking it's territory.

They say the pumps now are better, but you may be just as well to get a pump through O'Riely or NAPA. The main problem the last year or so seems to be the soft zink alloy base on the new pumps warps from screw tension, causing internal leakage which causes it to become weak or stop pumping. A good fix it to replace a warped base with an original A/C pump aluminum base - if you can find one.

I have 9 of the bases and springs I won't be using. Anyone wanting to buy one can PM me. I will be taking the original bases and springs to Helen with my sale package.

Last year at O'Reillys I found they had gone from $44 to $92. I had been buying them and taking them apart to reduce the pressure but won't do it for that kind of money.
Clarks pump seems to have less pressure in the $65 neighborhood but if they have a tendency to warp I'd rather not.

I've been installing Airtex E8016S with a toggle switch and inertia switch for safety.

I like to think I fought the good fight with the mechanical pumps but I'm tired.

Did you tighten the screws? There used to be a paper in with the old pump that stated the screws were not tightened all the way and needed to be tightened before use.

I am using the eBay Globe electric pump $12 clones. I have a relay to control it the inertia switch, the Chevy Vega low oil pressure switch and an indicator light when power is supplied to the pump. One wire from fuse box IGN fuse to the engine compartment with a 1 amp fuse protecting the relay circuit. And one wire from pump to relay in engine compartment.

It will shut down in an accident or if engine has low oil pressure.

I also carry a jumper wire to jumper power wire to pump power wire, if any problem occurs with the circuit.

I will figure out a way to add a pressure switch on the engine line, so I can see when pressure is lost. I will tie it into the pump power wire so it will not illuminate unless pump is powered and pressure is in the line.

Rock Auto has Airtex for 44 and Carter for 74.

My last pump was from them, [the Airtex] and it has been on for 2 years now with no issues, but I did change to an original spring.

I've been buying Airtex on Ebay from JC Whitney for about $44.
I won't take a chance on a cheaper clone. The extra $25 doesn't seem like much in the midst of a failure.

Thanks everyone! Ordered an Airtex after doing some reading and price checking. The car had a newer AC Delco pump in it. I installed the original GM pump and that sprayed gas all over the engine even after tightening the screws. Knowing the Airtex in my Corsa is 13ish years old and still pumping, I decided to go to electric in the Monza. $39.99 at Summit Racing.
