Full StarEmpty StarEmpty StarEmpty StarEmpty Starnot funny
by Gerald from Napa, California on March 07, 2013
I have already corresponded with you twice about how unhappy I was with the last shippment.I guess you didn't believe me or the word wasn't passed down. Now that doesn't suprise me.I did exchange a couple of futile emails with some air head that could care less about customer service.Next thing you would probably tell me is he was service all star of the year. I paid $13.00 for a three day delivery that took six or maybe seven due to factors you claim were out of your control. These small liteweight gaskets could have been sent in a regular envelope but nope they had to come in a stupid big box expensive and late at that.I will be buying more marine products in the future.I own a large cruiser and a smaller boat as you know call for continued upkeep. In the future I will not be spending another penny with your establishment. That by the way is how it works. Crappy service and some bone head that could care less giving lame excuses as to why this didn't go of as needed.Please remove any acount information you have. I will think about you when I spend however much on marine parts from someone a little more accomadating.If you find this email humorus there in may be part of the problem.

Q:
Will this fit in place of ford 5.0 ltr 913682?
A:
We will need the cubic inch information and year in order to match up parts. If you can provide the serial number that would be the best option if you can get it.
Q:
I just took down my 1975 198. I found that the port side elbow riser did not have a blocking plate and the starboard side does. Should both sides have the blocking plate?
A:
Yes both sides should have a blocking plate
Q:
I have a 1989 merc. with 5.7 chev. 350. Looking for the manifold. What is the right one for it?
A:
We would need to cross reference OEM number so we would need an engine serial number. Contact us at the number at the top of the page with that info.
