Great high quality part at a great price ! Honda Main and Fuel Pump Relay
At Several Honda owner websites , people boldly stated that this relay was no longer available anywhere ! I just bought this one at half the price that O'Ri wanted. From pictures, appears to be the exact same part. I crawled up under the dash, got to left of clutch pedal arm. Swapped ( easier to say than to do ) out old for new. 1993 Honda Del Sol fired right up. Excellent Part at a bargain price with SPEEDY FREE SHIPPING. Trouble had been intermittent, was finally able to isolate trouble to be lack of fuel. Easily ordered relay on line. Website is easy to navigate, has clear pictures and discriptions. Adding to my cart and Checking out, was a breeze. Right Part at Better than the Right Price. FREE Shipping. How can they do it ???? AMAZING Thank you to Everyone at 1A AUTO for a smooth transaction and for the great Website.
